[Nagios-users] Help with large scale planning

[Mark Potter]

Hello List,

Been a while since I have been able to post on a regular basis due to
being given the opportunity to seek other employment! I have landed,
gracefully, in a position where I have been tasked with designing a
large scale Nagios installation. The requirements are all client
requirements and pretty necessary. I need a little advice on where to
start. I will describe the environment and then lay out my idea on how I
see the design coming together.

The environment is an HPCC environment and the requirements are based on
that aspect almost exclusively. Initially the monitoring will be for
clustering only and then expanding out to other servers outside of the
HPCC environment.

1. No client installed on compute nodes (there is an HA head node where
a client or a full install could be done).
2. No active checks directly to compute nodes
3. Ganglia is available for node data

That is the majority of the requirements. Ganglia makes things a bit
easier but I am not sure how much easier. It looks like GroundWork could
handle this but I don't see the large scale features available in the
open source version.

The environment is as follows

1. 80 clusters
2. Each cluster has 70-72 compute nodes 


The client wants a single point of monitoring for this environment. I am
looking at the following for a setup:

Using the ganglia plugin from Nagios Exchange to gather and parse the
data, on the HA head node, and having this report back to a main Nagios
server (HA) for the single point of monitoring.

What I don't know is how Nagios 3.x will scale with ~5000-6000 hosts
coming into a single point of monitoring. What cannot happen is the
checks causing any degradation in the HPCC environment. Ganglia is
already in place and accounted for in performance so querying the
ganglia process is allowed but they would prefer to pull this data from
gmetad and not gmond.

Also, from the Nagios management side, I would like to see if there is a
way to automatically add hosts if a new host pops up in the ganglia
data. This is not a deal breaker but will make life so much easier in
the long run. I have likely not given enough information somewhere but I
think there is enough here to get a discussion started.

It's good to be back!

As much as reporting them sounds nice I find only about one in ten reports 
ever has any response and only about one on five of those has anything 
done about it. I use a combination of scripts to simply null route the 
bastards and be done with them.

It truly is vague question day on the list. If the messages are making it 
to the maillog then it is most likely, in fact I am certain, not a Nagios 
issue. I suspect it is somewhere in your mailer configuration. Without 
more information there is precious little I can say. Check the Nagios logs 
to see if they are sent from Nagios, check the maillog to see what is 
happening there. If Nagios is sending them and they are making it to your 
mailer then Nagios is working and your mailer needs troubleshooting.

1. What version of Nagios are you using
2. On what OS it running
3. Attach at least the configs related to your multiple alerts. I would 
include contacts.cfg, contactgroups.cfg, at least one service for which 
you are getting multiple alerts, and so on.

I am sure someone can help you out but we will never solve the problem 
taking shots in the dark.-

[Nagios-users] Checking contents of a file on MS Windows

[mark . potter]

So I have run across one for which I can't figure out a starting point. We 
are using Tivoli to backup our farm including databases. For the most part 
this is easy to monitor as we can just monitor Tivoli. However the 
database backups are not scheduled through Tivoli but rather in their 
respective DBs as scheduled procedures. (I am not a DBA so forgive me if 
my language on that piece is off). The only actual method for determining 
the success or failure of these backups is a log file on the Windows 
server. We are using SNMP for all our Windows monitoring at the moment but 
are open to other solutions. I need to be able to access this file, grep 
out the date and status, and process those results for Nagios. Does anyone 
know of a simple way to do this and if not then does anyone know of a 
complicated method? I am not locked into to any solution and would be 
willing to use active or passive checks, snmp, nc_net, or any other 
solution. Thanks in advance for any replies or advice.

You would use hostgroup_name in the service definition and this line:

check_snmp_windows_disk!$HOSTADDRESS$!95!98!^[CDE]:

You can use $HOSTNAME$ but I wouldn't as DNS issues will then cause your 
checks to fail.-

(No Output) could be a variety of things. First run the command from the 
command line with the -v switch to see the verbose output, as the nagios 
user of course, and from there begin troubleshooting. I doubt it is option 
#2 since I have not had to modify the script on any server. If you have to 
apply a patch I would start with contacting the developer of the script.-

Just use hostgroup_name instead of host_name. That's in the Nagios docs.-

I would change all of that:

use_authentication=1

and then put the same name you used for the http authorization where you 
have the "*" on each line. Restart both apache and nagios in case there is 
any issue with the http auth and go from there. I believe, but could be 
wrong, since you have use_authentication set to 0 that it is not parsing 
anything having to do with authorization afterwards.-

Here is one for CentOS: http://www.unixservers.us/content/view/51/69/

Of course I imagine that http:www.google.com has more. As for sending one 
it's sort of hard because you haven't said whether you are running on 
Linux (what distro), BDS, Solaris, etc. I could send you mine but we are a 
SLES shop and I don't know what you run. I hope the CentOS one helps you 
out.

This is patently untrue. NRPE opens a new port and introduces new 
processes to an environment. This has to be vetted through all security 
testing and that can take months at some companies only to have it fail 
because they do not understand it. If they are admining Linux boxes 
already I am betting they have ssh running in the environment and properly 
locked down at many levels. SSH may be more powerful than NRPE as far as 
what could happen but it is also running in a lot more places. It is an 
alternative if you can't get NRPE approved. The final statement is false 
as well. "If you can't use nrpe, then you certainly can't give out ssh 
access". I can assure you that there are many environments where the 
security admins are more concerned about introducing new processes that 
use open ports than they are about giving out ssh access when properly 
locked down. It is really very simple to allow ssh access by IP and chroot 
the nagios user making ssh no more of a risk than nrpe and not introducing 
a new "threat" into the farm. The security admins are likely wrong but 
they are also the ones calling the shots in many cases.

You don't need a remote execute mechanism:
HOST-RESOURCES-MIB::hrSystemDate.0
That will pull the system date via snmp without a remote execute 
mechanism. Meaning you could, in theory, pull the date off of two systems 
with one being the ntp server, write some logic in for the lag between the 
two checks, and compare the time without any remote execute mechanism 
whatsoever. It would not be as reliable as anything using a remote execute 
method because the lag between the two checks will vary but it could be 
used as a basic check without too much trouble.

I was referring to writing a wrapped for snmp checks. Amazing that you 
suggest using snmp. I highly doubt nsca can be used if nrpe cannot. SNMP 
or SSH are likely the only options for the scenario as presented. Also I 
don't know if you noticed the OP's email address but I am betting he deals 
with a lot more red tape than most us in getting anything changed, 
installed, and so on.

Another option would to be used check_by_ssh. I am, of course, assuming 
they are allowed to use ssh but a machine with no remote connectivity is a 
problem to begin with. check_by_ssh isn't quite as nice as nrpe but it 
would accomplish the checks in question. One could also write a pretty 
simple wrapper to check the time on both servers, compare it, and account 
for the lag between the checks. It wouldn't be pretty but it would work 
for the most part.-

Depending on your version here is where you start:

http://nagios.sourceforge.net/docs/3_0/ - 3.x docs
http://nagios.sourceforge.net/docs/2_0/ - 2.x docs

If you are going to get help on the list you will likely need to give at 
least the following information:

1. Nagios version
2. OS and version
3. What troubleshooting you have done thus far

If you want support without doing any of your own troubleshooting then 
nagios.com might be your best bet.-

Yeah I tend to forget that not everyone has SNMP turned on. We have HP 
boxes and use HPSIM so SNMP is already enabled on every one of our hosts 
as part of the setup process including secure community strings and so on. 
This is a boon for me because I get to use SNMP for a majority of 
monitoring tasks and don't have to go through change control to get stuff 
installed on the farm. If you don't already have it enabled I can see it 
being a massive chore. Good point Hari and thanks for the response.

Technically Nagios can't do that. At least not from the vantage point you 
have described. We are much more granular in our monitoring for exactly 
the scenario you have described. At this point we don't combine multiple 
pieces into a single service check unless a department manager 
specifically requests a full overview in a single check. We monitor each 
piece with its own service check so we have complete control over who get 
notified for what, when they get notified, how often they get notified, 
and so on. I would say that Nagios can do what you want but that it is up 
to you to make your checks more granular.

Some systems may have issues with the "\" in a command name. I have seen 
it blow things up so there is a point on which care needs to be taken. I 
would also recommend against hard coding -w and -c values where at all 
possible. It makes using the same command for multiple services with 
different needs much more difficult. Also you should always test as the 
nagios user and not as root. Testing as root really does nothing other 
than show permissions and rights issues if the command fails to work as 
the nagios user. The script should be in libexec, owned by the nagios user 
and group, and tested as the nagios user. If that doesn't work then test 
it as root for the same dir with the same ownership to see if it works at 
all.

Re: [Nagios-users] SNMP/Windows disk usage

[mark . potter]

Melanie.

1. When you test the script are you testing it as the nagios user?
2. Does the script reside in the libexec folder under the nagios user's 
home directory?

If the answer to the above questions is yes then:

define  command {
command_namecheck_snmp_windows_disk
command_line$USER1$/check_snmp_storage -H $HOSTADDRESS$ -C 
$ARG1$ -q FixedDisk -w $ARG2$ -c $ARG3$ -m $ARG4$ $ARG5$
}
That is my command definition. $ARG5$ is an optional switch for exclusion.

One of the check commands (with security info snipped)

define  service {
host_name  
service_description SNMP - Windows - Disk - Production
is_volatile   0
check_command check_snmp_windows_disk!!95!98!^C:!-e
max_check_attempts  3
normal_check_interval120
retry_check_interval30
active_checks_enabled1
passive_checks_enabled 1
check_period24x7
parallelize_check   1
obsess_over_service 1
check_freshness 0
event_handler_enabled   1
flap_detection_enabled  1
process_perf_data   1
retain_status_information   1
retain_nonstatus_information1
contact_groups  sysalertstest
notification_interval   120
notification_period 24x7
notification_optionsw,u,c,r
notifications_enabled   1
register1
}

That is the check for our production windows servers excluding the C drive 
(the -e is the exclude switch).

I hope this information is helpful.

Contact groups cannot be grouped but contacts can be members of multiple 
groups. Bosses, in my limited experience either want to see problems when 
they happen and when they recover or when they have not been handled. I 
have yet to see a boss who really wants to see all notifications. I have 
met a couple who thought they wanted all notifications. This has never 
lasted more than a week before escalations were implemented. See the 
documentation for escalations: 
http://nagios.sourceforge.net/docs/2_0/escalations.html

This is accomplished by using escalations.

I, personally, never recommend using the distro package for nagios. 2.6 is 
older, the packages are not maintained by Ethan, and the latest version is 
2.10. We are a SLES shop and SLES is pretty good about updating their 
packages but I much prefer to compile Nagios from source to have that 
little bit of control. I would check the online docs concerning your 
problem and download 2.10, compile it, and go from there. Your other 
problems are all handled by escalations pretty easily.

Re: [Nagios-users] SNMP/Windows disk usage

[mark . potter]

You will need to actually download the plugin from 
http://nagios.manubulon.com/snmp_storage.html as it is not part of the 
Nagios plugins package but rather a third party plugin.

Re: [Nagios-users] SNMP/Windows disk usage

[mark . potter]

Melanie,

I have setup the plugin available here: 
http://nagios.manubulon.com/snmp_storage.html and it works perfectly for 
our needs. It uses SNMP so you would have to have SNMP setup on all of 
your Windows boxes but with that caveat it is the best solution I have 
found for monitoring windows partitions. If you are looking for something 
slightly less complicated or with fewer options there are many plugins on 
nagiosexchange.com that will do the job. I would recommend 
check_snmp_storage though due to the options and the robustness of the 
plugin.

That does exactly what we need. Is it listed on Nagios Exchange? Thank you 
for your response; I have managed to escape writing a wrapper thanks to 
you!

[Nagios-users] SNMP/Windows disk usage

[mark . potter]

We are using snmp to monitor our windows servers and I have had a request 
from the windows admins. They want to alert at 80% and 90% usage on C:\ 
but 95% and 98% on all other partitions. (I didn't ask about the logic 
because it wouldn't matter). I have tried multiple snmp plugins and all of 
them seem to act the same. I can monitor all the disks on a single check, 
a single disk on a single check but I cannot monitor all the disks except 
C: on a single check. There doesn't seem to be any plugins out there that 
allow exclusion and use snmp. Before I go writing a wrapper for an 
existing plugin does anyone know if there is a plugin that will allow me 
to do this? I am looking to exclude a single drive letter but check all 
the rest of the drives via snmp on windows servers. Thanks in advance for 
any advice.

[Nagios-users] How to explain active host checks to boss

[mark . potter]

Background: Due to management requirements we are using NagiosQL as a 
configuration manager for our Nagios install. NagiosQL defaults to active 
checks enabled for hosts so this is how it's been done until now. We have 
the alerts coming as we want them. We are adding more hosts and services 
weekly. I know that active host checks are not a good thing to have going 
forward as they are unnecessary. Please advise on the best way to explain 
this to the boss who is, at this moment, convinced that if we turn off the 
option in the config file then the host will never be checked even if a 
service is down. I can't find a good place in the documentation to point 
this out and would like to get these turned off in the near future so we 
don't run into issues later on down the road. Any help in pointing me in 
the right direction would be appreciated. Here is a sample host cfg from 
our environment:

define  host {
host_name   plapwnd01
alias   plapwnd01
address 10.1.254.253
parents 10.1.254-Parent
check_command   check-host-alive
max_check_attempts  3
check_interval  15
active_checks_enabled   1
passive_checks_enabled  1

host -> gateway -> router

Which is actually not much of a change from how we are already doing it.

Sometimes you can't see the forest for the trees. It was an MIB issue. 
Using the numeric OID gets the result I need. Thank you for the advice. 
Taking it step by step solved my issue:
[EMAIL PROTECTED]:/usr/local/nagios/libexec> ./check_snmp -v -H peapgse01 
-o .1.3.6.1.4.1.11129.1.1.1.0 -C public -m GSA-MIB -P 2c
/usr/bin/snmpget -t 1 -r 5 -m GSA-MIB -v 2c -c public peapgse01:161 
1.3.6.1.4.1.11129.1.1.1.0
iso.3.6.1.4.1.11129.1.1.1.0 = INTEGER: 1

SNMP OK - 1 | iso.3.6.1.4.1.11129.1.1.1.0=1

Would be nice to use the MIB but totally unnecessary and I don't feel like 
bothering to troubleshoot it.-

[Nagios-users] check_snmp issue

[mark . potter]

Thank you all for the comments on the parenting issue I posted yesterday. 
We have come up with a much easier solution than had been proposed.

I am now having an issue with check_snmp. I have used check_snmp to 
monitor this exact service in the past on other Nagios hosts and am using 
other snmp checks as well from the current host. Here is the problem:

[EMAIL PROTECTED]:/usr/local/nagios/libexec> ./check_snmp -H peapgse01 -o 
GSA-MIB::crawlRunning.0 -C public -m GSA-MIB -P 2c -d "="
SNMP problem - No data received from host
CMD: /usr/bin/snmpget -t 1 -r 5 -m GSA-MIB -v 2c -c public peapgse01:161 
GSA-MIB::crawlRunning.0

But if I run the command it shows, exactly:

[EMAIL PROTECTED]:/usr/local/nagios/libexec> /usr/bin/snmpget -t 1 -r 5 -m 
GSA-MIB -v 2c -c public peapgse01:161  GSA-MIB::crawlRunning.0
GSA-MIB::crawlRunning.0 = INTEGER: Running(1)

Both are being run as the nagios user, the second is a cut and paste of 
the command shown by check_snmp and reported to have no output. I don't 
think I have mucked up the syntax as the command produced for snmpget 
works just fine. I am probably missing something really easy here and if 
someone could point it out I would really appreciate it.

[Nagios-users] Parenting vs Dependencies

[mark . potter]

I know that this has been discussed ad nauseam and I have read quite a bit 
of those discussions this morning and over the preceding weekend. I still 
am at a bit of a loss. I have a pretty firm understanding of parenting and 
dependencies and how they both work. I think I have a good grasp on what 
we need in our environment but I seem to be missing the point in 
explaining this to my boss. So here is an overview of what I have to 
monitor, what my boss is asking, and what I think we need and maybe 
someone can beat some sense into me.

I have a medium sized network (100-200 hosts).
Hosts are in cabinets on site (no off site monitoring yet)
Cabinets are not setup by subnet (I think this is fairly normal)
1 switch per cabinet
Multiple subnets across the farm

The boss and I agree that the switch in each cabinet needs to be part of 
our monitoring setup and be part of some sort of parenting/dependency. 
This is where we cease seeing eye to eye. For the purpose of making this 
easy lets say we are dealing with three subnets and ten cabinets only. 
Here is what the boss wants (at least as far as I can understand): Setup 
three hosts per cabinet to represent the three subnets, that actual IP 
would be the IP of the switch. Parent the hosts in the cabinet to these 
and parent these to the gateways for the subnet. This is, with the 
parameters above, thirty extra hosts, and IMO a management nightmare.

Since the switch is not part of the route my thought is that we parent in 
the normal manner as I understand it, host parents to router, and so on 
and at that point we would make the hosts have a dependency on the switch 
through which their connection passes. The current setup doesn't take into 
account the switches at all but rather is setup to where each host is 
parented to it's gateway IP and that has been working rather well but if a 
switch dies we need to be able to see that via nagios and not have 20 or 
servers and their services going off all at once.. I cannot see why adding 
tens of special hosts for the boss's parenting solution will help anything 
in the long run.

Thanks in advance to anyone who takes the time to respond to this as I 
probably haven't explained very well to begin with.

You will not be able to troubleshoot when running plugins as root. Root 
has different permissions than the nagios user. Try running it as the 
nagios user. Also, you will have to put the MIB somewhere nagios can use 
it otherwise use the numeric for SNMP.

It all depends on your ssh setup. When you have tight controls for ssh in 
place, which you should to begin with, then check_by_ssh isn't an issue. 
The situation which you describe already has one box being rooted by a 
weak password and improper permissions on the private key file. SSH is a 
service already running on most Linux boxes and if the sysadmin has it 
that borked to begin with then it really isn't going to matter which is 
more secure (nrpe or check_by_ssh) because the overall system is at risk 
from the ground up. 

Nothing is un-exploitable but we all try to make sure our systems are 
secure. In our case it made sense to go with check_by_ssh for the reasons 
listed and not to mention we had just overhauled our ssh policies and 
implemented even more access controls. It also allowed us to not have to 
drop configurations onto multiple servers and in that way made managing 
the overall system easier.

That said I have worked for a webhost where we used nrpe and I never had 
any problems. In most cases it's six in one hand and a half dozen in the 
other. It all boils down to the environment into which you walk when 
implementing Nagios. If you walk into one with a well setup ssh security 
policy and a paranoid security team the check_by_ssh is likely how you 
will end up going but in a lot of other cases nrpe is not an issue. I have 
done both and will likely end up doing both again.

Horses for courses indeed!

Currently I know of no risk associated with running NRPE however any 
service that opens a port on a system can become a risk. After much debate 
and discussion we have decided to use check_by_ssh in our environment for 
this very reason. It may not be a risk at the moment but it could become a 
risk in the future. I am not a hacker so I can't say what could happen 
with the existing code to cause a risk but the possibility remains. Our 
decision was based in simplicity as there is less to install on each 
system, fewer configurations to maintain, less risk as no new daemons are 
introduced. Everyone else may have different mileage in their own 
environments.

Sorry for the off topic post.-

The normal_check_interval is x number of units where the units are defined 
by interval_length in the nagios.cfg. If you set interval_length=10 in 
nagios.cfg and a normal_check_interval=36 then the check interval would be 
360 seconds. The answer is that you can in fact do what you have asked but 
more than likely not in the manner in which you wish to do so. You could, 
in theory, set the interval_length to 1 and then all check intervals 
throughout nagios would be in seconds. What you cannot do is use different 
measurements of time for different intervals. You have a definition of the 
units used and all intervals throughout are multiples of that unit.

For the record top posting after having been responded to in a proper 
manner makes it very hard to follow and harder to answer.

Re: [Nagios-users] host and service commands

[mark . potter]

Too much top posting to respond easily



> So are you saying the service commands run before the host commands?

The host command doesn't "run" on a schedule as such. Once state is 
established the host check will not run unless a service on the host fails 
in the 2.x series. This is my understanding and it could be wrong so feel 
free to correct me. Therefore the service command runs before the host 
command in essence but it is a bad description as the service checks run 
without regard for the host check until a service check fails. There is 
more in depth explanation that can be done but the short answer is that 
the question assumes a schedule of events that is not entirely accurate.

Max,

That works pretty well actually. I will add everyone that needs to get the 
first notification to the proper group and then escalate as you have 
shown. The logic you provided makes more sense than trying to capture to 
the first and only the first notification. Thanks so much for your help.-

[Nagios-users] Escalations Question

[mark . potter]

I have looked through the docs and the list and this seems right but I 
would like some confirmation before I implement service and host 
escalations. The situation is this: I have been tasked with getting a 
single email to helpdesk (they do email to ticket) per Nagios alert and no 
more. They don't want recovery or further notifications. This is the first 
one I have written for a group of webservers:

define  serviceescalation {
host_name plwsweb01,plwsweb02,plwsweb03,plwsweb05,plwsweb06
service_description Apache - Maximum Connections 
Check,HTTP - Port 80 Check - Production Systems,Ping - Simple Ping Check - 
Production
contact_groups  helpdesk,sysalertsinfra
first_notification  1
last_notification   1
notification_interval   30
}

According to my understanding, and I could be wrong, this will send the 
first notification to groups (helpdesk and sysalertsinfra) and the rest, 
if I define no further escalations, will go the default contact for that 
group.

The other questions I have are:

1. Are the multiple services/hosts allowed here?
2. Is there a better way to do this?

Thank you all, in advance, for your time.

Jasper,

I have sort of the same issue and you have already stated the most 
expedient, and indeed only, solution that I found. Two services with 
different time periods for checking. It's doesn't look as pretty in the 
web interface but it works like a charm. The other method would be to 
write a wrapper that performs the check and alerts on the value you set 
based on time. This wouldn't be hard to do to be honest but it seems like 
re-inventing the wheel to some degree. The other question I have is if the 
servers are capable of withstanding a load that high why not just have 
your high threshold set the same all time? My situation isn't load based 
but with the standard Nagios plugin you can alert on any of the three 
points that uptime returns (here I make the assumption you are monitoring 
*nix boxen). If the situation calls for being able to be alerted to spikes 
during normal operating hours then you will either need two checks and 
time period for each or a wrapper that checks the time and returns an 
alert based on the time and load.

Mark L. Potter

Double backslashes produce the same results unfortunately. It doesn't make

[Nagios-users] Line breaks in notifications ignored

[mark . potter]

I am pretty sure I have seen the answer to this but I have searched the 
archives, google, and my own archives (since I joined the list) and can't 
seem to find where I saw this mentioned before. I have notification 
commands such as:

define command{
command_namehost-notify-by-email
command_line/usr/bin/printf "%b" "** Nagios **\n\nNotification 
Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: 
$HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | 
/usr/bin/mailx -s "Host $HOSTSTATE$ alert for $HOSTNAME$!" $CONTACTEMAIL$
}

When I run: /usr/bin/printf "%b" "** Nagios **\n\nNotification Type" from 
the command line it appears correctly, with the \n inserting a line break, 
however when Nagios sends an alert I get the alert with no line breaks and 
an"nn" or "n" (depending on the break) where it should have been. I am 
stumped at the moment. I have been over the docs but only found the macros 
listing. I have a sneaking suspicion that it may have something to do with 
2.9/2.10 upgrades but that didn't make much sense to me. I have tried 
escaping the breaks but the same thing happens as if there weren't any 
escapes there at all.

Nagios 2.10

Any help at all, even just the right google phrase for which to search, 
would really be appreciated!

[Nagios-users] Non-support/Interface question

[mark . potter]

I have been tasked with creating an easy to view frontend for our 
helpdesk. I was using NagVis for their frontend but their latest request 
seems both a little basic and sort of complex for NagVis. I am hoping 
someone will be able to recommend a method of doing this that is easy to 
maintain. What they, essentially, want is a table with three columns. The 
first column will be the name of the hostgroup, the second would be the 
applications for the hostgroup (A single indicator for all apps that goes 
red if a single app fails), and the third would be the actual hosts. The 
second two columns are simply a red/yellow/green indicator with some 
fourth option for acknowledged problems while the first will be text large 
enough to read on their wall mount plasma screens. I could do this in 
NagVis with a background image for the columns/rows but it seems it would 
be much simpler and easier to maintain as php, html, perl etc. I could 
code such a page but do not have the in depth knowledge of Nagios to hook 
in and get the status information needed for the page. Does anyone know of 
a tool that will accomplish this without much trouble or an easy guide to 
developing such a thing? Thanks to all in advance for an replies.

Please disregard the above request. Further research showed the -S option 
was all that was needed. Would be nice if this was documented to show it 
is needed on all systems with banners as it is currently a little harder 
to find. If it were mentioned in the -h, the banner part, I would not have 
sent the request for help initially.  I now return you to your regularly 
scheduled madness...-

[Nagios-users] check_by_ssh failing on commands that work via remote ssh as the nagios user

[mark . potter]

Nagios: 2.10
Plugins: 1.4.9
OS: SLES 9.3

I am having some trouble figuring out how to make check_by_ssh work 
properly. I think I have done all of the usual troubleshooting and I have 
googled the issue to no avail:

Command as nagios user on the remote server:

/usr/local/nagios/libexec/check_load -w 7,7,7 -c 10,10,10
OK - load average: 0.01, 0.04, 0.03|load1=0.010;7.000;10.000;0;

Command as nagios user via ssh on Nagios server:

ssh ulwswas01 "/usr/local/nagios/libexec/check_load -w 7,7,7 -c 10,10,10"

OK - load average: 0.05, 0.07, 0.04|load1=0.050;7.000;10.000;0;

check_by_ssh attempt as nagios user on Nagios server:
/check_by_ssh -H ulwswas01 -C "/usr/local/nagios/libexec/check_load -w 
7,7,7 -c 10,10,10"
Remote command execution failed: 

I get nothing in the log files concerning this and it makes little sense. 
I have tried everything I need to have working, to the best of my 
knowledge, as the nagios use and it works. Thanks in advance for any help!

[Nagios-users] Slow Nagios reloads with NDOUtils

[mark . potter]

I really wish I could be more descriptive in the title but I am afraid it 
would make a very long title at best and be confusing at worst. For 
starters I am using the following:

SLES 9.3
Nagios: 2.10
Nagios Plugins: 1.4.9
NDOUtils: 14b6
NagiosQL: 2.00
NagVis: 1.1

My first problem, and I am not sure it is actually a problem, is that when 
I do a reload of nagios (/etc/init.d/nagios reload) it takes, what seems 
to me to be, a long time. It is usually around 90-120 seconds for Nagios 
to start allowing use of the web interface once the reload is initiated. A 
check of the files reveals no errors (save one warning for a host with no 
services) and the nagios process shows in a ps awux list. However the web 
interface shows the "Whoops! Error: Could not read host and service status 
information!" during the 90-120 second delay I mentioned earlier. Here is 
a tail of the logfile for the shutdown and restart:

Nov 16 15:16:19 ulapnag01 nagios: ndomod: Shutdown complete.
Nov 16 15:16:19 ulapnag01 nagios: Event broker module

services associated with it!

We are monitoring:

# Active Host / Service Checks:272 / 329 

This doesn't seem like enough to bog down a Dell PowerEdge 1855 with 2GB 
RAM onboard. Any and all help would be appreciated. I have been banging my 
head against the wall on this one. I have tried searching cannot seem to 
find these symptoms anywhere. I am being pressured to put this system into 
production but would prefer to have it restart as quickly as the current 
production system (never have had any lag reloading) so that I don't have 
to schedule daily restarts to test changes as they are being requested 
fast and furious. I apologize if I have over explained. Thanks in advance 
for any help!

What exactly are you wanting to monitor? Are you looking to make sure 
certain things are installed or trying to make sure that nothing outside 
of certain things get installed? I think that more information is needed 
in order to discern what is best for you.-

check_snmp -h in the libexec dir will give you the information that you 
seek. You will need to define a command but check_snmp should do what you 
need it to do.-

I seem to remember there being notification issues in some of the 3.0bX 
versions. If this is for production it is recommended that you use the 2.X 
version (currently 2.10). The cmd file not found coult be a permissions 
issue. But as far as 3.0bX goes I wouldn't use it in production 
environment and for testing I would use the latest 3.0b5 and see if that 
changes any of the issues you might be having.-

It sounds like you have not properly setup your htaccess and htpasswd 
authentication. This can be found in the documentation here:

http://nagios.sourceforge.net/docs/2_0/installweb.html

and here:

http://nagios.sourceforge.net/docs/2_0/cgiauth.html

Nagios does not come with a user already setup. You will have to follow 
those docs to setup authenticated users.

Thank you for the response. It is, however not a 64 bit system.

# cat /etc/SuSE-release
SUSE LINUX Enterprise Server 9 (i586)
VERSION = 9
PATCHLEVEL = 3

However I have realized that I should be posting to the plugins list and 
not here. My apologies to everyone. I am off to post to the correct list.-

[Nagios-users] Nagios Plugins 2.10 build problem

I cannot see a requirement in ./configure for a newer version. I tried to 
use gnutls and met with the same sort of issue. I feel it is something 
obvious I am missing. Any help would be appreciated.

[Nagios-users] Customizing statusmap.cgi

[mark . potter]

I am interested in customizing statusmap.cgi to use hostgroups instead of 
single hosts. We are already using a patch that displays the hosts on a 
google map and management wants a map of the hostgroups at location, shown 
on the map, for the NOC to watch. I won't venture off into my lack of 
support for this idea but suffice it to say I have been tasked with 
accomplishing that. The easiest method, so it seems to me at the moment, 
is to use the googlemap patch combined with patching to use hostgroups 
instead of hosts. I am not much a c hacker so I am at a disadvantage as to 
how to get this working. Any and all help would be appreciated.

[Nagios-users] Nagios slow restarting/reloading possible NDOUtils issue?

[mark . potter]

I have gone over the documents again this morning and don't think I missed 
anything. Here is all the relevant information I can think of as well:

OS: SLES 9.3
Nagios: 2.9
Plugins: 1.4.10
NRPE: 2.9
NDOUtils: 1.4.9
Addons: NagiosQL, NagVis

This system is in the testing phase at this time so I can do anything that 
needs to be done.

When I reload nagios (/etc/init.d/nagios reload) it takes upwards of a 
full minute to bring everything back up for viewing. In the meantime a 
message is displayed concerning the status of the nagios daemon:

Error: Could not read host and service status information! 

This goes away in between 90 second and two minutes and everything begins 
to function normally and the system goes on that way until the next time I 
have to reload the configuration.

The suggestion on this page are:

1. Check the Nagios log file for messages relating to startup or status 
data errors. 

[1191938804] Caught SIGHUP, restarting...

rformance data file will not be processed!
[1191938804] Warning: Service performance file processing command 
'process-service-perfdata-file' was not found - s
ervice performance data file will not be processed!

2. Always verify configuration options using the -v command-line option 
before starting or restarting Nagios!

Done and nagios is actually running

3. Make sure you've compiled the main program and the CGIs to use the same 
status data storage options (i.e. text file or database). If the main 
program is storing status data in a text file and the CGIs are trying to 
read status data from a database, you'll have problems.

This is where I suspect the issue might be hiding. I am using NDOUtils and 
did not compile nagios is any special manner. I suspect, if this is 
actually an error, that it is somewhere in the text files vs. DB issue. I 
could be insane and this just could be how long it takes nagios to HUP 
when using NDOUtils. No matter the issue I suspect this list is where I 
will find my answer. Thanks in advance for everyone's time.

Re: [Nagios-users] FW: Problem with NDOUtils 1.4b6 and MySQL

[mark . potter]

I have found the issue. The RPMs from mysql do not contain the proper 
shared objects. Installing MySQL from source solved the issue. I now have 
NDOUtils, NagVis, and various other customizations running flawlessly. 
Thank you all for the suggestions.

Thank you Mr Wheeler and Hugo for your advice. I have snipped the output 
of the suggested command from Mr. Wheeler.

checking for mysql_store_result in -lmysqlclient... no


*** MySQL library could not be located... **

You chose to compile NDBXT with MySQL support, but I was unable to
locate the MySQL library on your system.  If the library is
installed,  use the --with-mysql-lib argument to specify the
location of the MySQL library.

NOTE: After you install the necessary libraries on your system:
  1. Make sure /etc/ld.so.conf has an entry for the directory in
 which the MySQL libraries are installed.
  2. Run 'ldconfig' to update the run-time linker options.
  3. Run 'make devclean' in the NDBXT distribution to clean out
 any old references to your previous compile.
  4. Rerun the configure script.

TIP: Try the following

 ./configure --with-mysql-lib=/usr/lib/mysql




checking mysql/mysql.h usability... yes
checking mysql/mysql.h presence... yes
checking for mysql/mysql.h... yes
configure: creating ./config.status
config.status: creating Makefile
config.status: creating src/Makefile
config.status: creating include/config.h
config.status: include/config.h is unchanged


*** ndoutils 1.4b6 09-27-2007 ***


Type 'make' to compile the NDO utilities.


That is running : ndoutils-1.4b6 # ./configure 
--with-mysql-lib=/usr/lib/mysql --with-mysql-inc=/usr/include/mysql 
--disable-pgsql 

I should have been a little more clear. I spent yesterday going over the 
archives in depth and trying solutions for issues that seemed to be the 
same or similar. Thanks to everyone for such quick responses!


I noticed I had not specified my actual distro, although it could have 
been derived from the RPM output, I am running SLES9 with full updates, 
upgraded MySQL (as shown in my first email), and while it doesn't matter 
just yet Nagios 2.9.-

[Nagios-users] Problem with NDOUtils 1.4b6 and MySQL

[mark . potter]

I have been trying this for a day now and it is time to ask for some help. 
I have included the full output of the configure, as well as RPM output 
and directory listings. Any help would be greatly appreciated. It seems 
that NDO cannot find what it is looking for in regards to mysql yet AFAIK 
everything is there. Please advise if something is missing, or if I should 
compile mysql from source, or any other fix. Here is all the relevant 
information I can think of this morning:
