Re: [Nagios-users] serious performance issue

[fancyrabbit]

i met almost the same issue.
after tweaking enable_embedded_perl=0, the load average was brought up but
latencies became lower.

[Nagios-users] serious performance issue

[shadih rahman]

I am seeing a ton of orphaned error message for both services and hosts.  I
am running nagios on a quad core 2.2 GHZ machine running 4 GHZ memory.  I
will paste my configuration file below.  I have the machine sending ndo to a
local database sitting on a 170 GB Hard drive.  nagios is obcessing on both
host and services and sending data to a machine with identical
configuration.  I am doing failover using NSCA.  Please advise on this.

How about if you add a "-v" to get verbose output?

Also, you may want to check the return code from the manual run on an OK
resultx (for example, by running "echo $?" aafter your check_snmp
command to make sure it matches what you see in the output).

What happens in my case occasionally is that I install a screwed-up MIB
for an unrelated service. It won't show any obvious errors, but it will
cause check_snmp to return a warning result code regardless of whether
the SNMP result falls within my thresholds.

In effect, it's warning me that my MIBs are hosed, based on
the fact that it got a non-OK result from snmpget (which is what
check_snmp calls to do the actual SNMP getting).

If you a numeric OID rather than "mib-2.33.1.2.4.0" and pass the "-m :"
then check_snmp (and, by extension, snmpget) don't need to load the MIBs
at all, so you don't get an error if you've got a bad MIB.

Re: [Nagios-users] Some hostgroups NOT displaying (weirdness) SOLVED

[Frater, Greg J]

Okay, I apparently have not learned the lesson to check the archives
first.  I found the answer there
(http://article.gmane.org/gmane.network.nagios.user/45395/match=hostgrou
p+not+display), I did not check there until after I posted.  Anyways for
future reference our problem was due to NOT having the web ui users as a
contact of a hosts in the offending hostgroups.

Subject: [Nagios-users] Some hostgroups NOT displaying (weirdness)



Greetings All, 

I'm pretty lost and could use some help.  We are moving a Nagios 1.x
setup to Nagios 3.0.6.  We have about 550 hosts and some 5000 services.
About 3/4 of the way through our migration of config files we noticed
that some of our hostgroups are not showing up in the web ui,  but I
have yet to figure out why.  There are certain hostgroups (but not all)
that are not displaying and if they are listed in the
'hostgroup_members' directive of another hostgroup it will cause the
second hostgroup not to display either.  I've tried every combination of
member and hostgroup_members that I can think of but so far the only way
I can duplicate the problem is use one of the known problem groups.
Does anyone know what the logic or rules are that are used to determine
if a hostgroup will display in the web ui or not?  Any other suggestions
on what to try to track this down?  Any help is appreciated.

Thanks, 

-greg

No, Nagios nor NSCA will not buffer/resend results.

I honestly don't know if it will buffer and resend, but at the very 
least, the individual processes will sit there waiting to timeout, which 
dramatically increases your check latency since Nagios has a max process 
limit.  I have a setup where the distributed instances can "self 
promote" if they lose touch with the master, and the timeout issues made 
it completely unreliable because of the increased resolution.

Look into OCP Daemon 
(http://www.nagiosexchange.org/cgi-bin/page.cgi?g=Detailed%2F2521.html;d=1) 
- it solved my problem.

Re: [Nagios-users] Nagios Warning Bug/Misconfiguration

[Thomas Donnelly]

Thanks for the quick reply!

Ran from the command line got:

# ./check_snmp -H 192.168.97.71 -o mib-2.33.1.2.4.0 -C secret -w 95: -c 75:
SNMP WARNING - 100 | SNMPv2-SMI::mib-2.33.1.2.4.0=100

# ./check_snmp -H 192.168.97.71 -o mib-2.33.1.2.4.0 -C secret -w 95 -c 75:
SNMP WARNING - *100* | SNMPv2-SMI::mib-2.33.1.2.4.0=100

So by intentionally triggering it again (remove ":"), it shows the *'s



Not really sure what they mean by:

1. Prevent check_snmp from loading the MIBs (default behaviour) by using 
numeric oids AND using the "-m :" option

[Nagios-users] Distribuated Help

[Christopher Burke]

I need an answer that I haven't been able to find in any docs or web
searches.

 

I want to set up a distributed monitoring scenario using NSCA, but I
need to know if the Client will buffer checks when the connection is
lost to the central server, and then send them when the connection is
restored.  

 

Basically I want to continue to monitor a sites hosts even if the WAN
goes down so I have information during that timeperiod.

 

Thank you

 

Christopher

this is just the system installation of the esx servers. It's a raid 1
sas array. I need to know when the disks go south because the whole
datacenter is moving to a cybercenter where we longer can rely on the
typical visual checks when changing the tapes.

please, do upload it. I have (at this point) no use for it, but I am
sure someone else will. Nagios is great because of all the plugins.

Hi Giorgio,

thanks again for your input. I have found a RAID.mib (unfortunately,
it is not in the esx rpm package, but in the windows package). I have
copied it to the net-snmp collection of mibs and am reviewing it. If
you will like to have it I will send it off list (it's a bit big to
send to everyone on the list).

I am going through it and it looks promising.

.iso.org.dod.internet.private.enterprises.sni.sniProductMibs.fscRAIDMIB.svrObjects.svrStatus.svrStatusLogicalDrives.0
= ok

.iso.org.dod.internet.private.enterprises.sni.sniProductMibs.fscRAIDMIB.svrObjects.svrStatus.svrStatusPhysicalDevices.0
= ok

Tomorroy I will try removing some disks from the server and check if
those result change as well when the disks are not there.

As soon as I get a working script to check the health of the disks I
will post it for review in nagiosexchange (I can code some Perl, but
am no Perl expert, just a sysadmin trying to control a crazy
environment).

[Nagios-users] Adaptive Monitoring: Broken?

[Patrick Morris]

Here are the important stats:

Nagios Version: Version 3.1.0
Proficiency Level: Pretty damned high

It's been a long time since I had a question to ask here, but I've run
into an issue that's had me ripping my hair out for the first time in
many, many years of working with Nagios.

For various convoluted reasons, I have some services with a notification
command that includes the following:

/usr/bin/printf "[%lu] PROCESS_SERVICE_CHECK_RESULT;$HOSTNAME;$SERVICE;0;OK - 
Not a real check\n" $DATE > $CMDFILE

/usr/bin/printf "[%lu] CHANGE_SVC_EVENT_HANDLER;$HOSTNAME;$SERVICE;check_ok\n" 
$DATE > $CMDFILE

/usr/bin/printf "[%lu] CHANGE_SVC_CHECK_COMMAND;$HOSTNAME;$SERVICE;check_ok\n" 
$DATE > $CMDFILE

check_ok is defined like so:

define command {
command_namecheck_ok
command_line$USER1$/check_dummy 0 "Not a real service"
}

While the first command works fine, and sets the service to an OK state,
the next two (which I've tried in various combinations) show up in the
Nagios logs as having been sent, but do nothing. The check that appears
in the config files keeps running instead of my check_ok check.

Here's how it shows up in the logs:

[1239128528] EXTERNAL COMMAND: CHANGE_SVC_EVENT_HANDLER;dummy-host;DNS;check_ok
[1239128528] EXTERNAL COMMAND: CHANGE_SVC_CHECK_COMMAND;dummy-host;DNS;check_ok

I've noticed the message is different if I use an invalid command, so
I'm relatively sure I'm using the right ones; they just don't do
anything.

Event handlers are enabled for these services, but even if they weren't
the check command should change, right?

Am I doing something wrong here, or have I run into a bug?

[Nagios-users] Nagios Warning Bug/Misconfiguration

[Thomas Donnelly]

Hi all,

I am having an issue with all of the devices I added showing warning all 
the time. It is a simple snmp check to see if the amps are above 
160warn/180critical. They always say warning even though they are less 
than the specified 160. One thing to note is once it hits the 160 mark 
it gets the * value * in turn, showing that it is actually in the 
warning range. I have shown the neccesary data I hope below. Any/all 
help is greatly appreciated.

What exactly is your 'disk array'?  A SAN?  I have a script for nagios  
3 which checks the sensors (temperature, voltages, etc.) via SNMPv1 on  
a fsc FibreCat SX san and a Brocade fibre switch.  I don't know,  
though, how I can check the disk health this way.


I think I will upload that script to nagiosexchange, if you think you  
could use it...


Best, Albrecht.

Hi,

as I told you, all depends on the richness of the MIB. Find the MIB for your
server and send it to me. With that in my hands I will be able to tell you if
you can do that.

I get
Timeout: No Response from ipaddress
Timeout: No Response from ipaddress
Timeout: No Response from ipaddress
Timeout: No Response from ipaddress

I tried with almost allt he firewall in our network but go ththe same
result.

./check_cisco_firewall.sh -H 10.21.1.4 -V 1 -C public -M failover
(from command line)
Timeout: No Response from 10.21.1.4

Hi Mr Gabriel. We recently switched email service at op5, and apparently
emails from some systems are getting stuck since then.

I have forwarded your email to the relevant parties at op5 and I'm sure
someone will get back to you very soon and that the problem will be
fixed asap.

Thanks for reporting this, and for your interest :)

Re: [Nagios-users] monitor primergy servers with esx

[Giorgio Zarrelli]

Hi,
Hi,

first find the right mib describing your hardware. Second step, enable snmp v3
on your fujitsu and at the end you write a script.

Actually I wrote a nagios plugin to check memory and cpu of F5 BigIP and
another for monitoring bandwidth via snmp. all resides on finding the right
oids which match the values you are going to collect through snmpget.

To collect a value, for bandwidth, let's say, I use such a string:

SPEED=`/usr/bin/snmpget -v 3 -t 1 -r 5 -m '' -v 3 -l authPriv -a MD5 -u
${LOGIN} -A ${PASSWORD} -x DES -X ${PASSWORD} ${HOST}:161
IF-MIB::ifSpeed.${IFINDEX} | cut -d " " -f 4`

[Nagios-users] monitor primergy servers with esx

[Natxo Asenjo]

hi,

I have some fujitsu-siemens primergy rx-300 s3 that I monitor with the
check_fsc.pl and snmp. This works fine.

I have installed the serverviewraid manager tool from fujitusu siemens
so that I can monitor if the disks are ok. This works.

But, here comes the question: how do I monitor the health of the array
controller if I cannot install nagios-nrpe in the boxes? installing
nrpe is not supported by vmware, so the option is pretty closed.

I monitor citrix servers with the same tool, amcli and a batch script
through nrpe.

Has anyone gotten to monitor it through snmp? Would you care to show how? ;)

[Nagios-users] op5 signup for demo issues?

[Gabriel - IP Guys]

Dear All,

I'm not sure if this counts as off topic, but I am having a very  hard
time signing up for the op5 demo downloads. I receive no email
responses. I know there are some op5 guys on this list, so feel free to
help me out on this one!

Perfect, at least the documentation is consistent. So it all boils down to a
missing warning when we forget to define a check_period where it should be
mandatory.

I guess its a matter of taste, but I'd expect the program to trigger a hard
error when trying to read its config files and then missing something
mandatory. The current behaviour is to my knowledge
undocumented/undefined/random.

Hi Morton,

  according the documentation (http://nagios.sourceforge.net/docs/3_0/
objectdefinitions.html), check_period is mandatory for both hosts and
services! And thus, nagios should report an error in both occasions!

Sorry, cu l8r, Edgar.

But not with a host...  well, I had hoped for a more consistent logic here.

And how?

My trials here shows that it tests 24x7 if I omit the check_period. Fine
thats what I want.

But as you point out yourself too, the logic is not straigth forward here.

For a given value of "well defined", yes ;-)

By checking the service as if you'd defined a timeperiod encompassing all the
hours of all days (I think). It could also be by not checking the service at
all, which one could argue is actually correct. Try and find out.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.

[Nagios-users] "strange" warnings from the config files

[Morten Guldager]

'Aloha!

How come that I get a warning if I omit the "check_period" on services while
it seems to be ok to leave it out on the hosts?

It says:
Warning: Service 'check-stuff' on host 'nice-box' has no check time period
defined!


Will nagios act well defined if I simply ignore these warnings? And how?

I've already recommended one to  you -
   [quote] An excellent way to get started with Nagios is to read the book
   "Nagios" by Wolfgang Barth.  http://nostarch.com/nagios_2e.htm [/quote]

This book can be purchased as a .pdf download, so you can buy it right
now if you wish.

You will find other documentation on the NSClient++ web site, but if
you want an easy to follow guide to monitoring windows servers with
Nagios, I firmly believe Wolfgang Barth's book is by far the best for
you.

Cheers,

Jim

Re: [Nagios-users] more than a variable in a pnp4nagios graph

You can use DRRAW http://web.taranis.org/drraw/ .  I believe it can be
done within PNP too, but I haven't tried it.  This was discussed on
the pnp4nagios email list recently.  Check the archive at
http://sourceforge.net/mailarchive/forum.php?forum_name=pnp4nagios-users
for the thread "generating gathering graph from several host /
services".

See also the recent threads in the nagios-users email list with the
subject "pnp4nagios - view graph for disabled service".

hth,

Jim
