[Nagios-users] Sending an "all is well" status report
I finally have Nagios working the way I want it and I'm about to replace our old What's Up Gold monitoring software. What's Up does have one feature that I like that I can't figure out how to reproduce with Nagios. It has a "recurring notification" feature that can send e-mail alerts containing the last few lines of the event log and "200 hosts up, 0 down". I like seeing that in my e-mail ever hour or two because it let me know that What's Up is still working correctly. I'd like a periodic status e-mail from Nagios if it's possible. I'm not sure if I'm not searching using the correct terminology or if nobody really does this. I know I could do something like write a little shell script and check nagios.log periodically for auto-save entries, I'm just wondering if there is some builtin way.- This SF.net email is sponsored by: Microsoft Defy all challenges.

Although I haven't been able to reproduce it on a test setup recently,
some time ago when we had a few passive checks running with Cron on all
servers we had problems with checks going stale. All the crons running
at the same time flodded Nagios with data and caused this behavior. I
didn't find the root cause at that time, but I found out that
artificially filling up the pipe while the checks were coming back in
clearly showed up the problem, although all NSCA were successfully
writing to the pipe as Nagios was reading it. I also had much less
passive checks than the default 1024 buckets in the Nagios buffer, to
this couldn't have been the issue. I reported it on Nagios-devel at that
time but haven't got any follow-ups.
I'm not sure if it only affects specific archs or have been fixed since
then, but that could be the problem you're having. OTOH the tests I ran
with OCP_Daemon were pretty hardcore, feeding it with hundreads of megs
of random check results as fast as possible, in different mode of
operation, and checking if all check results came back from the NSCA
daemon, so I'd be surprised it would have anything to do with that.
What you could try is:
1. Shutting off OC[HS]P on all but one server
2. Running -r0 to try to avoid batched results to send_nsca.
And check if it has any impact. Also make sure you have
command_check_interval=-1 in nagios.cfg on the central server.
BTW which version of Nagios and NSCA are you using?

The timeout you specify is the maximum time the plugin will take before returning, but it may take more if the number of packet * critical threshold is higher. Try on an unresponsive IP that doesn't return back ICMP errors (will depend on your network; you can try IPs like 10.10.10.10, 1.2.3.4, or an unused IP on your *local* network not going trough the default gateway). That's not a big deal since you're using Nagios 3, but if it ever find you're having too many concurrent processes or too running host on system time, reducing the timeout will certainly help.

Re: [Nagios-users] Problem with Send_NSCA on Windows
There is also writing a BAT file to do it If you already have the file
created,
This is How I Test NSCA is running when my test server is up from the
command line.
something like:
send_nsca.exe From C# Start a Process that is the Bat file,
once again, readup in the msdn library about processes and redirecting the
standard INput from consol to a filestream. both consol and filestream
inherit from iostream and thus are accepted as io for processes
I thought I mentioned this in the last message?

Re: [Nagios-users] Problem with high latencies after going distributed
Hi Mark,
I have been having similar problems with my distributed setup. The
OCSP daemon reduced the latency in returning check results greatly,
but I still am seeing (seemingly) random services go stale. I'm still
try to track down the problem, recreating it on a small scale has so
far been unsuccessful. I will let you (and the list) know how my
investigations go.
As for determining the execution time of a particular check, this can
be found in retention.dat. The field is check_execution_time=

I can see that using the OCP Daemon script cut down on my latencies
quite a lot. Unfortunately,
I'm still seeing some "stale" checks on the master server that I can't
explain. I'm starting to
get the feeling that going distributed isn't all it's cracked up to be.
I haven't seen mention in
the docs of the caveats with oc[sh]p and latencies (my books sure don't
mention it) and even the
fact that the supplied submit_service_check script in the distribution
from Ethan is a shell
script that pipes to send_nsca. I'm not all that excited about having
to do a workaround
for this issue.
While the OCP_Daemon seems to help me, I'm a little uncomfortable
running it as a solution to our
issue. First, we don't normally have root access on our boxes so
recreating the FIFOs could be
a problem (or at least a wait). I'm also concerned about requiring
another process external to
Nagios as part of the process. If OCP_Daemon dies at some point, my
distributed nodes are hosed.
I had a few issues with correctly starting Nagios and OCP_Daemon in the
right order when playing
with it last night. Once I got it all going, it worked well but I'm
thinking of having to explain
this to someone here who isn't the Nagios person.
I was thinking of your fork/exec comment above. What

You mean $HOSTNAME$. This also means that host_name in your host{}
definition much be fully qualified or otherwise resolvable.

[Nagios-users] check host_name or IP
99% of the time I can check and IP but sometimes I need to check the host_name.

Do you use regular host checks with Nagios 2.x ? Tis is not the best

Thats OK. PNP dont need this file if your using the PNP Default Mode.

First choose the right mode for your installation.
http://www.pnp4nagios.org/pnp/modes
Configure PNP based on http://www.pnp4nagios.org/pnp/config
and check the function as described on
http://www.pnp4nagios.org/pnp/verify

That's the server returning the 200 OK that nagios is properly accepting as successful. You'll want to verify that the request is actually for the host/port/url you think it is. However, based on what you've shown above and your previous post, I suspect that you have multiple copies of nagios running, one with an old configuration and one with the new.

[Nagios-users] Perf Data Issue
Hi All,
Firstly, thanks for everyone involved with Nagios, its a fantastic
piece of softwarel!
My problem is that I cannot enable performance data from my monitors.
I'm running the latest version of nagios2 which I downloaded a week
ago, and compiled it with the default perfdata setting.
I have also installed pnp successfully, however it tells me that there
are no valid rrdfiles in the given host's directory.
I've set up the follow configuration options in my nagios.cfg:
process_performance_data=1
host_perfdata_command=process-host-perfdata
service_perfdata_command=process-service-perfdata
And in my commands.cfg
define command {
command_nameprocess-host-perfdata
# command_line/usr/bin/perl
/usr/local/nagios/libexec/process_perfdata.pl -d HOSTPERFDATA
command_line/bin/echo -e
"$LASTCHECK$\t$HOSTNAME$\t$HOSTSTATE$\t$HOSTATTEMPT$\t$STATETYPE$\t$EXECUTIONTIME$\t$OUTPUT$\t$PERFDATA$"
>> /usr/local/nagios/var/host-perfdata
Notice I've commented out the process_perfata.pl line in favour of a
simple echo to a file, just for testing.
I have also restarted the nagios process to take into account my changes.
I have a host set up to monitor with the check_icmp command:
-rwsr-xr-x 1 root root 30524 2007-10-22 15:17 check_icmp
A simple check determines that it's returning performance data:
./check_icmp -H 128.1.2.181
OK - 128.1.2.181: rta 0.451ms, lost
0%|rta=0.451ms;200.000;500.000;0; pl=0%;40;80;;
And the service command looks like:
define service{
use generic-service
host_nameVirgin.Invader; All our
boxes are named after trains
service_description ICMP Echo Stats
check_commandcheck_icmp
}
Within Nagios I get the status printed without problems, but no
/usr/local/nagios/var/host-perfdata exists.
I've checked books and online articles for a solution but I guess I
must be doing something fundimentally wrong.
Any help would be massively appreciated!?
Thanks,
Paul

Re: [Nagios-users] check_http returning success full results on a urlwhich is down
Hi Mark, All,
First thanks for the quick response I appreciate your help.
The test harness is run by a simple batch script on each client machine, if I
execute it the harness is on & I can verify that with the following command
from command line, using the -s that you suggested.
./check_http -I 10.77.40.123 -p 2000 -s "QA-testHarness"
HTTP OK HTTP/1.1 200 OK - 0.340 second response time |time=0.339870s;;;0.00
size=5505B;;;0
If i close the harness I correctly get the following response with the same
command
Connection refused
HTTP CRITICAL - Unable to open TCP socket
I've edited my commands.cfg to include the -s
command_line$USER1$/check_http -H $HOSTADDRESS$ -p $ARG1$ -u $ARG2$ -s
$ARG3$
Within my windows.cfg I have altered check command for check_http to include
the -s.
check_commandcheck_http!2000!/test/results!QA-testHarness
Please correct me if I am wrong with either of these two, I'm still getting to
grips with the proper syntax to use here.
So I do a pre-flight check & reboot nagios, then via the web interface I force
a service check on check_http with the harness down so I should get an error,
however it still passes successfully.
My apache logs show no errors, and the following for the checks.

This should be failing loudly. It can't be what nagios is actually
using. The command being executed by nagios would be --
/path/to/plugins/check_http -H -p pongo -u 2000
$ ./check_http -H 172.27.0.101 -p pongo -u 2000
check_http: Invalid port number - pongo

It's getting a 200 (successful) response code from your webserver.
You're not testing what you think you're testing.
Check your web server logs to see what nagios really is checking. You
might also be interested in the -s option to verify output from your
webserver.

Re: [Nagios-users] Determining the success or failure of externalcommands
I have been digging though commands.c to see what I can find out. One thing that stands out is that Nagios 2.x calls process_external_command() which has a void return, and Nagios 3.x calls process_external_command1() which returns an int. It seems the 3.x implementation is, in fact, checking for errors in the command its attempting to process and will return -2 if it encounters any problems. This would be quite helpful in determining the status of a submitted command, but unfortunately the return value of both check_external_command1() and check_external_command2() is never considered by the calling function. Because of this, commands that are malformed or have other issues are silently ignored and check_for_external_commands() will always return OK. It seems like some effort was put into better error handling in the external command algorithm, but the changes don't seem to actually have any effect. I'm curious as to why this is, as it affects the code I am adding to track the progress of an external command from submission to completion.

I should add that this applies to the global flap detection option as well. Would you (or anyone) mind testing this on your own installation: - find a host/service for which flapping is enabled - disable flap detection for that host/service; wait until that state is reflected in the extended info - reload the configs - check the state of flap detection - has it reverted to enabled? > Not all directives can be overridden by the retention file but > flap_detection_enabled is one of them > (http://nagios.sourceforge.net/docs/2_0/xodtemplate.html#service).

I think you can get close to what you want. Servicegroups are just for
CGI display purposes but in a service definition you can specify
hostgroups instead of specific hosts.
http://nagios.sourceforge.net/docs/2_0/templatetricks.html
All Hosts In Multiple Hostgroups: If you want to create identical
services that are assigned to all hosts in one or more hostgroups, you
can do so by creating a single service definition. How? The
hostgroup_name directive allows you to specify the name of one or more
hostgroups that the service should be created for:
define service{
hostgroup_name HOSTGROUP1,HOSTGROUP2,...,HOSTGROUPN
service_description SOMESERVICE
other service directives ...
}
The definition above would create a service called SOMESERVICE on all
hosts that are members of hostgroups HOSTGROUP1 through HOSTGROUPN.
All the instances of the SOMESERVICE service would be identical (i.e.
have the same check command, max check attempts, notification period,
etc.).

This error means that either --
- $USER1$ isn't set or is set to the wrong path
- check_nfsmount isn't under $USER1$ path
- check_nfsmount is a script that calls some other program that
doesn't exist where specified.

There are other factors that you need to consider. Under 2.x, all host checks are performed serially. While a host check is being performed, up to max_check_attempts, all other nagios tasks stop completely. This can lead to unexpectedly high latencies on problem networks if you don't optimize your host check commands to complete as quickly as possible and still be confident the host is down. A single ping with 3 max check attempts for example. Just enough to be sure the host is really down. > Also, there is something else not very clear in Nagios 3 > documentation: > > (from http://nagios.sourceforge.net/docs/3_0/hostchecks.html) > "Hosts which have their max_check_attempts value set to 1 can cause > serious performance problems.

[Nagios-users] RE host checks configuration question
OK, I have find the explanation as what means a "check_interval" being set to 0 in the documentation of Nagios 3 (we are using 2.9 here): 0 means *regular* host checks are not performed. Which is good. I have another question now: Are on-demand host checks scheduled when a service transits in a *soft* not-OK state or when it transits in a *hard* not-ok state? This is a quite important question since knowing the answer to this question will influence the value I'm gonna set for the host "max_check_attempts" parameter: When "on-demand host checks" are scheduled when a service transits in a *hard* not-OK state, I will set the host "max_check_attempts" to a lower value than when "on-demand host checks" are scheduled when a service transits in a *hard* not-OK state (since I'm more confident in the service check result). Also, there is something else not very clear in Nagios 3 documentation: (from http://nagios.sourceforge.net/docs/3_0/hostchecks.html) "Hosts which have their max_check_attempts value set to 1 can cause serious performance problems. The reason? If Nagios needs to determine their true state using the network reachability logic (to see if they're DOWN or UNREACHABLE), it will have to launch serial checks of all of the host's immediate parents. Just to reiterate, those checks are run serially , rather than in parallel, so it can cause a big performance hit. For this reason, I would recommend that you always use a value greater than 1 for the max_check_attempts directives in your host definitions." Well, I believe the writer of this documentation but I don't understand why setting this parameter to 1 will serialize the host's parents checks. Can someone explain me this point?

[Nagios-users] cross products: host/host group x service/service group ..?
By-and-large, I generate my nagios configs mechanically from the same config that drives app deployment. However, I've just had cause to write some config by hand and the following occurred to me: I've got several hostgroups, and several service groups. What I'd really find convenient is a way to say all these services are running on all these hosts and generate service instances for the product of those two sets. (The hosts are part of a farm.) It's obviously possible to get a lot of the way using service templates, but as far as I can tell I still have to write a service definition per (host, service template) pair. I'm aware that there may be design issues I've missed - naming considerations or suchlike. I think it'd be desirable to be able to specify groups of hosts and groups of service templates and (with a small number of additional declarations) create service instances. So (a) am I just being dumb and missing an already-extant capability; (b) is there a fundamental reason why this doesn't fit in nagios' design; (c) is the typical thing in this situation to do what I already do and generate the configs mechanically?

[Nagios-users] notification problem Nagios 3
Hi people,
Following Question:
We have configured Nagios and so far it works fine and does notifications.
Since we have a lot of systems which belong to different groups (network, unix,
windows, ...) we tried to configure the notifications so that we can define
more then one recipient!
for example, we have contacts configured in contacts.cfg
example:
define contact{
contact_namenoone
alias noone
use generic-contact
service_notification_period none
host_notification_periodnone
contactgroups NO-admins
email [EMAIL PROTECTED]}
then we have contact groups:
example:
define contact{
contact_namenoone
alias noone
use generic-contact
service_notification_period none
host_notification_periodnone
contactgroups NO-admins
email [EMAIL PROTECTED]
}
we use the following template.cfg entries
define service{
nameprod-service
use generic-service
max_check_attempts 4
normal_check_interval 5
retry_check_interval1
contact_groups BEREITSCHAFT-admins
register0
}
define service{
nametest-service
use generic-service
max_check_attempts 4
normal_check_interval 5
retry_check_interval1
contact_groups NO-admins
register0
}
define service{
nameunix-service
contact_groups +UNIX-admins
register0
}
define service{
namenetzwerk-service
contact_groups +NETZWERK-admins
register0
}
define service{
namedb-service
contact_groups +DATENBANK-admins
register0
}
and in the services.cfg it looks like:
example:
define service{
use prod-service,netzwerk-service
hostgroup_name Netzwerkkomponenten
service_description PING
check_command check_ping!100.0,20%!500.0,60%
}
The notification only goes to the first contact /tghe one defined for
prod-service) but not to the others if wanted
The reason for this setup is that the prod-service goes to a blackberry and the
others should only be additional email notification to theresponsible groups..
anyone got an idea of what we did wrong? cant find a reason.
thanks in advance
cheers
Sigmund

[Nagios-users] CFG files - Organization
Hello guys! I've installed and configured Nagios 3 and now I am making some tests. Now, I'm wondering about the best way to organize the cfg files. I have the following environment: - Several customers - Local network - Web monitoring I`m not sure, but I think I can separate it in different directories like templates (generic templates), localnetwork (LAN), Customers (with sub folders for each customer) and so on. Also, How can I separate the cfg files? For example: - Services file - Hosts file - Hostsgroups file - Etc. I would appreciate ideas regarding the best way of how to organize it!

Well... I was thinking about partly re-writing nsca as an event-based
daemon (supporting only the --single mode, but that would be really
scalable) using libevent, allowing to pass along the timestamp (this is
a recent feature request) and supporting multi-line responses (for
Nagios 3) in the process, and finally suggesting this as a base for a
NSCA v3... I'm not even sure if I would have enough time but since my
main objective it to learn I wouldn't loose anything trying :).
In the unlikely event that I write it, In the same step I could surely
to a C version of OCP_Daemon supporting natively the "NSCA v3" protocol
(it wouldn't be hard)...
I'll have to think about it... I quess the only sane separator to write
multiple multi-line results on a pipe would be \000 (NULL), so there
would be 3 mode of operation for send_nsca (and two for nsca_sendd
(don't you think it sounds better reversed?)):
send_nsca: compatible (v2 behavior), Single check (additional lines are
taken as additional output) and multi-check (NULL separated)
nsca_sendd: single-line (one check/line, OCP_Daemon style) and
multi-line "NULL-separated).
