[Nagios-users] accommodate 7426 passive checks on nagios 3.0.3
Hi all, I have 7426 incoming passive checks on my nagios server. I turned on freshness check at every 60 seconds, check_result_reaper_frequency at 60 and max_check_result_reaper_time at 90.

Hi Mark,
Thanks for the response. I just realized that I've opened the old

My freshness_treshhold is actually 600 (10mins), but still im seeing this
issue.

You have some interesting choices with your settings. If you have the
freshness and the reaper_frequency set to the same time of 60 seconds.The
freshness threshold is the time in which Nagios should consider a check to
be stale. This is done by looking at the last check's timestamp and
comparing it to the threshold you set (60 seconds). While the
reaper_frequency is the frequency in which Nagios will take all the
collected passive results and process them, which you also have set at 60
seconds. You are setting up a condition where most of your checks are
running close to stale and, given any processing time, with give you many
stale results.
Depending on your how powerful your system is, you will need to either
increase your freshness threshold (try 300 seconds), decrease the reaper
frequency, or do both. You may have to play around with the exact settings
that will work with your system and the number of checks you are performing.
I would recommend you start with increasing the freshness threshold.
Good Luck!

[Nagios-users] no used external command buffer slots
Hi, I have around 7362 incoming passive checks, and I'm trying to figure out a way how to get rid of stale check results by graphing with mrtg and working from there. I am under the impression that with these amount of passive checks, a generous number of external command buffer slots will be used. When I checked with nagiostats, it was zero. Could I be thinking wrong, or am I missing something?

I admint I don't know nagios that well, I started installing/using nagios
only recently, and I don't know where/how to start troubleshooting this. I
did install mrtg and did a good amount of trial and error with the config,

Re: [Nagios-users] lun monitoring
Andreas, I have absolutely *no clue* what you are talking about, this is the first email I sent for this month to nagios-users. I'm guilty on the other point you raised, I'm interested if there's nagios-users@lists.sourceforge.net something I can do to effectively measure how busy a lun is, e.g. is running an iostat against a lun and looking at %b as reliable as running it against a local disk. Nor am I anxious to let others solve my problems I've been reading and am currently reading some writeups on lun performance monitoring and I thought it wouldn't be a bad idea to throw a question onto this thread. I'm sorry if you saw it that way. On 2/3/09, Andreas Ericsson a...@op5.se wrote: Marc Ismael wrote: Hi, Anyone implemented any sort of lun monitoring plugin?

Re: [Nagios-users] lun monitoring
Thanks Russell, I've already got the path and target visibility monitoring covered. How about in terms of performance though? Is there value in monitoring io, e.g. via iostat or another utility?

execute the event_handler, passing the macros $SERVICESTATE$
$SERVICESTATETYPE$ $SERVICEATTEMPT$ $HOSTNAME$ as argument to
check_by_ssh.pl. But based on the log output above, these macros contain
'null'? i'm not sure why but im pretty sure macros are working since
$HOSTNAME$ was passed correctly.
Please give me a hint on what im missing.
Thanks,
Marc

[Nagios-users] how macros on event handlers work
Hi,
I'm slightly unsure about how i used event_handler in this situation
[Fri Apr 10 05:38:16 2009];Nagios 3.0.6 starting... (PID=1017)
[Fri Apr 10 05:38:16 2009];Local time is Fri Apr 10 05:38:16 EDT 2009
[Fri Apr 10 05:38:16 2009];LOG VERSION: 2.0
[Fri Apr 10 05:38:16 2009];Finished daemonizing... (New PID=1018)

[Fri Apr 10 05:51:16 2009];Warning: The results of service
'check_nagios_cronjob' on host 'remotehost' are stale by 0d 0h 3m 0s
(threshold=0d 0h 10m 0s). I'm forcing an immediate check of the service.
[Fri Apr 10 05:51:21 2009];SERVICE ALERT:
remotehost;check_nagios_cronjob;WARNING;HARD;1;WARNING: no information

}
define service{
use passive_template
service_description check_nagios_cronjob

freshness_treshold 600
}
define command{
command_namei_am_stale
command_line$USER1$/check_dummy 1 no information received from
passive check (stale)
}
based on the configuration above, im expecting a passive check to timeout
after 10 mins. Then check_command will kick in, but it just returns
WARNING which is HARD (i've set max_check_attempts to 1). it will then
execute the event_handler, passing the macros $SERVICESTATE$
$SERVICESTATETYPE$ $SERVICEATTEMPT$ $HOSTNAME$ as argument to
check_by_ssh.pl. But based on the log output above, these macros contain
'null'? i'm not sure why but im pretty sure macros are working since
$HOSTNAME$ was passed correctly.
Please give me a hint on what im missing.
Thanks,
Marc

Try stopping the Nagios daemon, make sure all instances of nagios are stopped (using ps -ef | grep nagios), and kill any which remain then start the Nagios daemon using /etc/init.d/nagios start .

I have a feeling that your check results are already stale before the reaper gets a chance to process them. tip: for a while, try setting max_check_result_file_age to 0 and see if you'd still get these errors. if not, then its a timing misconfiguration. cheers, Marc.I -- Stay on top of everything new and different, both inside and around Java (TM) technology - register by April 22, and save $200 on the JavaOne (SM) conference, June 2-5, 2009, San Francisco. 300 plus technical and hands-on sessions.
