Are you noticing a large influx of files in:
Yes, it happens all the time
That folder (in my case
/usr/local/nagios/var/spool/checkresults has 35 files with strange names, but all (except two) have a size of zero.

Or piling up in:
The only two folders on my filesystem named tmp are
/tmp and
/var/tmp and they are both empty...
Anyway, I've been doing some further analysis to log files and I've found out entries on syslog like:
Code: Select all
Feb 20 20:39:23 SRVCARTMSCORE01 ndo2db: Message sent to queue.
Feb 20 20:39:23 SRVCARTMSCORE01 ndo2db: Warning: queue send error, retrying...
That lead me to posts in other forums such as:
1 -
http://www.monitoring-portal.org/wbb/in ... adID=25673,
2 -
http://support.nagios.com/forum/viewtop ... 43&p=84026 and
3 -
http://support.nagios.com/wiki/index.ph ... 3.x_Issues
Rhey suggest that ndomod might unable Nagios' to do its work.
while 1st post just suggests downgrading NDOUtils,
Posts 1 and 2 suggest it has something to do with settings on
/etc/sysctl.conf, but I'm not comfortable enough to do those changes without understanding them

Run the following commands and show us the output:
Code: Select all
grep "for i in" /etc/init.d/nagios
cat /etc/sysctl.conf

With further investigation of syslog and consultation of NDOUtils README file, I've defined the following values:
Code: Select all
root@myServer:~# sysctl -p
# msgmnb - product of (msgmax * msgmni )
kernel.msgmnb = 393740288
# msgmax - suggested by NDOUtils README file
kernel.msgmax = 65536
# msgmni - left as it was
kernel.msgmni = 6008
So far I've detected no ndomod error/warning messages on syslog. And the servicechecks seem to be synched
.
Yet, I want to observe teh server's behaviour for a few days prior to closing this post.

The kernel queue values have definitely solved those errors I was facing.
I do not recall how to set as solved, but I've marked it with a [v] for success
Thank you all for the time and knowledge shared.
This post will serve as knowlege article for my future implmenmtations
