I think at this point I may back-out the changes that were sending information to ramdisk for perfdata... it seems to be the underlying cause.

Are we sure they are being reaped? 900000+ files . .. .

things are just getting stranger now- I realized that the command to mv was incorrect and sourcing a file that was not there, so upon changing to:

process-host-perfdata-file-bulk

Code: Select all

/bin/mv /ramdisk/spool/host-perfdata /ramdisk/spool/xidpe/$TIMET$.perfdata.host

and applying this configuration, files are being created in /ramdisk/spool/xidpe on a regular basis.

but now I see the following issues:

in npcd.log:

Code: Select all

/ramdisk/spool/perfdata//host-perfdata.1362511776 does not exist.

as well, all of my service checks are updating but nagios has them listed as pending when I drill down to the service check, and none of the nodes are showing their services listed under them.

I've tried doing a full shutdown and restart of nagios processes, but it's so far proven unsuccessful in getting back to a stable state.

trying to run the process by command line:

Code: Select all

Check/fix the permissions for the perfdata folder:

Code: Select all

chmod -R +x /usr/local/nagios/share/perfdata

Also, take a look at the /usr/local/nagios/var directory, and make sure everything is owned nagios.nagios, and permissions are at least 0664 on all files.

permissions all look fine. I upped the timeout on the process_perfdata.pl script- looks like it is chomping on it for a while, and timesout:

Code: Select all

10974 nagios    17   0  127m 5332 2428 R 96.2  0.0   3:05.18 process_perfdat

I upped the timeout to 1600 seconds to see if it will go through it, but the file it's processing is rather large, assuming it would take a while:

Code: Select all

-rw-r--r-- 1 nagios nagios 235M Mar  5 15:43 host-perfdata.1362511776

Posted: **Tue Mar 05, 2013 4:41 pm**

hmmm. That seems excessively large.

Posted: **Tue Mar 05, 2013 4:58 pm**

looks good now- I did a reboot, cleared the ramdisk of prior data, and am now seeing data- I think there was just too much for it to handle.

Posted: **Tue Mar 05, 2013 5:15 pm**

Sounds good. You should watch the number and size of files that collect there. They *should* get reaped fairly quickly.
