2012R1.3 Update Stops MRTG

Posted: Sat Feb 02, 2013 3:32 pm

After an update to 2012R1.3 MRTG has stopped updating files in /var/lib/mrtg. Since the 2012R1.3 update the machine has been updated to the latest version.

The mrtg.ok file is listed as the others at Jan 20. There are 3212 files of Jan. 20 and 9 files updated to Feb. 2.

Code: Select all

-rw-r--r--. 1 root root      0 Jan 20 09:52 mrtg.ok
Cron job for mrtg is working.

Of the bandwidth checks 900 are saying the rrd file does not exist. Of the ones that do exist they are all saying 0 bandwidth. Perfdata files in /usr/local/nagios/share/perfdata are being updated.
rrdcached has been turned off for trouble shooting with no joy.

Here is the npcd.log

I found the problem. Once the update was complete there was an additional issue where the /var/lock/mrtg directory was filled with lock files, thousands of them. Though it did not show in logs the lock files stopped the system from being able to process MRTG. Once the lock files were removed the system began to recover. This system was under a heavy load at the time of the update so that certainly was more of the issue than the update.

The problem has happened again. Two issues:

1. All but 15 out of 4500 rrd files are NOT getting updated
2. All Bandwidth is 0

I have turned off all performance enhancements for rrdcached and npcd and that did not make a difference.

It looks like lock files are out of date and not getting removed. The date on the CentOS server is up to date, using NTP.

LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lock/mrtg/mrtg_l --confcache-file /var/lib/mrtg/mrtg.ok
2013-02-04 07:33:48: ERROR: I guess another mrtg is running. A lockfile (/var/lock/mrtg/mrtg_l) aged
227 seconds is hanging around. If you are sure that no other mrtg
is running you can remove the lockfile

If I removed lock files and run the command here is the output....many lines like this:
LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lock/mrtg/mrtg_l --confcache-file /var/lib/mrtg/mrtg.ok

2013-02-04 00:07:26: ERROR: Target[192.168.5.1][_OUT_] ' $target->[3089]{$mode} ' did not eval into defined data

Lock files appear again.

Mike, does the lock file appear and then not go away on subsequent runs?

Re: 2012R1.3 Update Stops MRTG

Yes every time lock files appear and are not removed

Does mrtg appear to continue to run?

Code: Select all

ps -ef|grep mrtg
Also, just curious, is this a large mrtg.cfg or just a small one?

Can we confirm what version of mrtg you are running on this machine

Code: Select all

LANG=C LC_ALL=C /usr/bin/mrtg

No it would not run. So I finally fixed it .....had to edit the 200,000 line mrtg file and remove errors that occurred. The key to finding the solution was running the mrtg command that cron uses and solving any issues that resulted. Anyway it is fixed and has been running good for several hours. Thanks.
