Nagios Support Forum

It is a combination of things. We recently Yum updated the box - which looks to be around the time that charting stopped. We also updated froom 2014R1.3 to 2.3 yesterday, noticed that they weren't working, and then saw that 2.4 was released so upgraded this morning to 2.4 to see if that helps, but it didn't. Both Test and Prod are not working now.

Both are CentOS 6.6/64bit, running 2014R2.4 XI (attached prod system profile) Test was a deployed VM, and prod was a custom install to match test.. Or close to it.)

Looks like /usr/local/nagios/share/perfdata RRDs are not updating.

Ran basic troubleshooting from http://support.nagios.com/wiki/index.ph ... leshooting

cat /usr/local/nagios/etc/pnp/process_perfdata.cfg |grep LOG_LEVEL
LOG_LEVEL = 2

ATTACHED /usr/local/nagios/var/perfdata.log (from test and prod)

cat /usr/local/nagios/etc/pnp/npcd.cfg |grep log_level
log_level = -1

ATTACHED /usr/local/nagios/var/npcd.log from both


tail -50 /usr/local/nagios/var/perfdata.log | grep TIMEOUT --> NONE

tail -50 /usr/local/nagios/var/npcd.log | grep "MAX load reached" --> NONE

Ran /usr/local/nagiosxi/scripts/reset_config_perms

touched /var/lock/mrtg for the fun of it. nothing.

[root@ust-nagios1p /]# ls /usr/local/nagios/var/spool/xidpe | wc -l
2

[root@ust-nagios1p /]# ls /usr/local/nagios/var/spool/perfdata | wc -l
2

ls /usr/local/nagios/var/spool/checkresults | wc -l
0

tried disabling HighCharts for perfdata as per another random charting topic in the forum and that didn't work.

EDIT: removed prod-profile.zip

Can you run the following commands and show us the output?
Have you tried deleting the RRDs and XMLs for one of your hosts/services to see if they are going to be recreated and the graphs will appear? You can also set up a new host, wait for 15-20 min and check to see if perf graphs are available.

When I remove the .rrd from /usr/local/nagios/share/perfdata - it will recreate them new, but then never update them again. I removed a couple from the test system, and then added a whole new server and it had the same results. Here are your other commands. Thx.

Ok, being you are using rrdcached, what are the settings for the flush time? The graphs will not update until the rrdcached flush time is reached.

[root@ust-nagios1t ~]# cat /etc/sysconfig/rrdcached
OPTIONS="-s nagios -m 0660 -l unix:/var/rrdtool/rrdcached/rrdcached.sock -F -w 900 -z 90 -j /tmp/ -b /var/rrdtool/rrdcached -P FLUSH,PENDING"
RRDC_USER=nagios

Do you have a "rrd.journal" file in the "/tmp" directory and what is the timestamp on it? Is it updating every 15 min?

looks like they are updating hourly.

[root@ust-nagios1t ~]# ll /tmp | grep journal
-rw-r--r-- 1 nagios users 0 Jan 27 12:06 rrd.journal.1422382000.586888
-rw-r--r-- 1 nagios users 0 Jan 27 13:06 rrd.journal.1422385600.586905
[root@ust-nagios1t ~]#


[root@ust-nagios1p ~]# ll /tmp | grep journal
-rw-r--r-- 1 nagios users 0 Jan 27 12:48 rrd.journal.1422384501.504505
-rw-r--r-- 1 nagios users 0 Jan 27 13:48 rrd.journal.1422388101.504521

The journal file gets updated every 3600 seconds(default) so that you don't loose rrd data when the system is shutdown. Every 15 minutes the rrdcache gets flushed to disk (-w 900).

It is weird your journal files are empty...

A couple more things, lets run

For test - and Prod. Both don't work. I do remember an upgrade or 2 before some charting issues and I ran some command to find the "actual" rrd cache as per some other Forum and changed the path in prod and that fixed it back then. (just a little historical info) Looks like the pid on both systems is when it stopped working.
