Hi,

The performance graphs on my system stopped updating on 09/07/2012. We did get a key to extend our software trial last week also. Would that effect the graphs?

Thanks,
Tom

No, it shouldn't, but try the following solution and see if it applies to your situation.

Also, make sure the performance graphing service is running ok.

mguthrie,

Thanks for getting back to me. I have tried restarting the npcd service several times and I ran the script to reset the perms. Here's the output from the command that you pointed to me to:

[root@nagiosxi ~]# cd /usr/local/nagios/var/spool/xidpe
[root@nagiosxi xidpe]# ls -f | wc -l
2

Is your CPU load over 10.0 by chance?

Do you get and recent error messages when tailing the following log files?

tail -f /usr/local/nagios/var/npcd.log is constantly updating. Here's the output from the tail -f /usr/local/nagios/var/perfdata.log:

mguthrie,

The performance graphs appear to be slowly populating now. The system load is at 0.67 but the I/O wait time is at 63.30.

Did the performance graphs update? Is the issue resolved?

Well... the performance graphs are up to date now. Thanks. But, now the server statistics are not updating. Should I start another post for that issue?

Lets run to following to make sure that cron is listed

Here's the output:

[root@nagiosxi ~]# ps -ef |grep sysstat.php
root 22513 22246 1 13:04 pts/0 00:00:00 grep sysstat.php
