Hi Support,

The Nagios XI Graph is not working again...
Need help on this...

Appreciate for your help.

Sorry we missed you - our support is from 9AM to 5PM CDT so posts outside of that range will have a bit of a delay in response.

What version of XI are you using? Do you have a lot of perfdata files piling up? What's the system load?

Code: Select all

ls -l /usr/local/nagios/var/spool/perfdata/
ls -l /usr/local/nagios/var/spool/xidpe/
w | head -1

Hi,
My Nagios XI version is "Nagios XI 2014R1.4"

[root@localhost ~]# ls -l /usr/local/nagios/var/spool/perfdata/
total 0
[root@localhost ~]# ls -l /usr/local/nagios/var/spool/xidpe/
total 0
[root@localhost ~]# w | head -1
10:58:38 up 11:12, 1 user, load average: 0.52, 0.49, 0.46

I did a reboot on the Nagios XI server yesterday, seem like the graph is back to normal.
May I know, anyway I can prevent this to happen again? or how to troubleshoot it if happen again?

I'm currently playing with some ideas on adding extra services to localhost so we can catch these things before they become an issue.

I don't have anything concrete yet however I suggest adding some services that:

• check to make sure the npcd service is running
  Doing a file count of /usr/local/nagios/var/spool/perfdata/ to make sure it's not filling up
  Doing a file count of /usr/local/nagios/var/spool/xidpe/ to make sure it's not filling up

My current npcd service is running.

I believe troy was simply mentioning adding these additional checks simply to help alert when this may be an issue. It sounds to me like you may not have npcd set to start automatically. Let's try adding it, and see if that helps on next reboot. Otherwise we will likely have to grab /var/log/messages right after a reboot to see whats happening with the npcd service. Try running:

chkconfig --add npcd

I added the npcd services and turn on start automatically after reboot..
Thanks for your support..

I am glad your issue has been resolved! I am locking this post.
