Nagios Component Status Issue

[ilanabilah]

Hi all,

Can help me with below issue :

1. Performance Grapher component is not running. what need to check to bring it up?

2. Have anyone experienced in intermittent on the component status. it was observerd from NagiosXI > Admin, and it shows the first three component status keep on intermittent (OK and NOTOK) within few seconds. please find attachment below.

3. It takes long time to apply configuration from Nagios Portal, however, no issue when reconfigure_nagios through Nagios Core.

your advice are much appreciated.

1. You should just be able to click on the gear icon and click Start or Restart, and it should come back up. If it's not coming up, you can ssh into Nagios, and run systemctl status npcd, and that should give us a clue as to why it isn't working.

2. The intermittent OK/NOTOK seems a little odd. Are there many people administering Nagios? Could they be related to someone else restarting Nagios Core?

3. This may be related to how large your configuration is. When you restart Nagios Core, the daemon is just stopping, starting, and reading the configuration files. When you apply configuration in the portal, it re-writes all of the configuration files as well. This shouldn't take terribly long, but this can vary depending on the size of configuration, and the hardware resources Nagios has to work with.
