Current version of Nagios xi: xi-5.6.14

After CentOS yum updated, NagiosXI seems not working. I find that there are some components that stop running. I think there is missing ndo2db service after the yum update. May I know how to troubleshoot it? Many thanks.

Reinstall ndo:

Thanks for your great help. I just restall the subcomponents and resolve both errors of performance grapher and database backend. However, the monitoring engine seems still cannot be running. May I know how to resolve it?

[root@nagiosxi /]# service nagios status

After reinstall ndo, database backend and performance grapher are running with no error, however, the monitoring engine is still not running. Please advise?

Try starting it with:
This will usually give us some more info to work with if it crashes.

It seems running normally after I restored the snapshot. Many thanks.
