Problem with service monitoring

This morning we had an activity on our Nagios server, whereby we inserted new disks into the server, and rebooted the server.

The disk implementation failed, therefore we had to revoke the changes, and rebooted the server once again.

The server was up and running at 6:00 am this morning. However, after 2 hours, the nagios monitoring does not show any data (percentage of usage, etc for the services like cpu, memory, disk, etc).

What could be the problem, and how do we resolve this?

Did you checked if your filesystem is in readonly mode? The first I can think of.
Did you check for system logs and nagios logs?

Take a look here for more possible reasons.

Hi,

If you've rebooted the server, chances are that nagios doesn't have a start script in position in the "/etc/rc........" directory.

You can start manually using;

Code:
/usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg
