Nagios Support Forum

Operating System = CentOS 7.2.1511 (core)
Running virtual (Hyper V)
Nagios Version: 4.0.8
Nagios Plugins: 2.0.3
64-bit systems

I rebooted the server and the dashboard shows that the Monitoring Engine is off and it will not start. On the server, Nagios is running, but with errors. Screenshots of both attached.

The research that I've done has not provided many results at all. If anyone could provide some input, I would greatly appreciate it.

Thank you.

Can you login to the server as root, run the following to see is the nagios daemon starts.

Code: Select all

service nagios stop
killall -9 nagios
service nagios start

If this still fails, please run the following and post the output.

Code: Select all

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
ps -ef --cols=300
df -h
df -i
