Is the nagios process running?

Code: Select all

service nagios status
ps -ef | grep bin/nagios

Where is it showing that notifications are disabled? Please provide a screenshot.

It looks like mysql may not be running.

Code: Select all

service mysqld status
service mysqld start

Then let's attempt to tail the error log...

Code: Select all

tail -n100 /var/log/mysqld.log

Please report the above back. Thank you!
