Try setting the debug level on and then restart Nagios.

Code: Select all

sed -i 's/.*debug_level=.*/debug_level=-1/g' /usr/local/nagios/etc/nagios.cfg
service nagios restart

Now you can tail the debug log and see what is happening just before every "Caught SIGHUP" message.

Code: Select all

tail -f /usr/local/nagios/var/nagios.debug

I dont understand why that is restarting. Please help me to understand why the restart is happening. Sorry i was new and learning nagios. i have the basic level knowledge of Nagios like configuring the hosts and all. So please excuse me and help me in this.Thanks.

[abrist]

Do you have any event handlers in use with this server that may cause a restart of the nagios process?
Do you use nconf/nagiosql? (The apply config button forces a restart)
