Hello @d3rek,

Have you verified that your configuration is valid before trying to start Nagios Core? You can verify this via the command line with

Code: Select all

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

You can also check the Nagios Core logs located at /usr/local/nagios/var/nagios.log

I hope that helps!

[d3rek]

Thank you bbahn.
I verified my configuration and it looked fine.
So i looked into the .log and found:

Interesting enough it didn't get the "caught SIGTERM, shutting down" on the last try where it just stopped.
I looked into another topic from 27.may.15 and i don't have any brokers installed but i don't know where to find the init.d script.
I looked in the init.d directory but i didn't see any skript for nagios.

is any of these entries the init.d skript?
Or maybe there is another method to fix this problem

@d3rek, I don't think Nagios Core has had an init.d script in a while and I'm not really sure what your issue is. If you would like more in-depth support, you can create a ticket at https://answerhub.nagios.com/support/s/
