start up nagios and get error in the log

[ducle99]

When I start up nagios, I got this error in the nagios log file
Failed to connect to query socket '/usr/local/nagios/var/rw/nagios.qh': connect() failed: Connection refused

nagios 4.0.2 is running on Solaris 11.

Can you post your nagios.cfg file please.

Also run this command and post the output:

Code: Select all

ll /usr/local/nagios/var/

Stop nagios, get a listing of the rw folder, and then start nagios and get another listing. Post the results here:

Code: Select all

service nagios stop
ls -la /usr/local/nagios/var/rw
service nagios start
ls -la /usr/local/nagios/var/rw

It looks like the nagios.cmd is being left behind when nagios stops so I suspect we need to delete it so it is correctly started. There may also be more than instance of nagios running which can cause this.

Run this:

Code: Select all

service nagios stop

Then this:

Code: Select all

ps -aef | grep nagios.cfg

If you get any results for this (except for the grep result) you will need to kill those PID's

Code: Select all

kill PID

Where PID is the PID number from the last command.

Now run this:

Code: Select all

rm -f /usr/local/nagios/var/rw/nagios.cmd
service nagios start

Does this fix your problem?

Can you also post the output of this after running all those commands:

Code: Select all

ls -l /usr/local/nagios/var/rw

I followed all steps, but the same error still show up in the logs.

I updated the nagios.cfg for the following entry
check_external_commands=1
and add the Apache user account to the nagios group.
When I restart nagios, the error is gone.
Thanks for your help.

Have a good one. Locking.
