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:

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

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.
