I am getting following error while restarting the nagios3 service:
Error: Service check command 'check_pgactivity -U nagios_dispatcher -s bgwriter -w 80% -c 95%' specified in service 'check_pgactivity' for host 'localhost' not defined anywhere!

I have following entry in postgresql.cgf

define service {
host_name localhost
service_description check_pgactivity
check_command check_pgactivity -U nagios_dispatcher -s bgwriter -w 80% -c 95%
max_check_attempts 3
check_interval 3
retry_interval 3
check_period 24x7
}

I think you need a command definition like this:

Code: Select all

define command {
       command_name                  		check_pgactivity
       command_line                  		$USER1$/check_pgactivity $ARG1$
}

Then your service would be defined like:

Code: Select all

define service {
host_name localhost
service_description check_pgactivity
check_command check_pgactivity!-U nagios_dispatcher -s bgwriter -w 80% -c 95%
max_check_attempts 3
check_interval 3
retry_interval 3
check_period 24x7
}

I can restart the nagios service successfully after making the changes. Now the problem is I cannot see the service on OPM UI.

OPM isn't our product, so it's hard to say what the issue is. Your best bet is contacting them for support.

But, from OPM they are saying that it is the problem in Nagios end.
