Nagios Support Forum

I have installed and configured check_pgactivity. But no PostgreSQL Service is showing on OPM UI. I have contacted with OPM Support they are saying that the problem is on Nagios end.

I have added following lines in command.cgf

define command {
command_name check_pgactivity
command_line $USER1$/check_pgactivity --service bgwriter -U nagios_dispatcher -h $HOSTADDRESS$ $_SERVICEOPTION_THRESHOLD$
}

and following lines in services_nagios2.cfg

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
notification_interval 5
notification_period 24x7
}

I am using ubuntu 14.04.

Are you able to test the command over the CLI, to get it working to your needs? Then, show us the full input / output so we can help to see how the check should be running.

It looks like you're overlapping, which could be causing issues. Could you show us a screenshot of what the status is reporting?
But, you're passing -U nagios_dispatcher in $ARG1$ of your check_command - Additionally, your command_line doesn't have any way to pass $ARG1$, might want to modify it to something like below (also depends what $_SERVICEOPTION_THRESHOLD is set to, I don't see you setting that variable at all) -

Here are the input and output.
root@giles-S451LA:/usr/lib/nagios/plugins# ./check_pgactivity --service bgwriter -U nagios_dispatcher -h $HOSTADDRESS$ $_SERVICEOPTION_THRESHOLD$
CHECK_PGACTIVITY UNKNOWN: Query fail !

bash: !-U: event not found
root@giles-S451LA:/usr/lib/nagios/plugins#

Your tests at the command line will require the values like $HOSTADDRESS$ to be replaced with the actual values like xxx.xxx.xxx.xxx

It looks like the plugin is requiring a password, this isn't standard with Nagios plugins - do you know why it's asking?

In this other forum post you created for the issue, https://support.nagios.com/forum/viewto ... 56#p193556 - it looks to be resolved, but the data isn't appearing in OPM. We did not write OPM so it's hard to know how they're pulling information.

I have no idea why it is asking for password.

OK, you can close the following issue.

Can you post the entire check_pgactivity plugin for us to look at?

How can I post the entire check_pgactivity plugin here?

You should be able to upload it as an attachment. You may need to add .txt to the extension for it to work.
