psql -c COMMAND DATABASE

executes COMMAND using DATABASE and displays the results without starting psql interactively.

I'm not familiar with Nagios, but you should be able to do something
like

psql -tc 'select 1' database

to see if it's alive and accepting queries.

Is anyone using Nagios to monitor PostgreSQL?

If so, is there any way to check for more than just your PostgreSQL

instance

being up?

This weekend, we had an issue where a database shutdown failed due to a
rogue query that would not die w/o a kill -9 being done on it. The

database

remained up and accepted connections only to tell the connection to go

away

because the database was shutting down.

This up and accepting connections caused our Nagios instance to not report
the database being down.

Any ideas on how to get around this?

Thanks,

Chris
