Question

I have a postgres function that returns two columns

result, data
(int), (text)

If I run this command from postgres it returns the proper values and if I run it from the linux command line like this:

/usr/local/nagios/libexec/check_postgres.pl -H $HOSTADDRESS$ -u postgres -db monitordb –action=custom_query –critical=1 –query=”SELECT * from ops_get_status();”

It also return the proper values – at least it seems to and I don’t get any errors.

But when I insert it in the commands.cfg and watch this through the Nagios frontend
it return (null).

The log file doesn’t contain any detailed information for debugging this. So, what can I do to get to the bottom of this issue – any help greatly appreciated

I just had this same problem. Removing the semi-colon from the end of the query got it working.
