I'm using the following service to monitor our postgres db from nagios:

define service{
       use                             test-service         ; Name of servi$
       host_name                       DEMOCGN002
       service_description             Postgres State
       check_command                   check_nrpe!check_pgsql!192.168.1.135!test!test!test
       notifications_enabled           1
       }

On the remote machine I've configured the command:

command[check_pgsql]=/usr/lib/nagios/plugins/check_pgsql -H $ARG1$ -d $ARG2$ -l $ARG3$ -p $ARG4$

In the syslog I can see that command is executed, but there is only one argument transmitted:

Oct 20 13:18:43 DEMOSRV01 nrpe[1033]: Running command: /usr/lib/nagios/plugins/check_pgsql -H 192.168.1.134 -d  -l  -p

Why are arguments 2,3 and 4 missing?
