SNMP plugin


I installed Nagios and trying to watch my printer status via SNMP
I downloaded check_snmp_printer version 3 from … ck/details.

My commands.cfg file:
define command{
command_name check_snmp_printer
command_line $USER1$/check_snmp_printer -H $HOSTADDRESS -C $ARG1$ -x $ARG2 -w $ARG3$ -c $ARG4$

printer.cfg looks like:
define service{
use generic-service
host_name hp1536dnf
service_description Toner Supply
check_command check_snmp_printer!!public!CONSUM!20!10

Nagios shows: WARNING: No SNMP response from -C! Make sure host is up and SNMP is configured properly.

Where is the problem?

SNMP works fine
snmpd is running

snmpwalk -v 1 -p works.
