I am trying to use "check_snmp" command to monitor bandwidth on a Cisco Catalyst 3560G switch. The command I am using is: check_snmp! -H 10.10.10.31 -C slpub -v 2c -n GigabitEthernet0/3 -d 5 -k -w 0,0 -c 0,0. When running the verification command (nagios -v /etc/nagios/nagios.cfg) I don't receive any errors but on the Nagios web interface I am receiving the following message in the "status information" field: Usage:check_snmp -H <ip_address> -o <OID> [-w warn_range] [-c crit_range].
Does anyone have any clue as to what needs to be in the configuration file to be able to monitor switch interface traffic?
