Always i have: check_mrtgtraf: Impossible d’ouvrir le fichier de log de MRTG
In the configuration of switch I have:
check_command check_local_mrtgtraf!/var/lib/mrtg/192.168.1.253_1.log!AVG!1000000,1000000!5000000,5000000!10
but in var/lib/mrtg i don’t have a file 192.168.1.253_1.log

It's simple enough for the first 24 ports, but my 2950 then has two more ports labelled 1 and 2 (ie duplicating the first 2 port numbers). If I use snmpwalk to see what ports are being monitored, I get 28 in all: # snmpwalk -v1 -c public my_switch -m ALL .1 | grep ifOperStatus RFC1213-MIB::ifOperStatus.1 = INTEGER: down(2) RFC1213-MIB::ifOperStatus.2 = INTEGER: down(2) RFC1213-MIB::ifOperStatus.3 = INTEGER: down(2) ... RFC1213-MIB::ifOperStatus.26 = INTEGER: down(2) RFC1213-MIB::ifOperStatus.27 = INTEGER: up(1) RFC1213-MIB::ifOperStatus.28 = INTEGER: up(1) I've not been able to find this information from the usual sources (ie Google, Cisco).

Does anyone have an idea on making smth like subservices in Nagios. A.e. I need to monitor the throughput on each port of the switch and each port status. I wrote a small script using snmpwalk command, that gives a list of ports and their status(or anything that snmpwalk shows) as a result. And I dont't even imagine how to make Nagios understand it in this way: host -> service(my script) -> port(as a result of the previous) -> smth I choose from snmpwalk Thanx Hy guys!

The cisco plugin that Ramesh linked to looks good, but I'm using Enterasys equipment. Is anyone aware of any ways to monitor switch stacks via snmp? Cheers, Cameron Hi Guys,

I’m interested in monitoring a switch stack (echoing Jeremy’s question above). The cisco plugin that Ramesh linked to looks good, but I’m using Enterasys equipment.

Is anyone aware of any ways to monitor switch stacks via snmp?

@Jeremy,

If you are using cisco switches, Check-out check_cisco.pl Nagios Pluginfound in the Nagios Exchange that seems to monitor the ports that are part of the multiple stacked switches.
