[Nagios-users] Switch Port Monitoring

[Robert Jackson]

Anyone like to share how they monitor switch ports?

I have a series of switches that I would like to monitor the ports for.
However
I would only want to see the overall switch as a host and the switch
ports as
host services.

Is this possible, anyone know how to do this?


Regards,
Rab.

Robert,

What I typically do is monitoring the switch with a PING, the I setup
services group(s). I have many switches that I watch gig0/1 as an
example as this is the port that interconnects all the other switches. I
have been grouping services groups based on the port that I monitor, and
then add the hosts/hostsgroups.

If you want to view ALL the ports, you can do that as well.

Check out the "check_snmp_int" command.

Mike

I use MRTG (which has the lovely benefit of exciting graphs) and then I
wrote a plugin that checks all of a host's RRD files (created by MRTG)
sequentially and compares them against a threshold.

Here, we use MRTG to graph the switch ports, and the routers2 frontend to
MRTG to make it pretty. Also, the routers2 frontend has a Nagios plugin to
allow the Nagios data to be displayed as well -- and a portstatus plugin to
show the current individual port configuration and status.

For Nagios, we use a simple ping service and then use the hostextinfo url to
link to the MRTG graphs page. On some switches, we also have a CPU use
service. We also have an SNMP trap service and the switches send SNMP traps
to the Nagios host which are parsed and relayed to the appropriate service.
Port up/down etc generate traps which can in turn generate alerts.

Finally, for key switch ports, and additional service can be defined for
that particular port status OID. It should be possible to do something
similar for port traffic thresholding, but we dont.
