Switch Port Monitoring Advice

[Robert Jackson]

What I don't understanding, at the moment, is do I have to setup each of the 
ports as an individual host? Obviously the check_host_alive would check the
switch itself is online and would not really be relevant to each of the ports.

I was thinking of some kind of Link Status service, where I could pass a port
number or group of port numbers, and get a status returned.

In terms of 3Com switches, I see quite a lot of Cisco specific scripts and was
wondering if anyone had done anything with 3Com switches. In particular I
was interested in the uplink ports and traffic throughput.


Regards,
Rab.

Hi,

Monitoring switch ports is in much case useless as you often monitor the
servers behind. 
In case you want to do this, and test the traffic flow through them, I think
the best way is to use snmmp and group the testing of ports in a few (or
one) services to minimize snmp queries, and only select the ports which
should be up (and/or test other ports to be down).

About 3COM Superstack switches, what do you exactly want to monitor ? Did
you look in www.nagiosexchange.org or specific to snmp
http://nagios.manubulon.com ?

Regards,

Patrick

I'm currently in the process of setting up Nagios to monitor our internal
network. 
As part of this process, I want to monitor switch ports and probably make
them the parent of the device connected to them.

What is the best way of going about monitoring switch ports? In particular,
if the individual ports have to be set-up as a host (?), the
check_host_alive script (used for normal hosts) surely is not relevant? I
really want to check specific ports are enabled, up and traffic is flowing
to/from them. Does this mean that I only want to monitor the ports I have
purposely enabled and don't bother monitoring the ones not enabled?

Rab.
