Bandwidth usage per port

[glenlopez16]

Hi Nagios Support/Community,

I have a, I think a minor problem, but I'm hoping that nagios have this or anyone may recommend if it has a plugins or what.

So here's the scenario, after we configure, install the nagios, we monitor a router and it was successful. We see that it monitors the bandwidth per port and also showing the usage of bandwidth. My question is, is there any way to see the factors of each port or a granular detailed, I mean for example, who are the users using that port and showing the percentage of each user?

Any reply will be greatly appreciated.

Thanks a lot in advance.

Your device would have to support snmp oids/mibs for these metrics, or you would need to be able to run custom scripts on the device at minimum.

Hi,

Thanks for the reply.

But how would I do that? Can you give me a procedure or step-by-step procedures on how to do what you had recommended?

Thanks again.

Not necessarily a step-by-step due to this being hardware we likely do not use in house here, but we can help. What devices are you trying to check this on?

cisco Router

There are a very limited number of plugins on the exchange that may get you user statistics, but they are all for cisco wireless devices. You will need to contact the vendor (cisco) to get documentation on what metrics are supported through snmp. Then you will need to write a custom plugin script to check those OIDs/MIBs using snmpget. (You may be able to use snmp traps if the device supports them).

First and foremost though, you need to identify if the cisco device even supports the metrics you wish monitor through snmp. That is a conversation *you* must have with your vendor, or at the very least spend some time with your device's documentation.

Do you have further questions on this?

[glenlopez16]

I will post a follow up question here if there's any.

By the way thank you so much
