monitor network card/interface

[mirgo]

Hello

Is there a way in Nagios XI to monitor network card/interface via SNMP. The best solution would be to one of the configurations wizards (like windows and linux SNMP) or there is a way to create a new template based on those SNMP wizards and add network card to to it, so that if you add a host then it monitors disk, cpu, ram AND network too. And also when the check is added, it creates graphs based on upload/download.

Thank you!

Do you have an OID available for that data? If so, then it should be possible.

Otherwise, for Windows, I've helped customers get setup by monitoring the data through performance monitor. On Linux, there are a few plugins that will check the network interface statistics and report back.

Isnt the OID standard for most network cards? Question is how to add that check or extra network interface nagios check to an already existing configuration wizard, so i don't need to define network check separately from the rest of the linux/windows SNMP check(disk, cpu, ram, etc).

The plugin that is included on the XI server requires running the Wizard to create MRTG rrd files so it can not be used in a template.
You could use an alternate plugin that doesn't need the rrd file and use that instead.
Take a look at the link below and see if that would work for you.

If you wanted to monitor the status and the bandwidth of a network card, you could run the "Network Switch / Router" wizard against the Windows/Linux box. You will see the interface in step 2 of the wizard. If you used the EXACT same hostname as an existing host, the wizard will simply add two additional services to the host (Port x Status & Port x Bandwidth).

Possible scenario:
1. You run the SNMP wizard against a Linux host.
2. You run the Switch wizard against the same host (use the same hostname in step 2)
3. You will notice that the switch wizard added two new services to the existing host (set up in step 1)

Hope this helps.

So there are 2 ways, either add via check like check_iftraffic64 or add by Network Switch / Router and there is no way to combine those to a wizard or a template that monitors whole server.
We have a lot of hosts to migrate and it would be a lot easier to add all the checks at once with each host. Is that something you plan to add in the future? Because graphs are one of the selling points going from Core to XI and you probably agree that you need to have overview of your network card traffic.

I filed an internal feature request for adding the network card checks (status & bandwidth) to both, the Linux and Windows SNMP monitoring wizards (TASK ID 9558). Let me know if it is all right to lock this topic. Thank you!

Looking forward to seeing that feature in the next releases. You can lock the topic. Thank you!
