Trying to add a switch, SNMP is turned on on the switch, community name is setup - when trying to add in Nagios Switch/Router Wizard, it gives me a "No ports were detected on the switch" error. It then says to run a cfgmaker command, I did and the link below is what I is what I received - It appears that it does see the switch and can connect to it. Not sure what to do next?

There is a known issue with the current switch wizard, and a new wizard has been posted at
http://assets.nagios.com/downloads/nagi ... switch.zip

Install through Admin -> Manage Wizards

Great Thanks, that allowed me to get past that and add the switch.

I am getting results though that do not make sense, when looking at Bandwidth, they are all reporting as:

OK - Current BW in: 0Mbps Out: 0Mbps

But I know that there is traffic moving on this switch - it is one of our busiest switches in the plant. Am I doing something wrong?

Thanks,
Marc

How long has it been since you configured this switch in XI? It may take a bit of time before you start seeing the results displayed for the first time.

Also, please run the following and post the results:

LC_ALL=C /usr/local/nagios/libexec/check_icmp -H 8.8.8.8
OK - 8.8.8.8: rta 72.236ms, lost 0%|rta=72.236ms;200.000;500.000;0; pl=0%;40;80;; rtmax=73.982ms;;;; rtmin=71.143ms;;;;

/usr/local/nagios/libexec/check_icmp -H 8.8.8.8
OK - 8.8.8.8: rta 77.177ms, lost 0%|rta=77.177ms;200.000;500.000;0; pl=0%;40;80;; rtmax=85.856ms;;;; rtmin=70.748ms;;;;

Looks OK to me...

It has only been a couple of hours - I will leave it and check it tomorrow morning. Thanks!

Great, I'll leave it open for a few days in case you still have issues.

Checked it again this morning - have setup two switches and neither of them are reporting any traffic on the bandwidth everything displays as:

OK - Current BW in: 0Mbps Out: 0Mbps

After installing the new wizard, did you rerun it (and re-add the hosts) as explained in the following document?

http://assets.nagios.com/downloads/nagi ... Router.pdf

using that pdf for adding Switches, my mrtg.cfg file does not contain any information for switches in it - this is all I see:

And I get all kinds of errors when I try to run LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg –check - and the errors are actually from different routers that we have at our sites - we used the WatchGuard wizard to add these, not the Switch/Router wizard and doesn't seem to display any errors for the switches we have added.
