recently installed nagios and discovered my edge router X. I get the bandwidth but not the total up / down bytes.

any ideas?

Hello mjr2015,

Which version of Nagios XI have you deployed. You'll find the version number in the lower left corner of the home screen. And are you saying that all of your bandwidth checks are returning 0 in and out on all of your ports? If so, and you're running version 5.5.7 or 5.5.8, it's most likely a permissions issue. Running the following commands from a console or terminal session on your Nagios XI server will resolve the issue:

Code: Select all

chown "apache:nagios" /etc/mrtg -R
chmod 775 /etc/mrtg -R
chown "apache:nagios" /var/lib/mrtg -R
chmod 775 /var/lib/mrtg -R

10 minutes after running these commands you should see bandwidth data. Let us know if this resolves your issue.

Thank you!

In addition to what @ bolson said - how did you create your check? Did you run our Network Switch / Router wizard? If you did, you should be able to see "in" and "out" Mb/s (last, avg, and max).

I'm sorry I thought the forum would generate an email when responded to.. i guess not!

but I am running 5.5.8 and I ran the suggested above commands however those users don't exist on my machine

I ran the wizard. It still reports 0

When you say the following what exactly do you mean?

The Network Switch/Router wizard only produces the bandwidth, not total bytes across the interface.
