Hi, i use mrtg to monitor some bandwidth interfaces of switches, my question is, nagiosgraph can monitor it too?, can monitor optic fibre?, And where can i find some webpage to install and configure nagiosgraph for ubuntu?, Very Thanks

Nagiosgraph will just generate graphs for reported performance data. You will need a plugin to check and report performance data for bandwidth, and as you are using mrtg, it should be able to.

Top hit on google:
https://raymii.org/s/tutorials/Nagios_C ... 12.04.html

but for example, in the nagios web interface in one switch i am monitoring interfaces services, like (Port 5 Bandwidth), with the check_mrtgtraf command, nagiosgraph can graph this services like mrtg?

Yes, as long as it returns valid performance data. Can you post the performance data reported for the check?

How to performance data?

Performance data is listed in the Nagios Core interface on the relevant service details page - third row from the the top of the "Service State Information" table.

For now the interfaces monitoring are disable, but the performance data showed me like "check_local_mrtgtraf: OK, and the bits up and down oming from the interfaces, like "in: 267b/s out: 123 b/s

That sounds like status output, not performance data output. Can you take a screenshot of the details page for one of these bandwidth checks?

You mean in the Services menu?,

this is one part, now its not monitoring the switch its this because the mibs error, or where is the part of information that you told me

Well, mrtg has not updated the relevant rrd in a very long time. So I doubt you currently have performance data for it. Did you configure a cron for mrtg? See: http://serverfault.com/questions/215705 ... using-mrtg
Also, I requested a screenshot of the status details page for the bandwidth service, but you need to correct the issue with the mrtg cron before that bit is relevant.
