[mrtg] Re: MRTG Issues

[Koelstra, J. (Jan)]

Tracy,

Some answers:

To 1) Have you considered the possibility of non-routed traffic like broadcast traffic?

To 2), 3) and 4) If you use cisco equipment the interface numbers you get from an snmwalk are not fixed. When a Cisco router is reconfigured the numbers can shift. They can stay the same after an reconfiguartion but shift after the next restart of the box. A remedy against this is to use '--ifref=descr' or '--ifref=name' in your cfgmaker command. See the cfgmaker documentation for more details on '--ifref'
At the moment I suspect you are looking at the wrong interface.

About the WARNING: Each target has it's own .log and .old file. Inside the data is stored needed for creating the graphs. If these files do not exist MRTG will  give the warning message, and then create the files

Hth,

Jan.

Subject: [mrtg] MRTG Issues


I have inconsistencies in the graphs.  The graphs do not correlate with our router.

1)  Adapter E1 shows about zero traffic during off hours, while S0 shows a fair amount - about 400K - continuing all the time.  This should show up in E1 since all traffic into the router is going to the LAN.
2)  "In" and "out" figures appear to be reversed from "show int" on the router.
3)  "In" and "out" figures don't correlate with the numbers from "show int."
4)  As of Wed. at 3:15, the graph for S1 shows zero traffic either way, while show int says it has a lot of traffic.

I receive this message when MRTG is started.

There are also two error messages in Event Viewer.
