[mrtg] Re: MRTG and PacketShaper.

[MRTG]

I have finally gotten MRTG to work with the PacketShaper. But the usefulness
of the results is well below the native reporting capabilities of the device
itself. The PacketShaper continuously logs and reports instantaneous peak
and average traffic (in bits per second) for every traffic class, and that
is something MRTG is unable to "see" through 5-minute polls.

MRTG captures total bytes traffic every 5-minutes (or more) and subtracts
previous reading from the current one and figures out bandwidth utilization
(hence the denomination 5-minute average for the daily graph). While the
figures reported by MRTG are realistic, they do not tell the whole story
(e.g. what happened during that 5-minute gap between polls, nor does it show
the all important traffic "peaks" being generated by bursty applications).

If anyone is interested in the config file, I'd be more that happy to share
it with them.

Since the error doesn't correspond to the config, I'm not sure what
to tell you.  The error complains about  ip address 195.14.153.202,
yet that is not in your config.  Do you have more than one config
file?

Here is my mrtg.cfg file:

I am in Windows environment, and MRTG runs as a service using FireDaemon.

Paul,

Thank you for the tips. Based on what your suggestions, we are making
progress, but we are not quite there yet.

We have corrected the OIDs to two per graph with an & in between, MRTG does
not seem to complain about that aspect any more, the error message now reads
as copied below:

The name specified is not recognized as an
internal or external command, operable program or batch file.
WARNING: rateup died from Signal 0
 with Exit Value 1 when doing router '195.14.153.202_1'
 Signal was 0, Returncode was 1
The name specified is not recognized as an
internal or external command, operable program or batch file.
WARNING: rateup died from Signal 0
 with Exit Value 1 when doing router '195.14.153.202_2'
 Signal was 0, Returncode was 1

Other than putting two (valid) OIDs per graph and removing the loadmibs
commands, the mrtg.cfg file is essentially unchanged.

What could be causing the above error messages?

Thank you for your assistance.

George Jahchan
