[mrtg] Re: Values less than real

[Koelstra, J. (Jan)]

You did run into the limits of 32bit counters. (approx. 114Mbit per 5 minutes interval)

To resolve this you can poll the 64bit counters. For details have look at http://people.ee.ethz.ch/~oetiker/webtools/mrtg/mrtg-reference.html and search for version.

An other hint: by adding "bits" at your option line you can leave out the "*8" in your target line and also omit the 4 Legend lines.


Hth,

Jan.

Subject: [mrtg] Values less than real


Dear All,




I am monitoring Cisco Router 7206 with 2 Giga Interfaces ,

One Giga interface gives me values less  than real while the other giga interface gives me real values

The interface that gives me right values its traffic pattern between ( 40 Mega --> 60 Mega bps)

While the wrong one its traffic pattern between ( 170 Mega --> 200 Mega bps )
