[mrtg] Re: How to measure Network Utilisation Percentage in MRTG

[Meng Keng Lee]

Hello,
To see what value it will produce I set the ThreshMaxO[A2RT01.Fa4_0_0.load]:0% and run a perl script to show the current parameter value.
 
But the value I get is 26052.2781666667 and 5179.73132222222. Both value are definitely not below 100%
 
Any help on this?

Try appending a % to the 70.

Ditto.

Line should look like this:

ThreshMaxO[A2RT01.Fa4_0_0.load]:70%

That should do it.
