[mrtg] Re: Problems with external script

[Koelstra, J. (Jan)]

Michael,

How much is the change between 2 polls? By default MRTG calculates the
rate per second. 
If the output of the script changes less then 300 in a 5 minute interval
MRTG will show 0 per second.

To avoid this you can use perminute or perhour at option line.

Hth,

Jan.

Hi,

that was a good point. If I am adding "gauge" to the options than MRTG
starts 
working correctly. The only problem is that my data are of not of type
gauge. 
I need the difference between the data. In the manuals I reed:

"In the absence of 'gauge' or 'absolute' options, MRTG treats variables
as a 
counters and calculates the difference between the current and the
previous 
value and divides that by the elapsed time between the last two readings
to 
get the value to be plotted."

Why does MRTG not work it in my setup? Any idea ? Please find the
mrtg.cfg 
listed below:
