[mrtg] Re: Alteon 180E Total Sessions

[Koelstra, J. (Jan)]

Jon,

As long as you do not use the 'gauge' option MRTG calculates the rate
per second. You can specify 'perminute' or 'perhour' at the options line
to get the numbers higher.

As I understand the gauge option, it is used only when the counter is a 
meter and not incrementing. In this case, it's total number of sessions,

so if I'm reading it correctly, I don't want to specify gauge.
Basically, 
It's a counter32 value that constantly increments according to the
number 
of sessions that have been load-balanced since the stats have last been 
cleared. The 5-minute value should equal about 6000, but I'm getting 
results between 10 and 20, instead.

Is MRTG taking the 6000 and dividing it by 300 to get the number per 
second?

Hi Jon,

Are you looking to just see the raw number of packets tranversed 
graphed?  Or are you looking for a rate.

If you're looking for the raw number, put "growright,gauge" in the
options 

field.  That will prevent any math from being done.

Hope that helps,

Tony
