[mrtg] 95/5 traffic accouting

[Steve Shipway]

I believe the 95/5 method is '95th percentile of 5-min average'.  Since MRTG normally polls at 5-min intervals this is possible.
 
If you use MRTG/RRDTool with the routers2 frontend, then you get the 95th Percentile calculations automatically, just add the 'percentile = yes' option in the routers2.conf.  You may also want to run rrd archiving (see the routers2 documentation) to keep a record if your billing is calculated at a specific time point every month.
 
There are also a couple of other utilities which will calcualte the 95th Percentile directly from .log or .rrd files (see the MRTG website)

all big provider are billing with a 95/5 method.
Is there any way to implement this to mrtg graphs?
