Dear all
I am trying to graph the cumulative usage im megabytes of the ports from our
routers to our isps. So far my graphs are quite good except that the OIDs in
question that I am monitoring seem to wrap (go back to zero) after they get
to around 4000000000 bytes (2 ^ 32 bytes).
I was thinking that I could write a script to tweak the data that is stored
in the .log file to somehow recognise that the counter has wrapped and
simply process the .log data so that the data continues incrementing instead
of going back to zero.
I don't think this would be too hard to do with perl.
Does any one know the best way I should integrate this script with the mrtg
apllication software so that
(i) mrtg gathers the raw data from the router and updates the .log file (ii)
my script modifies the .log data so that the counter values keep
incrementing instead of wrapping back to zero and then (iii) rateup uses the
processed .log data to make the graph.
Appreciate anyones's response about this
thanks
Derek
