Maybe you want to use type 'derive' rather than 'counter' as possibly the MRTG counter-wrap-detection code is kicking in when you dont want it to (because you're calculating this yourself)?
Counters has not reached 2^32 so there is no chance of a counter wrap or issues related to it.
Also, run the script manually a few times to be sure its not really outputting zeros on every third execution...
I tried running it every 5 minutes myself. Here are a few debug output I gathered.

Finally, check your MaxBytes setting is correct. Possibly this is dropping things to zero.
Yea, I did think that it might have beent he reason so I set the AbsMax to quiet high..but still things are same. Regards, Gaurav
Steve ________________________________________ I am trying to use MRTG to graph bandwidth usage of each classids my linux bandwidth manager has. I am using tc for the bandwidth manager and a pass persist script to get those values off the tc command. The script is working well I can get the value off snmp from my graphing server as well. But what am I seeing is, after a certain count say 3 regular polls the graphs fall to 0 'zero' and rise again. To my knowledge the usage never dropped, the host was downloading uniformly. But MRTG dropped the data to 0 and rose again and again falls to 0.
