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)? Also, run the script manually a few times to be sure its not really outputting zeros on every third execution... Finally, check your MaxBytes setting is correct. Possibly this is dropping things to zero.
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. _______________________________________________ mrtg mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/mrtg
