Hi All, I'm new to this list: we're using MRTG to monitor traffic flowing through two switches in our IXP; we gather information about every interface on each switch and then we compute overall sum of traffic for every device, the problem is:
- switch 1 (Enterasys) supports 64 bits counters - switch 2 (Dell) only supports 32 bits counters we defined a target which is the sum of overall traffic flowing through switch 1 & 2, but we can see that data collected by this third target are wrong, in the sense that global traffic is not equal to the sum of switch 1 & 2, furthermore the graph seems to be irregular, with lots of spikes and heavy ripplei (se http://www.namex.it for details). We think this is due to some error in adding values coming from 32 bits counters with values coming from 64 bits counters. We also poll each device once a minute. Has anyone had similar problems ? Any help would be greatly appreciated.
