Re: Guage RRD Behavior
Steve: Looks like a normalization issue. RRD picks the timestamps of the intervals for you using your supplied stepsize but uses its timestamps. This means that if samples are every 10 seconds and...

Steve: "You can cause the normalisation to be a null operator by ensuring that you update on every step boundary - not a second early or late - and do no consolidation. " "Don't expect values. Expect...

Nope. Normalization is the answer I was looking for. The solution is fudge the check 1->2 is always 1.6, 2->1 is always 1.3 so we just weigh the value against 1.5 instead of ==1 or ==2. The take...

I think in this case, (depending on other factors certainly), I might consider not using zenperfsnmp to gather the data - i.e. for a binary value with 2 or 3 possible states, and/or you don't need to...

Nillie: Yes, normalization. Steve: Maybe write a daemon that uses the twisted framework to perform the snmp tasks and update statuses/create events rather than storing the data.

And how do you know the interface status before you receive one of these traps ? On my networks I have interfaces with more than 400 days of uptime and I suspect I'll have to wait some more before I...
