Does anyone know why my graph looks like this?
Polling interval = 60 seconds
This problem just started and apparently only exists on this interface.
Database size = 2.1GB
Version = 8.5
# of interfaces monitored = 420 w/ 386 nodes.
Well in retrospect I realize I should have supplied you with all this information upfront, so as not to waste your time - my apologies. However, fortunately, a simple deletion and re-addition of the interface has resolved the issue.
I wouldn't begin to claim to know, but it looked like a summarization issue.
Thanks for the speedy response man.
