Re: Statistics output limit at 5k objects

I know of the SNMP issues with older cDot and 7-mode versions, but I wonder if using snmp might be a better way here?  Especially if you’re doing your own processing to load the data into a dB.

I’m also wondering if there was a way to use more qtrees instead of volumes, but that too opens another can of worms.

And have you looked at oncommand with the performance tool?  I suspect it’s not working for you too, since I don’t find it all the useful or easy to drill down into at times.
