This is a usual case with big switch chassis.
There is another solution is to just filter out a few ports, you can for example graph only uplink-ports or similar.
And then you can make observium ignore the whole ifxEntry-table and only poll certain ports by activating the separate_walk-function on the device.

Would that maybe work for you?

Hey list,

how much work would it be to have an option to adjust the rrd step size
per device? Background is that we have a HP/H3C chassis that even with
latest firmware takes average 1000s to poll; with fdb already disabled.
98% of the time is spent in the ports module, polling ifEntry and
ifxEntry. We'd really like to at least get an hourly graph of the
traffic which is better then nothing. The idea is to put this dev into
its own group and have a different cron job for it (excluding this
group from the default one).

We do have a case with HP that is open for 2 years so the 'tell the
vendor that their SNMP engine is crap'-part was already done...

Steffen
