Host Polling Interleaving

#1 Post by UKS-Gavin » Mon Sep 07, 2009 11:10 am

Hi All,

We have an appliance that falls over if we query it for too many SNMP OID's at once.

At the moment this is causing us an issue with Cacti because we can't limit/restrict the amount of queries that this individual host see's at once per poller.

Does anyone know of a good way to limit the amount of OID's on a per-host basis? Or another way around this. I've looked at the Cacti settings and we can only seem to do this on the system as a whole.


Thanks
Gavin

Upgrade?

I had the same problem, but could change Maximum OID's Per Get Request on the affected device.

Just checked, this feature was added in 0.8.7.

That would help for sure. But you can deactivate walking completly. too.
Set this parameter to 1 or 0 to deactivate snmp-walking.

This advice is correct but applies to "latest" cacti only

Hi Gandalf,

I think you missed on this one. We're after the ability to specify on a per-host basis to delay the SNMP OID queries so that they could for example be spread out over our 60 second polling interval.

At the moment I'm looking at putting a wrapper script in place with an arbitrary delay instead..

I would of course appreciate something more graceful.. Any ideas?

Thanks
