Hi,
We have noticed an interesting problem where on all of our OpenBSD firewalls, every single interface on the same firewall reports the same discards rate.
We would like to try and work out which interface these discards are actually happening on, so we can work out what the cause is and check for a possible remedy (wrong VLANs being trunked through for example). If they are bad checksums, than that's ok. But would like to know ;)
Below is a screenshot showing the "Errors" graphs for all ports on the same server, notice how they are all displaying the same data.
My thoughts of how to start are; What is the SNMP OID being polled for this information?
I wonder if OpenBSD is incorrectly reporting the same value on all interfaces, or if there is only a single Discards counter/OID for the whole system, or if it is an Observium problem etc..
So if anyone can tell me the OID, I can do some more investigation first ;) I don't mind setting up OID mappings in SNMPD etc, if that is required I would be happy to provide a configuration template for Observium and OpenBSD. And I also wonder how up to date the OpenBSD MIB file built into Observium is?
Thanks in advance for your help :) Kind regards, Andy.
