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.
