snmp_exporter to preform snmpwalk on several VRFs in ACI

[Rem Markov]

Hey there guys!

The problem is quite simple.
I want to perform one snmpwalk, that will pull all the BGP peers in ACI,
The problem is that when not specifying context_name in the generator.yml, it will simply pull the metrics of `overlay-1`.

Does anyone know a way to create a single snmpwalk to pull all the vrfs bgp metrics?
In addition, in snmp_exporter, it seems that the only way to define context_name is in the auth, meaning for each vrf I must create a auth, which sounds like a waste, is it possible to create something in the APIC/ACI that, when "walking" it will pull all the configured VRFs?

When trying to create SNMP Context on the VRF I want to scrape, it only pulled the metrics from the last configured VRF even if all the VRFs had the "same" SNMP Context on them.

May be you need to customize to pull and consolidate information out of the box, not that i am ware ACI 5  have seen this.

i am only aware custom based on context config.

Hey there!

Seeing the same behavior when doing snmpwalks against the OOB IPs of Leaves.

Without specifying the SNMP Context of a custom VRF, I am not able to fetch BGP Neighbors of said custom VRFs (of e.g. L3OUTs).

Unfortunately I don't have a solution for you, I am currently sticking with one snmpwalk per VRF, specifying the context...

Well this is the expected answer and it seems as it the only solution.

Thank you a lot!
