Hi all,
I've got a PoC running using nautobot (source of truth, scrape with SD),
prometheus and snmp-exporter. It's scaling very well, much better than we
anticipated and we're very eager to put the finishing touches on the PoC.
I want to set a bunch of interfaces to either "monitored" or not. Based on
that, I will generate a label. For example:
"__meta_nautobot_monitored_interfaces":
"Fa0,Fa1".
A full return from Nautobot might be something like:
[ { "targets": [ "ORDER12345678" ], "labels": { "__meta_nautobot_status":
"Active", "__meta_nautobot_model": "Device", "__meta_nautobot_name":
"ORDER12345678", "__meta_nautobot_id":
"c301aebf-e92d-4f72-8f2b-5768144c42f4", "__meta_nautobot_primary_ip":
"xxx", "__meta_nautobot_primary_ip4": "xxx",
"__meta_nautobot_monitored_interfaces": "Fa0,Fa1", "__meta_nautobot_role":
"CPE", "__meta_nautobot_role_slug": "cpe", "__meta_nautobot_device_type":
"ASR9006", "__meta_nautobot_device_type_slug": "asr9006",
"__meta_nautobot_site": "Place", "__meta_nautobot_site_slug": "place" } } ]
My question is two-fold:
- I'd like to drop all unrelated interfaces. I don't know how to do that
using relabeling with this comma separated string. I'm open to presenting
the data in a different way, since I made the prometheus service discovery
plugin myself (based on the netbox one), but I haven't thought of a better
way.
- I only want to alert on the monitored interfaces. I mean, if we fix the
above, this is a non-issue, but if that's not possible, I'd like to at
least only alert on the monitored interfaces.
This is going to be run on ~20.000 devices with all differing
configuration, models, vendor, etc. It needs to be very dynamic and all
sourced from Nautobot, as well as be refreshed when changes are made there.
Using snmp.yml and a generator to do so doesn't seem feasible unless I'd
create a new module for every possible configuration, and that doesn't seem
ideal.
If anyone has any suggestions on how to accomplish this, I'd very much
appreciate it.
