Cannot unmarshal bgp description #109

Open mickelmayers opened 9 months ago

mickelmayers commented 9 months ago

Hi,

I'm keep getting below logs on my device. Has any one seen such? I'm running exporter with command: /usr/local/bin/frr_exporter --collector.bgp.peer-descriptions.plain-text --collector.bgp --collector.bgp.peer-types --no-collector.ospf --no-collector.bfd --web.listen-address=0.0.0.0:9342

I've tried with --no-collector.bgp.peer-descriptions.plain-text and all other combinations with --no-collector.bgp.peer-descriptions but nothing seems to help.

Issue and logs only appear when --collector.bgp.peer-types enabled.

That is because --collector.bgp.peer-types expects a JSON formatted peer description. Please see https://github.com/tynany/frr_exporter?tab=readme-ov-file#bgp-frr_bgp_peer_types_up for more details, specifically:

To implement this metric, a JSON formatted description must be configured on your BGP group.

The easiest way to get rid of the error is probably to omit --collector.bgp.peer-types.

Let me know how you go
