Running the check on Ubuntu 22.04 and Bird 2.x - adding the --proto 6 flag when invoking the check script, it' errors out because there's no birdc6 binary anymore.

Output is not interpreted properly by Icinga2 / Nagios:

Hi

I'm playing with the check_bird_bgp check and I'm missing the output of performance data. I'd like to collect these over time, e.g. the number of accepted/exported, rejected and filtered routes per BGP session.

I see theses are already "read" in the code and used. But shown in the output only in case of WARNING or CRITICAL state (and not as machine readable data but before the status line). So the data is here - it would just be added to the output.

Any chance to get this added to the check script?

Cheers,
Mario

Asking to check for sessions of an unknown AS causes a silent error. This would IMHO better be handled with an UNKNOWN or even CRITICAL error as this indicates a misconfiguration of either BIRD or the check and shouldn't be silent.

$ check_bird_bgp --asn 64512 --ebgp
