A little more on what we got working:

While I didn’t do this myself, I’ve asked the colleague who did to write up a detailed blog post at some time in the future.

In the mean time, I took a look at what was deployed on our monitoring system and the configs in Git.

The check_bgp Nagios plugin script has the following header:

#!/usr/bin/perl -w
# nagios: +epn
#
# check_bgp - nagios plugin

It was found here I believe: https://exchange.nagios.org/directory/Plugins/Network-Protocols/BGP-2D4/check_bgp/details

As I mentioned it uses SNMP (as opposed to other ways of getting data off routers). As we already had SNMP set up for other things and an existing Nagios alerting systems, this made it easy to use that.

The exchange.nagios.org site is a decent resource for various Nagios related stuff.
