@Joe, thanks for starting this thread, I was just thinking along this line of making sure bird is running.

Apollon, I would love to give your plugin a try. 

To summarize, I'm deploying Bird on 120 machines (2 nic each) + 6 routers (total of 240 ptp links in a clos configuration) and participate in a single area OSPF. Anyone know whether bird have been being deploy/tested in this use case?

thanks,

We are monitoring the process with icinga & check_mk. Check_mk has a
notion of state, so we essentially persist ("inventorize") the admin
state of all protocols (up/down) and their status (Connected, Running
etc) and if anything changes we get an alert.

I could share the check_mk plugin that does all this, if anyone is
interested.

We also monitor the prefix count directly in the Linux kernel (via
/proc/net/fib_triestat and /proc/net/rt6_stats) and use it to score our
keepalived processes higher or lower and possibly trigger a failover of
the access interface IPs if one router seems to receive significantly
less prefixes than the other for some reason.

Cheers,
Apollon
