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,
