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.

If you are interested below is my upstart conf (bird.conf) I am running Ubuntu so I removed the bird init.d script and added this in /etc/init/ <SNIP> description "BIRD Router Daemon" start on runlevel [2345] stop on runlevel [!2345] # An Upstart script to manage the foo service respawn expect fork script . /etc/default/bird exec /usr/sbin/bird $DAEMON_ARGS end script post-start script sleep 5 echo "my-foo service started at `date +"%F %T.%N"`" | mail -s "My-foo Service Started" user@email.com chown root.nagios /var/run/bird.ctl end script </SNIP> This appears to work rather well. That said I am sure there is a much better way of doing it… :) Joe On 23/04/2013, at 12:42 PM, Bao Nguyen <ngqbao@gmail.com> wrote:

@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,

Thanks Andy,

I can see that would work well for all things v4, but what about v6?

Ah - you see the flaw in my plan! It's not a problem exclusive to BIRD. SNMP support for BGP v6 sucks big time. Doesn't work on Quagga either.

Bird-snmp author here; While v4 has been standardized in BGP4-MIB, v6 is dependent on vendor-specific MIBS. Since bird-snmp is already a hack, I didn't want to clutter the code with vendor-specific hacks.

Thanks for the code - it's useful even without the v6 stuff.
