[monit] How to Achieve "if x restarts within y cycles then exec ..."

[Art Age Software]

I would like to be able to execute an arbitrary action after a
specified number of restart attempts have failed. It appears that the
only thing allowed in the "if x restarts within y cycles" clause is
the timeout command. Is that true?

In my case, what I am trying to achieve is a node failover (using
heartbeat) if mysql has crashed and cannot be restarted after several
attempts. Something like:

  if 5 restarts within 10 cycles then exec "/usr/lib/heartbeat/hb_standby"

What would be the best way to achieve this?

Thanks,

Sam
