Can't you get the length of the list on the monitoring side of things ?

Hello,
we are trying to monitor our cassandra cluster with Nagios JMX checks. While there are JMX attributes which expose the list of reachable/unreachable hosts, it would be very helpful to have additional numeric attributes exposing the size of these lists. This could be used to set thresholds (in Nagios monitoring) i.e. at least 3 hosts must be reachable before Nagios issues a warning.
This is probably not hard to do and we are willing to implement/supply patches if someone could point us in the right direction on where to implement it.
Greetings,
roland
