JMX metric to report number failed WCL ALL

[onmstester onmstester]

I'm using RF=2 and Write consistency = ONE, is there a counter in cassandra jmx 
to report number of writes that only acknowledged by one node (instead of both 
replica's)?  Although i don't care all replicas acknowledge the write, but i 
consider this as normal status of cluster. Sent using Zoho Mail
