Pawas Chhokra commented on SAMZA-1153:
--------------------------------------

Here is the updated list of metrics we have decided to add:
# Number of subscriptions to zookeeper
# Number of notifications received (includes barrier state)
# Number of reads
# Number of writes
# Number of session timeouts
# Number of zookeeper connection errors
# isLeader metric to determine if a particular processor is the leader
# Time taken to rebalance after a processor change happens
