Patrick,

There have been a couple recent jiras on this - capturing a

count of the number of connections in "srvr" comes to mind.

Are you referring to adding another entry for "number_of_client_connections" to both JMX and srvr/mntr ?

Please can you point me to a JIRA, if one exists ?

Thanks, Neha

Please add both jmx and 4lw, I think this would be useful for operators. There have been a couple recent jiras on this - capturing a count of the number of connections in "srvr" comes to mind. This would be useful summary there as well (in addition to being in stat and mntr).

Well, the point is to monitor and alert on it. So maybe a JMX bean or one of the 4-letter commands would be reasonable.

Also, a related question is being able to monitor the number of disconnect operations on a client. This is generally indicative of a client going through large number of GC and hence disconnecting way too often from a zookeeper cluster. What is a good way of monitoring this ?
