netstat + cron is your friend at this point in time On Dec 18, 2012, at 8:25 PM, "aaron morton" <aa...@thelastpickle.com<mailto:aa...@thelastpickle.com>> wrote:
AFAIK the count connections is not exposed.

I want to know how many client connections has each one of my cluster nodes (to check if my load balancing is spreading in a balanced way, to check if increase in the cluster load can be related to an increase in the number of connections, and things like that). I was thinking about going with netstat, counting ESTABLISHED connections to port 9160, but then I thought maybe there is some way in cassandra to get that information (maybe a counter of connections in the JMX?). I've tried installing MX4J and going over all MBeans, but I haven't found any with a promising name, they all seem unrelated to this information. And I can't find anything skimming the manual, so... Can you think a better way than "netstat" to get this information? Better yet, is there anything similar to "Show processlist" in mysql?
