Subject Re: how do i have more connections than maxClientCnxns?
Date Thu, 06 Nov 2014 18:52:50 GMT
Tim, the netstat -a will list all connections that are established,
including the ssh session and those of any other services. You could
check for ESTABLISHED connections that use the Zookeeper port, e.g.,
2181 on the remote side:

% netstat -an | sed '/^.*:2181[ ][ ]*ESTABLISHED.*/!d' | wc -l

However, why not ask Zookeeper itself?

% echo mntr | nc localhost 2181
[...]
zk_num_alive_connections        138
[...]
%
