I am able to connect to JMX with Jconsole, but I don't see ZK-specific
MBeans in there.
For example, when I'm trying to collects stats via JMX I get errors like:

javax.management.AttributeNotFoundException: No such attribute:
PendingRevalidationCount
javax.management.AttributeNotFoundException: No such attribute:
AvgRequestLatency
javax.management.AttributeNotFoundException: No such attribute:
MaxRequestLatency
javax.management.AttributeNotFoundException: No such attribute:
MinRequestLatency
javax.management.AttributeNotFoundException: No such attribute:
NumAliveConnections
javax.management.AttributeNotFoundException: No such attribute:
MaxClientCnxnsPerHost
javax.management.AttributeNotFoundException: No such attribute:
OutstandingRequests
javax.management.AttributeNotFoundException: No such attribute:
PacketsReceived
javax.management.AttributeNotFoundException: No such attribute: PacketsSent

And these MBeans just don't seem to be there at all.

I'm sending a JConsole screenshot and hope the ML will not remove it.  If
it removes it, I'll post it somewhere.

Any help would be greatly appreciated.

Thanks,
Otis
