Your understanding is correct. snapCount is a system property with default value is 100,000. You can also set it in the zookeeper configuration file (conf/zoo.cfg) by using the parameter "snapCount".
I don't understand exactly what you mean by adhoc snapshot. From my understanding, if you want to take a snapshot early/more frequently reduce the value of snapCount. Also, you can use SnapshotFormatter to get the data in snapshot in plain text and analyze it.

Thank you. Is there a way to take an adhoc snapshot for troubleshooting / analysis of any issues? Upon looking for snapCount, I came across "zookeeper.snapCount" a system property with default value of 100,000. Is my understanding correct?
