How to get zxid of a zookeeper server?

Zookeeper assigns a unique number for each transaction called zxid. It has two parts - an epoch and a counter. I could find the epoch value in zookeeper's data directory. However I cant find the counter. Does anyone know where I can find it?

In general, how to get zxid for zookeeper?

Also looking at the current status of zookeeper server can show the zxid which is answered in another post. Firt i executed telnet:

telnet localhost 2181

Then send following data to server:

stats

and then received following information:

Zookeeper version: 3.4.13-2d71af4dbe22557fda74f9a9b4309b15a7487f03, built on 06/29/2018 00:39 GMT

Connection to host lost.

As you see the zxid is currently 0xd0 in my zookeeper server.
