How can we monitor the ZKFailOverController? Is there any way to know the ZKFC service status except ambari?

[#1]

I need to check the status of ZKFailOverController(ZKFC) service whether it is running or not, is there any way to collect the ZKFC health/ monitoring metrics in java code easily?

Also does the dfs.ha.zkfc.port property is version specific? I had one observation that this property is visible automatically on HDP 3.1 but not on HDP 2.5 although it is HA enable.
