Review comment:
@suneet-s Thank you very much for your reply!
Some implementation classes are registered by default and we don't need to register them manually, such as **CacheMonitor**, **JettyMonitor** and **ExecutorServiceMonitor**. But some are not registered by default and need to be configured ourselves, such as **QueryCountStatsMonitor** and **TaskCountStatsMonitor**.

I found a description for **QueryCountStatsMonitor**, but not for **TaskCountStatsMonitor**. The description of **TaskCountStatsMonitor** might have been missed, so I added.
In our scenario, kafka has a large number of indexing tasks and a large amount of data that needs to be consumed with low latency. Therefore, task monitoring is very important.
We deployed the druid cluster with ambari, so monitoring and alerting were implemented based on ambari-metric-collector.
