Hello,

I would like to know how to read the hot threads information for a particular node and track the operations that cause high CPU usage. Below is a sample:

```auto
{field1}{field2}{field3}{IP1}{IP2:port}{di}{rack_ud=1, rack_fd=1}
Hot threads at 2022-09-05T01:53:17.587Z, interval=500ms, busiestThreads=10000, ignoreIdleThreads=true:
  58.3% (291.4ms out of 500ms) cpu usage by thread 'elasticsearch[node_name][[orders][0]: Lucene Merge Thread #1253796]'
   4/10 snapshots sharing following 19 elements
     org.apache.lucene.store.BufferedIndexInput.readVInt(BufferedIndexInput.java:221)
	 <additional_text>

```

Thank you,

---
