should be decoded. It can be a separate ticket.
Hi @rbalamohan,
I checked what happens when profiling a method with "$".
From a command line the profiling command works if you escape the dollar
sign by adding "\" before "$" :
`curl
"http://localhost:10002/prof?output=tree&duration=30&interval=1&method=java.util.concurrent.locks.AbstractQueuedSynchronizer\$ConditionObject.awaitNanos"`
Than it generates an output file with name like this:
`async-prof-pid-73790-java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject.awaitNanos-4.tree`
To open it in a linux shell the file also needs to be escaped.
[async-prof-pid-73790-java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject.awaitNanos-4.tree.html.txt](https://github.com/apache/hive/files/11191887/async-prof-pid-73790-java.util.concurrent.locks.AbstractQueuedSynchronizer.ConditionObject.awaitNanos-4.tree.html.txt)
The output inside the output file is fine. A sample output file is attached.

> With async-profiler "-e classame.method", it is possible to profile specific
> events. Currently profileServlet supports events like cpu, alloc, lock etc.
> It will be good to enhance to support method name profiling as well.
