Command line tool usecases need some explanation

[vitvlkv]

Hi!
I'm trying to figure out how to use your command line tool yjp-controller-api-redist.jar
I'm interested in "... the command line tool may be useful in remote profiling when you only have console access to the remote machine and no UI is available." this cases.

This page https://www.yourkit.com/docs/java/help/ ... e_tool.jsp unfortunately has very little info about each available command that the tool supports.

What is the purpose of `start-cpu-tracing` command? I tried it this way:
> java -jar yjp-controller-api-redist.jar localhost 5005 start-cpu-tracing
CPU tracing started
... wait some time...
> java -jar yjp-controller-api-redist.jar localhost 5005 stop-cpu-profiling
CPU profiling stopped

Fine! Where are the results? I expected to find some file in ~/Snapshots, but there is no. Could you explain, what this command - `start-cpu-tracing` - could be useful for?

Thank you!

Hi,

Starting or stopping profiling does not automatically capture snapshots. Instead, snapshots should be captured explicitly. Please see the commands with "capture" in their name.

In your case, please issue the "capture-performance-snapshot" command right after you stopped CPU profiling.

Best regards,
Anton
