Usage

Check the spark docs for complete documentation.

The profiler subcommand is used to control the spark profiler.

Requires the permission spark or spark.profiler.

If the profiler is already running in the background, run:

/spark profiler open to open the profiler viewer page without stopping the profiler.
/spark profiler stop to stop the profiler and view the results.
/spark profiler cancel to cancel the profiler stop it without uploading the results.

For basic operation, run:

/spark profiler start to start the profiler in the default operation mode.
/spark profiler stop to stop the profiler and view the results.
/spark profiler info to check the current status of the profiler.

There are some additional flags which can be used to customize the behaviour of the profiler. You can use:

/spark profiler start --timeout <seconds> to start the profiler and automatically stop it after x seconds.
/spark profiler start --thread * to start the profiler and track all threads.
/spark profiler start --alloc to start the profiler and profile memory allocations (memory pressure) instead of CPU usage.

spark has no config to edit.
