Collecting JVM thread dumps

This guide describes how to generate JVM thread dumps.

Step 1: Getting PID

Find out the PID of the Java process.

macOS/Linux

ps -el | grep java

Windows

Press Ctrl+Shift+Esc to open Task Manager and find the PID of the Java process.

Use jstack to print the thread dump to the command line:

jstack -l <pid>

You can save thread dumps for multiple processes into a single file. Redirect the jstack output using the output redirection:

jstack -l <pid> >> threaddumps.log
