JSTACK(1)

NAME
jstack - print Java stack traces of Java threads for a specified Java process

SYNOPSIS
Note: This command is experimental and unsupported.

jstack [options] pid

options
    This represents the jstack command-line options. See Options for the jstack Command.

pid The process ID for which the stack trace is printed. The process must be a Java process. To get a list of Java processes running on a machine, use either the ps command or, if the JVM processes are not running in a separate docker instance, the jps command.

DESCRIPTION
The jstack command prints Java stack traces of Java threads for a specified Java process. For each Java frame, the full class name, method name, byte code index (BCI), and line number, when available, are printed. C++ mangled names aren't demangled. To demangle C++ names, the output of this command can be piped to c++filt.

Note:

This command is unsupported and might not be available in future releases of the JDK. In Windows Systems where the dbgeng.dll file isn't present, the Debugging Tools for Windows must be installed so that these tools work. The PATH environment variable needs to contain the location of the jvm.dll that is used by the target process, or the location from which the core dump file was produced.

If the target JVM is started with an alternate temporary file location, jstack must use the same temporary file location for communication; this is true by default but see the -XX:AltTempDir option.

OPTIONS FOR THE JSTACK COMMAND

-l  The long listing option prints additional information about locks.

-h or -help
    Prints a help message.
