jhsdb: Print stack and locks information of a Java process.
$ jhsdb jstack --pid ${pid}
try on your machine
The command "jhsdb jstack --pid ${pid}" is used to obtain a stack trace of a running Java process with a specific process ID (pid).
Here's a breakdown of what each part of the command means:
- "jhsdb" is the command-line tool name. It stands for "Java HotSpot Debugger", and it is primarily used for debugging and profiling Java applications running on the HotSpot JVM (Java Virtual Machine).
- "jstack" is the specific command to obtain a Java stack trace. It prints the stack frames of each thread in the target Java process. A stack trace provides information about the sequence of method calls that lead to the current execution point, helping in identifying potential issues or performance bottlenecks.
- "--pid" is an option to specify the process ID of the Java process for which you want to obtain the stack trace. "${pid}" is a placeholder indicating that you need to replace it with the actual process ID.
So, when you run the command "jhsdb jstack --pid ${pid}" and replace "${pid}" with the process ID of the desired Java process, it will generate and print the stack traces of all the threads running within that Java process.

never run a command you are not sure if it is safe.
