“gops” is a command-line interface (CLI) tool designed to provide insights into Go processes that are currently running on a system. It helps diagnose and analyze Go programs, making it easier to understand their behavior and performance.
The main purpose of “gops” is to list and provide information about Go processes running on a system. By running the “gops” command, you can obtain a list of all currently running Go processes along with their process IDs (PIDs). This is particularly useful when you need to identify and work with specific Go processes for troubleshooting or debugging purposes.
Additionally, “gops” offers several diagnostic commands that provide more detailed information about a Go process. These diagnostic commands allow you to perform various tasks, such as inspecting the Goroutine stack traces, analyzing memory utilization, monitoring CPU profiles, and debugging using interactive GDB sessions.
The “gops” tool is built to be lightweight and minimally invasive. It relies on the debug information generated by Go programs during compilation, so there is no need to modify or instrument the code of the target application. This means you can use “gops” with existing Go programs without any additional setup or configuration.
“gops” is an open-source project maintained by Google, and its repository on GitHub (https://github.com/google/gops) provides additional details on installation, usage, and advanced features. The repository also includes examples and documentation on how to leverage “gops” effectively for diagnosing and analyzing Go processes.
gops Command Examples
1. Print all go processes running locally:
2. Print more information about a process:
# gops [pid]
3. Display a process tree:
# gops tree
4. Print the current stack trace from a target program:
# gops stack [pid|addr]
5. Print the current runtime memory statistics:
# gops memstats [pid|addr]
