ps_mem: A Lightweight Tool for Accurate Memory Usage Reporting

Are you looking for a reliable way to measure the memory footprint of your programs on Linux? Look no further than ps_mem! This simple Python script provides an accurate view of a program's in-core memory usage.

What it Does

ps_mem goes beyond the basic memory information provided by tools like ps. It delves into the /proc filesystem to extract a more precise picture of memory consumption, including:

• Resident Set Size (RSS): The amount of physical memory a process actively uses.
• Shared Memory: Memory shared with other processes. This helps identify potential memory optimization opportunities.

Key Features

• Accuracy: ps_mem leverages the /proc/$pid/smaps file for more accurate memory reporting compared to traditional methods.
• Lightweight: Being a Python script, ps_mem is easy to install and use, with minimal resource overhead.
• Informative Output: ps_mem displays memory usage in human-readable units (KiB, MiB, etc.) for easy comprehension.
• Process Counting: It also reports the number of processes with a specific name, aiding in identifying resource-intensive applications.
