smem2 is a command line utility for Linux that reports process and system memory usage with a focus on proportional set size (PSS), giving a more realistic picture of shared memory use than RSS alone.
It reads live data from procfs, can generate reports for processes, users, mappings, and the whole system, and also works as a Python library for scripted use.
This is free and open source software.
Key Features
- Reports memory usage for processes, users, mappings, and the whole system.
- Shows proportional set size, unique set size, resident set size, and swap figures.
- Supports filtering by process, mapping, user, or specific PID.
- Offers totals, percentages, human-readable units, and configurable columns.
- Exports output in raw text or JSON format.
- Can be run with uvx or pipx, installed with pip, or imported as a Python library.
- Includes Docker support for running the tool and its test suite.
