Mike's System Monitor (msysmon) v1.0.0 August 10, 2026

Mike’s System Monitor (msysmon) is a lightweight administrator/developer tool for monitoring the CPU, memory, and threads used by processes on a Linux or macOS system. I wrote it primarily to do long-term testing of embedded Linux systems where memory leaks, crashes, and/or CPU spins can cause problems but are often hard to track down.

msysmon runs in the background to collect usage information and provides a simple web interface for viewing it complete with graphs.

Enjoy!
