# server-spy

> A terminal tool that measures CPU, memory and I/O congestion on shared servers and shows how much each of your experiment runs was slowed down by it.

Key notes:

- runs as a small background daemon; the TUI attaches, detaches and reattaches at any time
- classifies your experiment processes with a simple name or regex filter and tracks each distinct parameter combination as a run
- records scheduler wait and PSI stall penalties per run, and identifies which other users and processes caused the congestion
- installs on any Linux (static binary, apt repo, cargo, nix); snapshots save to plain CSV
