## Health v2 (maintenance only)
Score: 88/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 97, release rhythm 69, longevity 100
- inputs: {"age_days": 3448, "days_push": 18, "days_rel": 45, "gap_med": 101, "n_releases_24m": 4}
- flags: none
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
Atop is an ASCII full-screen performance monitor for Linux that reports system-level activity (CPU, memory, swap, disks, network) and per-process/thread resource consumption, including finished processes. It supports daily logging for long-term analysis, cgroup views, and optional per-process network and GPU monitoring.

## Use cases
- monitor cpu memory disk and network utilization on linux
- find which processes consumed resources including ones that exited
- log system activity daily for long-term performance analysis
- view resource usage per cgroup and docker container
- monitor gpu activity per process on linux
- generate system activity reports from historical logs
- troubleshoot server performance issues over ssh

## When to choose
- you need deep per-process resource accounting on Linux including exited processes
- you want persistent logging of system and process activity for later analysis
- you need cgroup/container-level resource visibility
- you prefer a powerful terminal-based monitor over GUI dashboards

## When to avoid
- you need a web-based dashboard or multi-host aggregation
- you are monitoring non-Linux systems
- you only need simple real-time metrics without historical logging
