Complete reference of all data collected by radar.

Summary

  • Cross-Platform System: Collectors that work on both Linux and macOS
  • Linux-Specific System: Linux-only collectors (systemd, /proc, /sys, etc.)
  • macOS-Specific System: macOS-only collectors (sysctl, system_profiler, diskutil, etc.)
  • PostgreSQL Instance: Instance-level PostgreSQL collectors
  • Per-Database: Schema and object collectors (per database)
  • pg_statviz (optional): Time-series statistics collectors (per database)

Output: All data collected in a single ZIP file named radar-{hostname}-{timestamp}.zip
