What problem does it solve?

Diagnosing issues in systemd-enabled environments requires fast access to structured, unit-scoped logs. This Skill provides targeted queries to pinpoint failures, verify startup behavior, and compare current and previous boots without manual log digging.

Core Features & Use Cases

  • Filter by unit, boot, time window, priority, and message content to isolate relevant events.
  • Export logs in human-readable text or machine-readable JSON for automation and auditing.
  • Perform maintenance checks and housekeeping with disk usage, rotate, and vacuum operations to manage journal size and integrity.

Quick Start

Run journalctl -u my-app.service -b -1 -p err to inspect the last boot's errors.
