`journalctl -u {{unit}}`
- Show messages by a specific unit in last 15m:
`journalctl -u {{unit}} --since {{-15m}}`
- Filter messages within a time range (either timestamp or placeholders like "yesterday"):
`journalctl -u {{unit}} --since {{now|today|yesterday|tomorrow}} --until {{YYYY-MM-DD HH:MM:SS}}`
- Show all messages by a specific process:
`journalctl _PID={{pid}}`
