# View status/logs
📊 cron list
📊 cron runs uptime-5m
Workflow (Auto on "UPTIME CHECK")
- Ping:
📊 session_status+openclaw gateway status(via exec). - Success: Update
uptime/streak.json(hours += 5/60). If >=168h → writeuptime/uptime.json. - Fail: Write
uptime/dead.json{ts, downtime_start: now}. - Dirs: Auto-mkdir
uptime/.
Streak Reset: On fail → streak=0.
