systemd timer monitoring
Monitor systemd timers and services
OnCalendar schedules drift, units fail silently. A ping in ExecStartPost catches both.
ExecStartPost=/usr/bin/curl -fsS https://pingark.com/ping/your-id
How it works
Create a check with the schedule and a grace period. Your job pings its unique URL on every run. Miss the deadline plus grace and PingArk alerts you.
Failure context included
Signal start, success, failure and exit codes. Attach logs to pings. See run durations trend over time.
Alerts that reach you
Email, Slack, Discord, Telegram, webhooks and PagerDuty. One alert per incident and a recovery notice, never a flood.
