How does the bash wrapper report task failures?

The generated wrapper captures the exit code of your command ($?). If the command exits with non-zero, it can ping Uptime Kuma with status=down and an error message, immediately triggering notification channels.

Push_Interval_Seconds = Cron_Interval_Seconds; Grace_Period = Interval * 0.2 + Execution_Budget

Was this calculation helpful?

Understanding Your Results

Calculates the expected run interval and grace period in seconds, generates the wrapper bash snippet with exit-code handling and execution time tracking, and produces Terraform IaC resource definitions.

Practical Guidance & Next Steps

Always add a grace period (e.g. 20% or 60-120 seconds) to push monitors so network jitter or minor execution duration variations do not trigger false positive downtime alerts.

What is this?

A DevOps automation utility that converts cron schedule expressions into Uptime Kuma push monitor configurations and heartbeat curl scripts.

How does it work?

1. Paste your cron schedule expression and Uptime Kuma push URL. 2. Configure execution budget and grace period. 3. Copy the hardened bash wrapper or Terraform provider code.

Why use it?

Prevents silent cron job failures by ensuring Uptime Kuma alerts you whenever a scheduled job fails or stops sending heartbeats.

Technical Scope & Calculation Limitations

Converts standard 5-token crontab expressions into push intervals and heartbeat wrappers.

Frequently Asked Questions

Instead of Uptime Kuma actively pinging your server, your cron script sends an HTTP GET/POST to Uptime Kuma upon completion. If Uptime Kuma does not receive a ping within the expected interval plus grace period, it marks the monitor down.
