Cron Job Monitoring
Track every scheduled job. Get alerted the moment one fails or runs late. Works with any language or runtime that can make an HTTP request.
Two minutes to integrate
Add a single line to your crontab. That is all it takes. Works with any language or runtime that can make an HTTP request.
We check so you don't have to
Ionhour pings your endpoints from multiple regions around the world. A single slow region won't trigger a false alarm — only confirmed outages fire alerts. Multi-region checks to avoid false alarms. Latency tracking and SSL expiry warnings. Custom headers, status codes, and response matching.
Map your service dependencies
Model external services your app relies on — Stripe, Redis, Auth providers. When a dependency goes down, Ionhour automatically propagates a DEGRADED state to every service that depends on it. Dedicated health probes per dependency. Automatic DEGRADED propagation across the graph. Blast-radius visibility before incidents escalate.
Status State Machine
Checks follow a clear lifecycle: NEW → OK → LATE → DOWN. Always know the exact state of every job.
Signal History & Logs
Full audit trail of every ping received — timestamps, HTTP headers, latency, and payload data.
Instant Alerts
