Ping Clock
Ping Clock monitors cron jobs, backups, scheduled tasks and background workers through heartbeat pings. Unlike uptime monitors that check services responding to requests, it can detect when a scheduled job stops running. Each job pings a unique URL when it runs, and missed pings trigger alerts. Set a period and grace time or a cron expression in any time zone. Start, success and fail pings show whether a job never ran, failed or hung, and the job can send its exit code. Email and Slack alerts are available on every plan, with Microsoft Teams, Discord and webhooks on Starter and higher. Pro adds run-duration tracking, log capture and an API. The Free plan includes 20 checks with no credit card required.
