Cron job monitoring checklist for launch and review
Use this operational checklist before go-live, after deployment, and during periodic reviews. It validates that cron monitoring is configured correctly — it is not a step-by-step setup guide. For detailed setup, follow how to monitor cron jobs; for product context, see cron job monitoring.
Before setup
- ☐ Job owner is identified
- ☐ Schedule is documented
- ☐ Expected maximum runtime is known
- ☐ Success condition is defined
- ☐ Failure contact is assigned
Monitor configuration
- ☐ Heartbeat/check-in monitor type is selected
- ☐ Unique check-in URL is copied securely
- ☐ Expected interval matches the cron cadence
- ☐ Grace period covers healthy long runs
- ☐ Alert channels are connected
Job integration
- ☐ Check-in request runs only after successful completion
- ☐ Failure paths do not send a false-success check-in
- ☐ Network/HTTPS errors are handled so misses stay visible
- ☐ URL is stored in secrets or secure config
- ☐ Target deployment environment can reach the URL
Validation
- ☐ A successful run recorded a check-in
- ☐ A controlled missed-run test was performed
- ☐ DOWN incident was observed on a miss
- ☐ Recovery check-in closed the incident
- ☐ Email, Telegram or webhook delivery was verified as used
Ongoing operations
- ☐ Schedule changes are reflected in monitor interval
- ☐ Alert contacts remain active and owned
- ☐ Retired jobs have monitors removed
- ☐ Recent incidents were reviewed
- ☐ Backup, import and report jobs are re-audited periodically
How this checklist relates to setup
If any item fails, open the how-to guide for the configuration sequence, then return here to re-validate. The commercial cron landing explains why missed-run monitoring matters; the heartbeat page explains the check-in mechanism.
What this checklist does not replace
It does not install cron, read crontab, or prove job success without an inbound check-in. It also does not replace log analysis for root cause inside a failed script.
Ready to create the monitor
When every required box is confirmed for the jobs you care about, create or update the heartbeat monitors and keep this checklist in your runbook for the next schedule change.
Practical monitoring guide
Example content below is illustrative — values are placeholders, not live customer data.
Jobs to include in a review
- Nightly backups and data exports that must finish before business hours.
- Billing, invoicing or subscription renewal batch jobs.
- Search index rebuilds, cache warmers and ETL pipelines.
- Certificate renewal scripts and DNS sync tasks tied to uptime.
Validation checks for check-ins
- Confirm interval and grace match the documented schedule.
- Confirm check-ins occur only after successful completion.
- Confirm owner and alert contacts are still correct.
- Confirm a controlled miss opened DOWN and recovery closed it.
Example missed cron alert
Heartbeat missed: invoice-export did not ping within the 45-minute window
Common mistakes
- Monitoring only server uptime while scheduled jobs silently stop.
- Heartbeats sent before work finishes, masking partial failures.
- No owner when cron logs rotate away before anyone reads them.
Frequently asked questions
When should the checklist be used?
Before production launch, after deployment changes, and during periodic monitoring reviews.
What should be tested before production?
Confirm a successful check-in, a controlled miss that opens DOWN, recovery, and alert delivery on the channels you use.
How can false-success check-ins be avoided?
Place the check-in only on the success path after work finishes; do not ping at job start or from failure handlers.
How often should alert contacts be reviewed?
Whenever ownership or on-call changes, and at least during periodic ops reviews.
What should be checked after changing a cron schedule?
Update expected interval and grace, then re-run a controlled miss/recovery test.
Should recovery alerts be tested?
Yes. After a test miss, send a successful check-in and confirm recovery notification if your contacts expect it.
Which jobs should be included in a monitoring review?
Backups, imports, reports, billing batches and any schedule whose silence breaks downstream work.
Does the checklist replace the setup guide?
No. Use the how-to guide for the configuration sequence; use this checklist to validate and review.
