Synthetic
Synthetic Monitoring Playbook for Web and API Uptime
Design scripts, intervals, and alert paths for proactive uptime coverage.

Model the real flow
Script login, cart, and API token refresh paths instead of just pinging a URL.
Use multiple regions and networks to detect locality issues early.
Checks to prioritize
- Auth flows
- Payment gateway paths
- Background task callbacks
Tune intervals and retries
Set fast 30-second checks for critical paths and slower 2 minute for non critical jobs.
Retry within the same region before paging to reduce false positives.
Make failures actionable
Attach runbook URLs and component owners to every synthetic monitor.
Send alerts to Slack plus status page drafts so communications keep pace.
