Monitoring Uptime: Find Failures Before Customers Do

A green server process does not prove that a customer can complete a call. Monitor the path that matters: the public endpoint, a representative application action and the dependencies that action needs.

Use different checks for different failures

A simple health endpoint can confirm that the process responds. A deeper readiness check can confirm that required dependencies are reachable. A synthetic transaction can test a user journey from outside the network. Keep the check lightweight and avoid making it perform a costly or destructive action.

Set alerts around impact

Alert on sustained failures, elevated latency, queue growth or exhausted provider capacity. One failed probe may be a network blip; a short rolling window can reduce noise while still catching a real outage. Send each alert to a named owner with the affected service, start time, recent deploy and a runbook link.

Monitor recovery, not just detection

Record when the service recovered and whether queued work completed. A system can return HTTP 200 while old webhook events remain stuck. Track both the availability signal and the business process, such as calls started, calls completed and outcomes written to the CRM.

Review alerts after incidents. Remove checks nobody acts on, tune thresholds that page too often and add a test for the failure you missed. Keep monitoring credentials separate from production write access and document who can acknowledge or silence an alert.
