Uptime Debug Data

When an uptime monitor goes down it's not always clear what started failing. DebugBear's uptime debug data provides a detailed snapshot into failed checks.

Where to find it​

While a monitor is down, a Failure Details box appears on the monitor page.

You can also expand an item under Recent Incidents to see what debug data was collected.

Uptime check debug data

What's collected​

The uptime debug data includes the following information:

  • Why the check failed
  • What the result of the intial and verification check were
  • What response headers the server provided
  • The response body if your uptime check is configured to look for a particular string in the response

When debug data is collected​

Debug data is kept when a monitor goes from passing to failing, not for every failed check.

A fresh snapshot is also collected every 12 hours for ongoing outages. When an uptime monitor is flaky up to 4 debug snapshots are collected per 4-hour window.
