Crash Log Cluster Agent

A ranked list of root-cause clusters with fix status, reproduction steps and an owner for each top cluster

Crash Log Cluster Agent: what goes in, what the agent does and what you get

What it does

After a release, 6,000 crash logs arrive and the team cannot tell whether it is one bug or fifty. This agent reads the crash logs and clusters them by stack trace signature, build and platform. For each cluster it checks whether a newer build already contains a fix by comparing it with the commit history and later logs, ranks the clusters by user impact, and asks for a reproduction on the top ones, with the steps and device facts gathered from the logs. It watches new logs and moves them into existing clusters, or opens a new one when a pattern does not match. It rechecks a cluster after a fix ships to see if crashes stopped. The developer approves how fixes are assigned. Edge case: two traces differing only in memory addresses are merged into one cluster.

How it works

Follow the arrows from top to bottom. The orange dashed arrow is the loop: when a check fails, the agent goes back and tries again.

How it decides

It groups logs by normalized stack signature, ranks by affected users and trend, and marks a cluster fixed only when new builds show no matching crashes.

  • Merge traces that differ only by memory addresses or line numbers
  • Rank by users affected, then by crash rate trend
  • Mark a cluster fixed after 3 days with no crashes on a build that includes the fix
  • Request a reproduction for clusters affecting more than 1 percent of users

Make it yours

Every agent is a starting point. You choose these settings for your own situation.

  • Clustering rule for stack traces
  • Impact threshold for reproduction (default 1 percent)
  • Days without crashes to call a fix verified (default 3)
  • Issue tracker used
  • Report schedule

What keeps you in control

It always asks you first

  • Developer approves assignment of each cluster to an owner

Hard limits

  • Never close an issue or assign owners without approval
  • Never share logs that contain personal data outside the team

It stops when

  • Done: Top clusters have owners and fixed clusters are verified
  • Stop: Log volume is too low to judge, so the agent waits for more data

An example run

What happensFrom 6,200 logs the agent builds 41 clusters. The top one, a null reference in the audio loader, affects 3.2 percent of users on build 4.2.1 and 4.2.2. The commit history shows a fix merged in 4.2.3. After 4.2.3 ships and 3 days pass, logs show 12 crashes, so the agent reopens the cluster with the new trace. The developer approves assigning it.
