Root Cause Analysis

Moonin Root Cause Analysis combines deployment history, runtime context and policy signals to shorten the path from symptom to likely cause.

Inputs used by RCA

Section titled “Inputs used by RCA”
  • revisions and image changes
  • cluster and namespace scope
  • recent incidents
  • node and workload context
  • CronJob execution history when automation jobs are involved

Useful operator questions

Section titled “Useful operator questions”
  • did the issue start after a rollout?
  • is a failed scheduled job contributing to the incident?
  • is the problem limited to one cluster or broader?
  • did a temporary scaling rule change capacity shortly before the incident?
Section titled “Recommended workflow”
  1. start from the active error or workload
  2. inspect the latest revision and recent CronJob activity
  3. review cluster and node context
  4. confirm whether a policy, silence or scaling action changed the response path
