Root-Cause Analysis

What is a root-cause analysis?

Root-cause analysis is a method of problem solving, used to identify the root cause of an issue such as an outage.

Four Steps of Root-Cause Analysis

1. Identify the problem.
2. Establish timeline from the normal situation up to the time the problem occurred.
3. Distinguish between the root cause and other causal factors like using event correlation.
4. Create a causal graph between the root cause and the issue.
