Interactive Log Parser Explorer

See log parsing in action! Use the interactive explorer below to step through 6 stages of log parsing. Watch as raw log data from different sources is progressively detected, parsed, and enriched.

How to Use This Explorer​

  1. Navigate using arrow keys (← →) or click the numbered stage buttons
  2. Compare the Input (left) and Output (right) at each stage
  3. Observe how fields are extracted (green highlight) or transformed (red strikethrough)
  4. Inspect the YAML code showing exactly what processor was added
  5. Learn from the stage description explaining the technique and benefits
