Log Lanes — multi-file log timeline correlator / ログレーン — 複数ファイル対応ログタイムライン相関器

Drop several log files from different services onto the page, and Log Lanes auto-detects timestamp formats, renders each file as its own lane on a shared zoomable timeline, and automatically flags silent gaps and message bursts. See cross-service incident sequences at a glance.

How to use

  1. Drag and drop multiple log files onto the page. Timestamp formats are auto-detected across common log types.
  2. Each file appears as its own labeled lane, sorted by timestamp across the entire timeline.
  3. Scroll and zoom the timeline to see temporal relationships between events across files.
  4. Spot red gap markers (silent periods) and blue burst markers (concentrated activity) to trace cause-and-effect across services.

All processing happens in your browser, so hundreds of megabytes of logs stay private. Ideal for troubleshooting distributed systems, microservices incidents, and correlating logs from multiple sources without external tools or context limits.
