Statistics

The statistics view aggregates data across all captured incidents in the NDJSON file. Switch to it from the header navigation in the dashboard.

Total errors

The total count of error packages in the file. This includes all error types and all time periods.

Errors by type

A breakdown of error counts grouped by error constructor name. This tells you whether your failures are dominated by a single error class (e.g., TypeError from a data shape issue) or spread across multiple types.

Top errors

The five most frequently occurring error messages, with their count. Repeated identical messages usually point to a single root cause that is triggered across multiple requests.

Hourly distribution

A chart showing the number of errors captured per hour. Use this to identify spikes (a failed deploy, a dependency outage) or patterns (higher error rates during peak traffic windows).

The chart covers the full time range of errors in the file. If your file contains errors from the last week, you will see hourly buckets for that entire period.
