After you've sent us your OpenTelemetry data and opened your service (entity) in the UI, you can click on Errors to see total errors, as well as charts showing error count and error rate.
For your data to appear in this page, make sure it has the following:
span.kind = serveror
otel.status_code = ERROR
- Facets by span name
