Class TracingInterceptor

Description

Interceptor that adds OpenTelemetry span attributes for incoming HTTP requests. Captures URL, body, headers, method, params, query, and response data. Supports exclusion of certain URLs via config, as well as granular exclusion of concrete span aspects — globally (TracingInterceptor.excludedAttributes) or per-URL (TracingInterceptor.excludedByURL, string entries match by substring inclusion, RegExp entries by test).

Example

{
  "TracingInterceptor": {
    "excluded": ["/health"],
    "excludedAttributes": ["response.data"],
    "excludedByURL": [{ "url": "/files", "attributes": ["body", "response"] }]
  }
}
