Capturing HTTP request and response headers
You can configure the agent to capture predefined HTTP headers as span attributes, according to the semantic convention. Use the following properties to define which HTTP headers you want to capture:
System property:
otel.instrumentation.http.client.capture-request-headers
Environment variable:
OTEL_INSTRUMENTATION_HTTP_CLIENT_CAPTURE_REQUEST_HEADERSDescription: A comma-separated list of HTTP header names. HTTP client instrumentations will capture HTTP request header values for all configured header names.
System property:
otel.instrumentation.http.client.capture-response-headers
Environment variable:
OTEL_INSTRUMENTATION_HTTP_CLIENT_CAPTURE_RESPONSE_HEADERSDescription: A comma-separated list of HTTP header names. HTTP client instrumentations will capture HTTP response header values for all configured header names.
System property:
otel.instrumentation.http.server.capture-request-headers
Environment variable:
OTEL_INSTRUMENTATION_HTTP_SERVER_CAPTURE_REQUEST_HEADERSDescription: A comma-separated list of HTTP header names. HTTP server instrumentations will capture HTTP request header values for all configured header names.
System property:
otel.instrumentation.http.server.capture-response-headers
Environment variable:
OTEL_INSTRUMENTATION_HTTP_SERVER_CAPTURE_RESPONSE_HEADERSDescription: A comma-separated list of HTTP header names. HTTP server instrumentations will capture HTTP response header values for all configured header names.
These configuration options are supported by all HTTP client and server instrumentations.
Note: The property/environment variable names listed in the table are still experimental, and thus are subject to change.
Capturing servlet request parameters
You can configure the agent to capture predefined HTTP request parameters as span attributes for requests that are handled by the Servlet API. Use the following property to define which servlet request parameters you want to capture:
System property:
otel.instrumentation.servlet.experimental.capture-request-parameters
Environment variable:
OTEL_INSTRUMENTATION_SERVLET_EXPERIMENTAL_CAPTURE_REQUEST_PARAMETERSDescription: A comma-separated list of request parameter names.
Note: The property/environment variable names listed in the table are still experimental, and thus are subject to change.
Configuring known HTTP methods
Configures the instrumentation to recognize an alternative set of HTTP request
methods. All other methods will be treated as _OTHER.
System property:
otel.instrumentation.http.known-methods
Environment variable:
OTEL_INSTRUMENTATION_HTTP_KNOWN_METHODSDefault: CONNECT,DELETE,GET,HEAD,OPTIONS,PATCH,POST,PUT,TRACE
Description:
A comma-separated list of known HTTP methods.
Enabling experimental HTTP telemetry
You can configure the agent to capture additional experimental HTTP telemetry data.
System property:
otel.instrumentation.http.client.emit-experimental-telemetry
Environment variable:
OTEL_INSTRUMENTATION_HTTP_CLIENT_EMIT_EXPERIMENTAL_TELEMETRYDefault: false
Description:
Enables the experimental HTTP client telemetry.
System property:
otel.instrumentation.http.server.emit-experimental-telemetry
Environment variable:
OTEL_INSTRUMENTATION_HTTP_SERVER_EMIT_EXPERIMENTAL_TELEMETRYDefault: false
Description:
Enables the experimental HTTP server telemetry.
For client and server spans, the following attributes are added:
http.request.body.sizeandhttp.response.body.size: The size of the request and response bodies, respectively.
For client metrics, the following metrics are created:
For server metrics, the following metrics are created:
