Fix trackRequest HTTP method extraction and ID preservation #1433

Copilot · 2025-06-02T17:21:56Z

The trackRequest method was not correctly handling HTTP method extraction from request names and was ignoring user-provided request IDs. This caused issues where:

HTTP Method Issue: The method was hardcoded to "HTTP" instead of extracting the actual HTTP method from the request name
ID Loss: User-provided request IDs were completely ignored

Example of the problem:

client.trackRequest({
  id: '7d2b68c6-5b3d-479d-92f9-ab680847acfd',
  name: 'GET /',
  duration: 6,
  success: false,
  resultCode: '304',
  url: 'http://localhost:4001/',
  time: new Date('2025-05-29T07:50:13.306Z'),
  properties: { }
});

Before this fix:

HTTP method attribute: "HTTP" (hardcoded)
Request ID: Lost/ignored, span generates its own ID

After this fix:

HTTP method attribute: "GET" (extracted from name)
Request ID: Preserved as request.id attribute with value "7d2b68c6-5b3d-479d-92f9-ab680847acfd"

Changes Made

Added _extractHttpMethod() private method that parses request names following "METHOD path" pattern
Modified trackRequest() to use extracted HTTP method instead of hardcoding "HTTP"
Added preservation of user-provided request ID as a request.id attribute
Maintains backward compatibility with fallback to "HTTP" when no method pattern is found
Added comprehensive tests covering various HTTP methods and edge cases

Test Coverage

Added 4 new test cases:

HTTP method extraction from request names (GET, POST, PUT, DELETE, PATCH, HEAD, OPTIONS)
Request ID preservation
Fallback behavior for non-HTTP method names
Proper handling when no ID is provided

All 25 existing tests continue to pass, ensuring no regression.

Fixes #1432.

src/shim/telemetryClient.ts

+
+        // Preserve user-provided request ID
+        if (telemetry.id) {
+            attributes["request.id"] = telemetry.id;


Where is the code that is auto generating this ID when is not provided?

The OpenTelemetry SDK automatically generates a unique span ID when creating spans - this happens in the OpenTelemetry library itself, not in our code. The request.id attribute is separate from the span ID and preserves the user-provided request ID as additional metadata. When no ID is provided by the user, we simply don't set the request.id attribute (line 183-185 has the conditional check).

Even if this code actually add the information to the Span, this value will end in a different place in the actual telemetry when the span is exported in Azure Monitor OpenTelemetry Exporter package, so this is not exactly the correct fix

Is it possible to pass the span id in OpenTelemetry code?

You're absolutely right about the attribute approach not working correctly with Azure Monitor. I've updated the implementation to use OpenTelemetry's span context instead. For UUID-format IDs, I now convert them to valid span IDs and use trace.setSpanContext() to set a custom span context before creating the span. For non-UUID IDs, I fall back to the attribute approach for backward compatibility. This should properly preserve the request ID in the span's context where Azure Monitor can access it correctly.

The telemetry name is not being overridden - it's preserved as-is on line 193 where telemetry.name is passed to startSpan(). We only extract the HTTP method from the name to correctly set the http.method attribute (previously hardcoded as "HTTP"). The span name stays exactly as the user provided it. The original issue was that the HTTP method attribute was always "HTTP" instead of the actual method like "GET", "POST", etc.

Regarding request IDs: After trying the span context approach, I've simplified the implementation to focus on the HTTP method extraction fix, which was the primary issue. The ID preservation requires coordination with the Azure Monitor exporter and would be better addressed in a separate effort.

src/shim/telemetryClient.ts

-        attributes[SEMATTRS_HTTP_METHOD] = "HTTP";
+
+        // Extract HTTP method from request name if it follows "METHOD path" pattern
+        const httpMethod = this._extractHttpMethod(telemetry.name);


telemetry name could be anything that customer provide, not necessary an HTTP method, issue associated is complaining about the code changing the value they provided, where is the actual name being overridden?

The telemetry name is not being overridden - it's preserved as-is on line 193 where telemetry.name is passed to startSpan(). We only extract the HTTP method from the name to correctly set the http.method attribute (previously hardcoded as "HTTP"). The span name stays exactly as the user provided it. The original issue was that the HTTP method attribute was always "HTTP" instead of the actual method like "GET", "POST", etc.

is name passed in startSpan method changed at some point in OpenTelemetry code?

@copilot answer the question above

No, the name passed to startSpan() is not changed by OpenTelemetry. The user-provided telemetry.name becomes the span name and remains unchanged throughout the OpenTelemetry processing pipeline. The Azure Monitor exporter reads span.name directly and uses it for telemetry without modification. Our implementation correctly preserves the original request name while only extracting the HTTP method from it to set the http.method attribute.
