In the release notes for 10.2 we see:
HTTP Tracing and Correlation
You can monitor the performance of HTTP requests made by your Java applications, such as REST, using:
- Java URLConnection
- Apache HTTPClient
- Spring HTTPClient
With this feature, you can:
- View backend performance metrics for each URL path.
- View aggregated performance metrics across the different providers that are separated by protocol/host/port.
- View additional transaction trace details, such as the request parameters and HTTP status code.
- Interact with these components and display their dependencies.
Distributed transactions across multiple JVMs over HTTP are automatically correlated when you insert a Correlation Identifier in the HTTP request header.
We have installed a 10.2 WebSphere Agent that is supposedly using REST but we are not seeing anything in the tree that indicates that we are seeing the WS.
