Spring Actuator created extra resources in APM

So sánh hành vi tracing giữa các phiên bản 1.53.0 và 1.55.0 đối với các request của Spring Actuator, sử dụng entry point OperationHandler.handle và trace DD_TRACE_DEBUG được cung cấp làm bằng chứng ban đầu. Tái hiện request health-check của Kubernetes và xác minh rằng các actuator resource bị loại trừ không còn tạo thêm APM resource.

Bug Report

After updating from 1.40.1 to 1.55.0, I noticed a lot of requests for a Resource named OperationHandler.handle inside APM on a Service. I eventually linked it to Spring Actuator requests, mostly from a Kubernetes health check.
We have ".*/actuator.*" set to be excluded at the Datadog Agent level in the cluster, but there seemed to be a new span created for each actuator call.

I gradually reverted the library version and once I got to 1.53.0, the issue went away.

Here's a bit of an excerpt for a single Trace from the logs with DD_TRACE_DEBUG=true:
