Kubernetes: Splunk APM traces disappear after enabling Secure Application

Splunk APM stops showing traces for the Java application after you activate Secure Application.

After you set splunkObservability.secureAppEnabled=true, Secure Application is activated but Splunk APM traces for the Java application disappear.

A custom instrumentation.spec.java.image value might override the Java instrumentation image that the Splunk OpenTelemetry Collector Helm chart configures for Secure Application.

  1. Remove the custom instrumentation.spec.java.image value from the OpenTelemetry Operator instrumentation resource.
  2. Let the Splunk OpenTelemetry Collector Helm chart manage the Java instrumentation image.
  3. Restart the Java application pods.
