Log Observer

Up until this point, there have been no code changes, yet tracing, profiling and Database Query Performance data is being sent to Splunk Observability Cloud.

Next we will work with the Splunk Log Observer to the mix to obtain log data from the Spring PetClinic application.

The Splunk OpenTelemetry Collector automatically collects logs from the Spring PetClinic application and sends them to Splunk Observability Cloud using the OTLP exporter, annotating the log events with trace_id, span_id and trace flags.

The Splunk Log Observer is then used to view the logs and with the changes to the log format the platform can automatically correlate log information with services and traces.
