Extracting service insights from Splunk APM

Review the Splunk APM homepage

Now that you have your OTel Collector in place and our applications instrumented, you should have data populating in the out of the box visualizations in Splunk APM. Let's get a feel for these highly valuable components of the product.

The Splunk APM homepage provides a high density view at a service/workflow level with historical context. Out of the box, this page shows you Top Services by Error Rate, Top Services by Latency (P90) as well as the Top Business Workflows by Error Rate and then by Duration (P90). For more details, choose a viewing preference: Service Map, Tag Spotlight, or Trace Search.

Review the Service Map

The Service Map is a visual representation of your various services and their dependencies. Splunk APM automatically discovers your instrumented services and their interactions to present dynamic and real-time service maps of your application’s architecture. Use the service map to make more sense of your complex network of services and quickly identify where issues may be occurring, in a visual way.

Review Tag Spotlight

Use Tag Spotlight to analyze the performance of your services to discover trends that contribute to high latency or error rates with indexed span tags. You can break down every indexed span tag for a particular service to view metrics for it. When you select specific span tag values or a specific time range, you can view representative traces to learn more about an outlying incident.
