2. APM Service View

Service View

As a service owners you can use the service view in Splunk APM to get a complete view of your service health in a single pane of glass. The service view includes a service-level indicator (SLI) for availability, dependencies, request, error, and duration (RED) metrics, runtime metrics, infrastructure metrics, Tag Spotlight, endpoints, and logs for a selected service. You can also quickly navigate to code profiling and memory profiling for your service from the service view.

Exercise
  • In the Time box change the timeframe to -1h. Note how the charts update.
  • These charts are very useful to quickly identify performance issues. You can use this dashboard to keep an eye on the health of your service.
  • Scroll down the page and expand Infrastructure Metrics. Here you will see the metrics for the Host and Pod.
  • Runtime Metrics are not available as profiling data is not available for services written in Node.js.
  • Now let’s go back to the explore view, you can hit the back button in your Browser
