NodeJS Zero-Config Workshop

The goal is to walk through the basic steps to configure the following components of the Splunk Observability Cloud platform:

• Splunk Infrastructure Monitoring (IM)
• Splunk Zero Configuration Auto Instrumentation for NodeJS (APM)
  • AlwaysOn Profiling
• Splunk Log Observer (LO)

We will deploy the OpenTelemetry Astronomy Shop application in Kubernetes, which contains two NodeJS services (Frontend & Payment Service). Once the application and the OpenTelemetry Connector are up and running, we will start seeing metrics, traces and logs via the Zero Configuration Auto Instrumentation for NodeJS that will be used by the Splunk Observability Cloud platform to provide insights into the application.

Next, we will deploy the OpenTelemetry Demo.
