NodeJS Zero-Config Workshop

A workshop using Zero Configuration Auto-Instrumentation for NodeJS.

30 minutes Author Robert Castley

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.

Prerequisites

Outbound SSH access to port 2222.
Outbound HTTP access to port 8083.
Familiarity with the bash shell and vi/vim editor.

Next, we will deploy the OpenTelemetry Demo.
