Instrument your Node.js application in Kubernetes

Follow the instructions on this page to instrument your Node.js application running in Kubernetes. Make sure you have already installed the Observe Agent.

Add the OpenTelemetry zero-code instrumentation for Node.js.

Run the following commands to add zero-code instrumentation for your Node.js application, meaning you don’t have to modify your application’s source code to collect telemetry:

npm install @opentelemetry/sdk-node \
@opentelemetry/api \
@opentelemetry/auto-instrumentations-node \
@opentelemetry/sdk-metrics \
@opentelemetry/sdk-trace-node

Set the following environment variables to configure the Node.js instrumentation. Replace the placeholders such as ${YOUR_SERVICE_NAME} with the actual information from your environment.

export OTEL_SERVICE_NAME=${YOUR_SERVICE_NAME}
export NODE_OPTIONS="--require @opentelemetry/auto-instrumentations-node/register"
export OTEL_RESOURCE_ATTRIBUTES=deployment.environment=${YOUR_APP_ENVIRONMENT}
export OTEL_EXPORTER_OTLP_ENDPOINT=http://${YOUR_OBSERVE_AGENT_ENDPOINT}:4318
export OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf

Run your instrumented app:

node app.js
