helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm repo update
helm install nodeexporter prometheus-community/prometheus-node-exporter 

2. Comment out these lines in the configuration.

3. From root directory of this repository, run:

cd ~/otel-agent 
helm install otel-agent-release nr-k8s-otel-collector -n newrelic --create-namespace

Confirm installation

Watch pods spin up:

kubectl get pods -A --watch 

Check logs of opentelemetry pod that spins up:

kubectl logs <otel-pod-name>

Confirm data coming through in New Relic

You should see data reporting into New Relic within a couple of seconds to the InfrastructureEvent table, Metric table, and Log tables.

FROM Metric SELECT * 

FROM InfrastructureEvent SELECT * 

FROM Log SELECT * 

Development notes

Iterating on otel config:

1. Make changes to the opentelemetry configuration
