Infrastructure Agent

Linux Installation

# Add repository and install
curl -Ls https://download.newrelic.com/install/newrelic-cli/scripts/install.sh | bash

# Configure license key
sudo NEW_RELIC_API_KEY=<YOUR_API_KEY> NEW_RELIC_ACCOUNT_ID=<ACCOUNT_ID> /usr/local/bin/newrelic install

# Or manual configuration
echo "license_key: YOUR_LICENSE_KEY" | sudo tee -a /etc/newrelic-infra.yml
sudo systemctl start newrelic-infra

Docker

# docker-compose.yml
version: '3.8'

services:
  newrelic-infra:
    image: newrelic/infrastructure:latest
    cap_add:
      - SYS_PTRACE
    privileged: true
    pid: "host"
    network_mode: "host"
    environment:
      - NRIA_LICENSE_KEY=${NEW_RELIC_LICENSE_KEY}
      - NRIA_DISPLAY_NAME=docker-host
    volumes:
      - /:/host:ro
      - /var/run/docker.sock:/var/run/docker.sock

Kubernetes

# Using Helm
helm repo add newrelic https://helm-charts.newrelic.com

helm install newrelic-bundle newrelic/nri-bundle \
  --namespace newrelic \
  --create-namespace \
  --set global.licenseKey=${NEW_RELIC_LICENSE_KEY} \
  --set global.cluster=my-cluster \
  --set newrelic-infrastructure.privileged=true \
  --set ksm.enabled=true \
  --set kubeEvents.enabled=true \
  --set logging.enabled=true

APM Agents

Node.js

// At the very start of your application
require('newrelic');

// newrelic.js configuration
exports.config = {
  app_name: ['My Application'],
  license_key: process.env.NEW_RELIC_LICENSE_KEY,
  distributed_tracing: {
    enabled: true
  },
  logging: {
    level: 'info'
  },
  error_collector: {
    enabled: true,
    ignore_status_codes: [404]
  },
  transaction_tracer: {
    enabled: true,
    transaction_threshold: 'apdex_f',
    record_sql: 'obfuscated'
  }
};
