Agentes APM

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,

  },
  transaction_tracer: {
    enabled: true,
    transaction_threshold: 'apdex_f',
    record_sql: 'obfuscated'
  }
};

# Install agent
npm install newrelic

# Run application
NEW_RELIC_LICENSE_KEY=xxx node -r newrelic app.js

Python

# newrelic.ini
[newrelic]
license_key = YOUR_LICENSE_KEY
app_name = My Application
distributed_tracing.enabled = true
transaction_tracer.enabled = true
error_collector.enabled = true
browser_monitoring.auto_instrument = true

# Install agent
pip install newrelic

# Generate config file
newrelic-admin generate-config YOUR_LICENSE_KEY newrelic.ini

# Run application
NEW_RELIC_CONFIG_FILE=newrelic.ini newrelic-admin run-program python app.py

# Or with gunicorn
NEW_RELIC_CONFIG_FILE=newrelic.ini newrelic-admin run-program gunicorn app:app

Java

# Download agent
curl -O https://download.newrelic.com/newrelic/java-agent/newrelic-agent/current/newrelic-java.zip
unzip newrelic-java.zip

# Configure newrelic.yml
# license_key: YOUR_LICENSE_KEY
# app_name: My Application

# Run with agent
java -javaagent:/path/to/newrelic.jar -jar myapp.jar

Go

package main

import (
    "github.com/newrelic/go-agent/v3/newrelic"
    "net/http"

Instrumentação Personalizada

Eventos Personalizados

import newrelic.agent

# Record custom event
newrelic.agent.record_custom_event('OrderPlaced', {
    'order_id': '12345',
    'amount': 99.99,
    'customer_id': 'cust_001'
})

Métricas Personalizadas

import newrelic.agent

# Registrar métrica personalizada
newrelic.agent.record_custom_metric('Custom/OrderValue', 99.99)

# Com atributos
newrelic.agent.record_custom_metric('Custom/ProcessingTime', 
    processing_time, 
    {'unit': 'milliseconds'}
)
