Initialize APM

This code initializes the APM agent with the specified service name, server URL, and environment. Initialization is the first step to start monitoring your application.

const { init } = require('@elastic/apm-rum-core');
const apm = init({
  serviceName: 'my-service',
  serverUrl: 'http://localhost:8200',
  environment: 'production'
});

Capture Page Load Metrics

This function captures the page load metrics, including the time it takes for the page to load and other relevant performance data.

apm.capturePageLoad();

Capture Custom Transactions

This code demonstrates how to capture custom transactions. You can start a transaction, perform some operations, and then end the transaction to capture its performance metrics.

const transaction = apm.startTransaction('custom-transaction', 'custom');
// Perform some operations
transaction.end();

Capture Errors

This code captures errors that occur in your application. It helps you track and analyze errors to improve the stability and reliability of your application.

try {
  // Some code that might throw an error
} catch (error) {
  apm.captureError(error);
}
