How to Fix New Relic Synthetics Api

In this tutorial, you'll learn about How to Fix New Relic Synthetics Api. We cover key concepts, practical examples, and best practices.

The Problem

Your New Relic synthetics api configuration is not working. Data is missing from dashboards, alerts do not fire, or the agent does not report.

New Relic provides full-stack observability, but synthetics api issues cause gaps in your monitoring coverage. The DodaTech platform team uses New Relic for application performance monitoring. Here is the fix.

Error Symptoms

You see in New Relic:

synthetics-api: No data received
Error: 30a5cd5dac39 synthetics-api configuration error

Wrong Configuration

This is the problematic synthetics api setup:

// Wrong: missing synthetics-api configuration
require('newrelic');
// Agent initialized without custom configuration

Without explicit synthetics api configuration, the New Relic agent uses defaults that may not instrument your application correctly.

Agent log:

newrelic_agent.log:
  info: Agent v11.0.0 started
  warn: synthetics-api not configured - using defaults

Right Configuration

Here is the correct synthetics api setup:

// Correct: proper synthetics-api configuration
const nr = require('newrelic');

// Custom configuration example
nr.instrument('my-module', function(shim, myModule) {
  shim.recordQuery(myModule, 'query', function(opts) {
    shim.logger.info('Recording query for synthetics-api');
    return opts;
  });
});

// Custom attribute tracking
nr.addCustomAttribute('synthetics_api', 'enabled');

Expected output:

newrelic_agent.log:
  info: New Relic agent v11.0.0 connected to collector
  info: Custom synthetics-api instrumentation registered
  info: Application "newrelic-synthetics-api" reporting to New Relic

Prevention

• Set NEW_RELIC_LICENSE_KEY as an environment variable, never hardcode it
• Use the New Relic CLI tool (newrelic) for account and entity management
• Validate NRQL queries in the New Relic Query Builder before using in dashboards
• Enable distributed tracing for end-to-end transaction visibility across services
• Configure service-level indicators (SLIs) to track reliability metrics
• Review APM agent compatibility with your language and runtime versions
• Set up alert workflows with enrichment steps for contextual incident notifications

Common Mistakes with synthetics api

1. Overlapping type class instances that cause GHC to reject the program with ambiguous dispatch errors
2. Non-exhaustive pattern matches that compile with warnings then crash at runtime
3. Misunderstanding that String is [Char] with poor performance for large text operations

These mistakes appear frequently in real-world NEWRELIC code. DodaTech's contributors have identified these patterns through analysis of open-source projects and production systems.

Practice Exercise

Write a pure function that safely divides two integers using Maybe, then test it with edge cases like division by zero and negative numbers.

This exercise reinforces the concepts covered in this guide. Try implementing it before checking online solutions.
