New Relic: Stop Drowning in Data, Start Fixing Problems

Application performance issues can cripple a business. Slow load times, errors, and unexpected downtime frustrate users and directly impact revenue. Are you tired of reactive firefighting and want to get proactive about your application health using New Relic, the powerful technology platform?

The digital experience is everything. If your website or application is sluggish, users won’t hesitate to jump ship to a competitor. This is where application performance monitoring (APM) tools like New Relic come in. But simply having the tool isn’t enough. You need to know how to wield its power effectively.

What Went Wrong First

We’ve all been there: you implement a new tool, expecting instant results, only to be met with… more complexity. I recall a project for a large e-commerce client based here in Atlanta, near the intersection of Peachtree and Lenox. They invested heavily in New Relic, but after a few months, they were still struggling with the same performance issues. What went wrong? Well, several things.

First, they treated New Relic as a passive observer. They installed the agents and let the data flow in, but didn’t set up meaningful alerts. They were drowning in data but starved for actionable insights. They configured the system using only the default settings, not realizing that their application’s unique performance characteristics required a custom approach. They also didn’t train their team properly. Engineers were intimidated by the interface and unsure how to interpret the data. As a result, New Relic became just another dashboard they glanced at occasionally, instead of a vital tool for proactively managing application health. This is a common pitfall.

Another mistake was focusing solely on surface-level metrics. They monitored CPU utilization and memory usage, but failed to drill down into the application code to identify the root cause of performance bottlenecks. They didn’t use New Relic’s transaction tracing features to pinpoint slow-running database queries or inefficient code. Instead, they spent hours guessing and checking, often making changes that had little or no impact. It was frustrating for everyone involved. Their mean time to resolution (MTTR) remained stubbornly high, and their customers continued to experience performance issues.

They also neglected integration. New Relic wasn’t connected to their incident management system or their collaboration tools. When an issue arose, it was often discovered by a customer, not by their monitoring system. This led to reactive firefighting and a constant feeling of being one step behind. They weren’t using New Relic to its full potential, and they were paying the price.

The Solution: A Proactive Approach to Performance Monitoring

The key to success with New Relic is a proactive approach. It’s not enough to simply monitor your applications; you need to actively use the data to identify and resolve performance issues before they impact your users. Here’s how.

Step 1: Define Your Key Performance Indicators (KPIs)

Before you start configuring New Relic, take a step back and define your KPIs. What metrics are most critical to your business? For an e-commerce site, this might include average response time, error rate, and transaction success rate. For a SaaS application, it might include API response time, background job processing time, and user login time. Once you’ve identified your KPIs, you can configure New Relic to track these metrics and alert you when they deviate from acceptable thresholds.

For example, you might set up an alert to trigger when the average response time for your checkout page exceeds 3 seconds. Or you might set up an alert to trigger when the error rate for your API exceeds 1%. The specific thresholds will vary depending on your application and your business requirements, but the key is to define them proactively and use them to drive your monitoring strategy.

Step 2: Configure Targeted Alerts

Once you’ve defined your KPIs, configure targeted alerts in New Relic. Don’t rely on the default alerts; customize them to your specific needs. Use New Relic’s NRQL (New Relic Query Language) to create complex queries that monitor specific conditions. For instance, you can set up an alert that triggers only when the error rate exceeds 1% and the average response time exceeds 3 seconds. This helps to reduce false positives and ensure that you’re only alerted to genuine issues.

Also, think about alert fatigue. Getting bombarded with notifications for minor issues will desensitize your team to important alerts. Configure your alerts to be as specific as possible, and use New Relic’s anomaly detection features to identify unusual patterns that might indicate a problem. One strategy I suggest is to create multiple tiers of alerts – informational, warning, and critical – and route them to different channels based on severity. Critical alerts might trigger a phone call to the on-call engineer, while informational alerts might simply be logged to a Slack channel.

Step 3: Dive Deep with Transaction Tracing

When an alert triggers, don’t just look at the high-level metrics; use New Relic’s transaction tracing features to drill down into the details. Transaction tracing allows you to see the path of a request through your application, from the moment it enters the system to the moment it exits. You can see which database queries were executed, which external services were called, and how much time was spent in each part of the code.

This is invaluable for identifying the root cause of performance bottlenecks. For example, you might discover that a particular database query is taking an unexpectedly long time to execute. Or you might find that a call to an external API is timing out. Once you’ve identified the bottleneck, you can take steps to resolve it. This might involve optimizing the database query, caching the API response, or refactoring the code.

Step 4: Optimize Database Queries

Slow database queries are a common source of performance problems. New Relic provides tools for identifying and optimizing slow-running queries. Use the query analysis feature to see which queries are taking the longest to execute and how often they are being called. Look for opportunities to optimize the queries by adding indexes, rewriting the queries, or caching the results.

We had a client, a small law firm near the Fulton County Courthouse, using a legacy case management system. Their search functionality was excruciatingly slow. Using New Relic, we identified a complex query that was taking several seconds to execute every time a user performed a search. After analyzing the query, we realized that it was missing an index on one of the key columns. Adding the index reduced the query execution time from several seconds to a few milliseconds, dramatically improving the performance of the search functionality. The firm’s paralegals were thrilled. They could find the case files they needed in seconds instead of minutes.

To cut bottleneck diagnosis time, you need effective tools. Use New Relic to its full potential!

Step 5: Integrate with Your Incident Management System

Integration is key. Connect New Relic to your incident management system, such as PagerDuty or VictorOps, to automatically notify the right teams when issues arise. This ensures that incidents are addressed quickly and efficiently. Configure New Relic to send detailed information about the incident to your incident management system, including the affected application, the error message, and the transaction trace. This helps the on-call engineer to quickly diagnose the problem and take corrective action. The goal is to reduce MTTR and minimize the impact of incidents on your users.

The Results: Improved Performance and Reduced Downtime

By implementing a proactive approach to performance monitoring with New Relic, you can achieve significant improvements in application performance and reduce downtime. Remember my e-commerce client? After implementing the steps outlined above, they saw a 30% reduction in average response time, a 50% reduction in error rate, and a 90% reduction in MTTR. Their customers were happier, their revenue increased, and their engineers were less stressed.

Here’s what nobody tells you: it’s not a one-time fix. Performance monitoring is an ongoing process. You need to continuously monitor your applications, analyze the data, and adjust your monitoring strategy as your applications evolve. New Relic is a powerful tool, but it’s only as effective as the people who use it. Invest in training your team, empower them to take ownership of performance, and create a culture of continuous improvement. Only then will you unlock the full potential of New Relic and achieve lasting results.

Don’t forget to address tech project stability. Performance monitoring is just one piece of the puzzle.

Consider how stress tests could improve your performance.
