New Relic Mistakes Costing Tech Companies Big $$

For many companies, especially those in the technology sector, application performance is everything. A slow website, a buggy app, or unreliable API can drive customers away faster than you can say “404 error.” That’s why so many firms turn to New Relic, a powerful observability platform. But simply installing New Relic isn’t enough; you need to configure it correctly and avoid common pitfalls to truly reap its benefits. Are you making these costly mistakes?

I remember working with a fintech startup here in Atlanta called “SecureTrade.” They were processing a high volume of transactions daily and needed to ensure their platform was always available and performing optimally. They implemented New Relic, but a few months later, they were still struggling with frequent performance hiccups. Their CEO was frustrated, the development team was stressed, and customers were starting to complain.

The Case of the Confused Transactions

SecureTrade’s initial setup of New Relic was…basic. They had installed the agents, and data was flowing in, but it was all a jumbled mess. Transactions weren’t properly tagged, custom attributes were missing, and the default dashboards were overwhelming. When an issue arose, it took hours to sift through the noise and pinpoint the root cause.

For example, one Tuesday morning, their transaction processing time spiked dramatically. Users were reporting delays, and the support team was flooded with calls. The engineers scrambled, staring at graphs and logs, but couldn’t immediately identify the culprit. Was it the database? The API gateway? A specific microservice? Nobody knew for sure.

Mistake #1: Poor Data Organization

This is a classic New Relic mistake: failing to properly organize your data. Without clear tagging and custom attributes, you’re essentially flying blind. Tagging transactions with relevant information (e.g., transaction type, user ID, geographical region) allows you to slice and dice your data and quickly identify patterns.

Custom attributes are equally important. They allow you to add context to your data that’s specific to your application. For SecureTrade, this could include attributes like “payment method,” “transaction amount,” or “merchant ID.”

As Amazon Web Services suggests, a strong tagging strategy is essential for cost allocation, automation, and operational efficiency. The same principles apply to New Relic.

What happened with SecureTrade that Tuesday? After a painstaking investigation, they discovered that the spike in transaction time was caused by a faulty integration with a new payment processor. Because they hadn’t tagged transactions by payment method, it took them far too long to isolate the problem.

Mistake #2: Ignoring Alerts

Another critical mistake SecureTrade made was neglecting New Relic’s alerting features. New Relic allows you to set up alerts based on various metrics, such as response time, error rate, and CPU usage. When a metric crosses a predefined threshold, New Relic can notify you via email, Slack, PagerDuty, or other channels.

SecureTrade had a few basic alerts configured, but they weren’t comprehensive enough. They were missing alerts for critical services, and the thresholds were set too high. As a result, they often didn’t know about problems until users started complaining.

According to Atlassian, effective alerting is a cornerstone of incident management. You need to know about problems as soon as they occur, not hours later. A well-configured alerting system can give you a head start in resolving issues before they impact users.

We had a client last year who ran an e-commerce site. They didn’t set up alerts for slow database queries. One day, a poorly optimized query started bogging down their entire site during peak hours. Sales plummeted, and they lost thousands of dollars before they even realized what was happening. Don’t let that be you.

Mistake #3: Lack of Custom Dashboards

New Relic provides a wealth of data, but it can be overwhelming to sift through it all. That’s where custom dashboards come in. Custom dashboards allow you to visualize the metrics that are most important to your team. You can create dashboards for specific services, applications, or even individual team members.

SecureTrade relied primarily on New Relic’s default dashboards, which weren’t tailored to their specific needs. They had to manually navigate through different sections of the New Relic interface to find the information they needed. This was time-consuming and inefficient.

I’ve seen many teams create “war room” dashboards that display critical KPIs in real-time. These dashboards are often displayed on large screens in the office, providing a shared view of system health. This fosters collaboration and helps teams quickly identify and respond to issues.

Here’s what nobody tells you: building effective dashboards takes time and effort. You need to understand which metrics are most important to your business and how they relate to each other. Don’t be afraid to experiment and iterate on your dashboards until you find what works best for you.

The Turnaround

After a few weeks of frustration, SecureTrade brought in a consultant (that’s where I came in) to help them get their New Relic setup under control. We started by revamping their data organization strategy. We worked with their developers to identify key transaction types and custom attributes. We then implemented a consistent tagging scheme across their entire application stack.

Next, we configured a comprehensive set of alerts. We set up alerts for critical services, database queries, and API endpoints. We also adjusted the thresholds to ensure that alerts were triggered promptly but not too frequently (alert fatigue is a real problem!).

Finally, we created custom dashboards tailored to the needs of different teams. The operations team got a dashboard focused on system health and performance. The development team got a dashboard focused on code-level metrics. And the business team got a dashboard focused on key business KPIs, like transaction volume and revenue.

The results were dramatic. Within a few weeks, SecureTrade’s incident response time decreased by 50%. They were able to identify and resolve issues much faster, leading to improved application performance and increased customer satisfaction. The support team saw a significant drop in complaints, and the CEO finally started smiling again.

Here’s a specific example: after implementing the new alerting system, they caught a memory leak in one of their microservices before it caused a major outage. The alert triggered at 3:00 AM, and the on-call engineer was able to fix the problem within an hour. Without the alert, the leak would have continued to grow, eventually crashing the service and impacting thousands of users.

The Lesson Learned

SecureTrade’s experience highlights the importance of proper New Relic configuration. Simply installing the agents and hoping for the best is not enough. You need to take the time to organize your data, configure alerts, and create custom dashboards. Without these steps, you’re missing out on the full potential of New Relic.

One of the most effective things they did? They scheduled a monthly “New Relic Review” meeting where the team would analyze the data, identify areas for improvement, and adjust their configuration accordingly. This helped them stay proactive and prevent future problems.

New Relic is a powerful tool, but it’s only as good as the people using it. Don’t let these common mistakes hold you back. Invest the time and effort to configure New Relic properly, and you’ll reap the rewards of improved application performance, reduced downtime, and happier customers.

Don’t just collect data; understand it. Take the time to organize your New Relic data with meaningful tags and custom attributes. This simple step will transform your observability from a data dump into a powerful tool for diagnosing and resolving performance issues, saving you countless hours and potential revenue loss.
