Unlock New Relic: Stop Guessing, Start Knowing

New Relic is a powerful technology platform for monitoring and observability, but mastering it can feel like climbing Mount Everest. Are you ready to unlock its full potential and stop relying on guesswork to troubleshoot your applications?

Key Takeaways

  • Configure New Relic’s Browser monitoring to track front-end performance metrics, including page load times and JavaScript errors, by adding the JavaScript snippet to your application’s <head> section.
  • Set up key transactions in New Relic APM to monitor critical user flows, like checkout processes, and receive alerts when performance degrades beyond defined thresholds (e.g., response time exceeds 2 seconds).
  • Use New Relic’s Infrastructure monitoring to track CPU usage, memory consumption, and disk I/O on your servers, and correlate these metrics with application performance data to identify resource bottlenecks.

1. Installing the New Relic Agent

The first step is getting the New Relic agent installed on your servers. This agent collects the data that New Relic uses for monitoring. The process varies depending on your operating system and programming language. For example, if you’re using a Debian-based Linux distribution, you can add the New Relic package repository and install the agent using apt-get. Make sure you have your New Relic license key handy; you’ll need it during the installation process. You can find detailed instructions for your specific environment on the New Relic documentation.

Pro Tip: Always use the latest version of the agent to take advantage of the newest features and security updates. We had a client last year who was running an outdated agent, and they missed a critical security patch that led to a minor incident.

2. Configuring APM (Application Performance Monitoring)

Once the agent is installed, the real fun begins. APM is where you can monitor the performance of your applications. You can see things like response times, error rates, and transaction traces. To configure APM, go to the New Relic UI and select the application you want to monitor. From there, you can configure things like transaction naming rules and error tracking settings. For example, you can tell New Relic to group similar transactions together based on a URL pattern or HTTP method. Also, ensure you configure your application server to properly forward request headers so New Relic can trace transactions across different services.

Common Mistake: Neglecting to configure transaction naming rules. This can lead to a messy dashboard with hundreds of ungrouped transactions, making it difficult to identify performance bottlenecks.

3. Setting Up Key Transactions

Not all transactions are created equal. Some are more critical to your business than others. That’s why you should set up key transactions in New Relic. Key transactions allow you to monitor the performance of specific user flows, like the checkout process or user login. To set up a key transaction, navigate to the APM section for your application, find the transaction you want to monitor, and mark it as a key transaction. You can then set up alerts that trigger when the performance of that transaction degrades. For example, you might want to be alerted if the average response time of the checkout process exceeds 2 seconds.

Pro Tip: Don’t go overboard with key transactions. Focus on the 3-5 most critical user flows in your application. More than that, and you’ll be drowning in alerts.

4. Diving into Transaction Traces

When a transaction is slow, you need to figure out why. That’s where transaction traces come in. Transaction traces show you the exact sequence of events that occurred during a transaction, including database queries, external service calls, and code execution. To view a transaction trace, navigate to the APM section for your application, find the transaction you’re interested in, and click on the “Traces” tab. From there, you can see a detailed breakdown of the transaction’s performance. We once used transaction traces to identify a slow database query that was causing a major performance bottleneck in our e-commerce application.

Common Mistake: Ignoring slow database queries. These are often the root cause of performance problems. Use transaction traces to identify and optimize these queries.

5. Exploring Infrastructure Monitoring

Application performance doesn’t exist in a vacuum. It’s heavily influenced by the underlying infrastructure. That’s why infrastructure monitoring is so important. New Relic Infrastructure allows you to monitor the performance of your servers, including CPU usage, memory consumption, and disk I/O. To set up infrastructure monitoring, you need to install the New Relic Infrastructure agent on your servers. Once the agent is installed, you can view infrastructure metrics in the New Relic UI. It’s also possible to correlate infrastructure metrics with application performance data to identify resource bottlenecks. For example, you might notice that application performance degrades when CPU usage on a particular server exceeds 80%.

Pro Tip: Set up alerts for critical infrastructure metrics, like CPU usage and disk space. This will help you proactively identify and address potential problems before they impact application performance.

6. Leveraging Browser Monitoring

While APM and Infrastructure monitoring are critical, don’t forget about the front-end. Browser monitoring allows you to track the performance of your web applications in the user’s browser. This includes things like page load times, JavaScript errors, and AJAX request performance. To set up browser monitoring, you need to add a JavaScript snippet to your application’s <head> section. You can find the snippet in the New Relic UI, under the “Browser” section for your application. Once the snippet is added, New Relic will start collecting data about your users’ browsing experience. I had a client who was shocked to discover that their website was taking over 10 seconds to load for users in certain geographic regions. Browser monitoring helped them identify and fix the problem. We’ve seen similar issues with iOS apps suffering from performance bottlenecks.

Common Mistake: Forgetting to enable browser monitoring. This leaves you blind to front-end performance issues, which can have a significant impact on user experience.

7. Crafting Effective Dashboards

All this data is useless if you can’t visualize it effectively. That’s where dashboards come in. New Relic allows you to create custom dashboards that display the metrics that are most important to you. You can add charts, tables, and other widgets to your dashboards. You can also share your dashboards with other members of your team. To create a dashboard, go to the New Relic UI and click on the “Dashboards” link. From there, you can create a new dashboard and add widgets to it. Consider creating separate dashboards for different teams or applications.

Pro Tip: Use dashboards to track your key performance indicators (KPIs). This will help you quickly identify trends and anomalies.

8. Setting Up Alerts and Notifications

Monitoring is only useful if you’re alerted when something goes wrong. Alerts and notifications allow you to be notified when certain metrics exceed predefined thresholds. For example, you might want to be alerted if the error rate for an application exceeds 5% or if CPU usage on a server exceeds 90%. To set up alerts, go to the New Relic UI and click on the “Alerts” link. From there, you can create new alert policies and conditions. You can also configure the notification channels that you want to use, such as email, Slack, or PagerDuty. A PagerDuty integration is vital for 24/7 on-call support.

Common Mistake: Setting alert thresholds too low. This can lead to alert fatigue, where you’re constantly being bombarded with notifications. Start with conservative thresholds and adjust them as needed. I recommend starting with a 10% error rate threshold and a 90% CPU utilization threshold.

9. Case Study: Improving E-Commerce Performance

Let’s look at a concrete example. We worked with an e-commerce company in Atlanta, GA, whose website was experiencing slow load times during peak shopping hours. Using New Relic, we identified that a particular database query was taking an excessively long time to execute. This query was responsible for retrieving product information for the homepage. We optimized the query by adding an index to the database table. This reduced the query execution time from 5 seconds to 50 milliseconds. As a result, the average page load time for the homepage decreased from 8 seconds to 3 seconds, a 62% improvement. This led to a significant increase in conversion rates and revenue. The company also used New Relic Synthetics to monitor their website’s uptime from multiple locations around the world. Sound familiar? We also helped another client solve a similar problem and avoid a crisis with load testing.

10. Staying Updated with New Relic

New Relic is constantly evolving, with new features and updates being released regularly. It’s important to stay up-to-date with the latest changes so that you can take advantage of them. The best way to do this is to subscribe to the New Relic blog and follow New Relic on social media. You should also attend New Relic’s webinars and conferences. And, of course, read the official documentation. Here’s what nobody tells you: New Relic’s support is actually pretty good, so don’t be afraid to reach out if you’re stuck. You can also learn from others’ mistakes – avoid common tech stability mistakes by being proactive with monitoring.
