New Relic is a powerful technology platform, but its complexity can lead to missteps. Are you sure you’re getting the most out of your investment, or are you inadvertently sabotaging your monitoring efforts?
Key Takeaways
- Avoid over-reporting custom events by ensuring they are truly unique and valuable, not just noisy data.
- Properly configure alerting conditions in New Relic to reduce alert fatigue and ensure you are notified only of critical issues.
- Use New Relic’s tagging and filtering features diligently to organize data and make troubleshooting more efficient.
1. Ignoring the Basics: Installation and Configuration
This might seem obvious, but a surprising number of issues stem from improper initial setup. Did you really RTFM? Getting the agent installed correctly, with the right configuration settings, is paramount. For example, if you’re using the Java agent, ensure you’ve correctly configured the newrelic.yml file. Double-check the appname, license_key, and log_level settings. An incorrect appname can lead to data being reported to the wrong application in your New Relic account. A missing or incorrect license_key will prevent data from being reported altogether. And a verbose log_level in production can create unnecessary overhead.
Pro Tip: Always use environment variables for sensitive information like your license_key. This prevents accidentally committing it to your codebase.
2. Over-Reporting Custom Events
New Relic allows you to track custom events, which can be incredibly useful for gaining insights into specific application behavior. However, it’s easy to go overboard. I saw a startup in Midtown Atlanta last year that was tracking every single mouse click on their website as a custom event. The result? Their New Relic bill skyrocketed, and the sheer volume of data made it impossible to identify genuine problems.
Before creating a custom event, ask yourself: Is this data truly valuable? Will it help me identify performance bottlenecks, understand user behavior, or diagnose errors? If the answer is no, don’t track it. Focus on high-value events that provide meaningful insights. Think about tracking key business transactions, critical user interactions, or specific error conditions. Use the New Relic Insights dashboard to visualize your custom events and identify any that are generating excessive noise.
Common Mistake: Tracking personally identifiable information (PII) as custom events. This violates privacy regulations and can expose you to legal risk. Never store sensitive data in New Relic. Period.
3. Alerting Overload
Alerts are vital for proactive monitoring, but too many alerts can lead to alert fatigue. When every minor issue triggers a notification, your team will start ignoring them, and you’ll miss critical problems. A PagerDuty report from 2025 found that alert fatigue costs companies an average of $400,000 per year in lost productivity.
Configure your alerting conditions carefully. Use thresholds that are appropriate for your application and environment. Avoid setting alerts for purely informational metrics. Focus on metrics that directly impact user experience or business performance. For example, instead of alerting on CPU usage that spikes occasionally, alert on sustained high CPU usage that correlates with increased response times or error rates. Consider using dynamic baselines to automatically adjust alert thresholds based on historical data. Use New Relic’s anomaly detection features to identify unexpected behavior that warrants investigation. Also, leverage alert policies to group related alerts and reduce noise.
Pro Tip: Implement a feedback loop for alerts. When an alert triggers, document the cause and resolution. Use this information to refine your alerting conditions and prevent future false positives.
4. Neglecting Tagging and Filtering
As your application grows, your New Relic data will become more complex. Without proper organization, it can be difficult to find the information you need to troubleshoot problems. Tagging and filtering are essential for organizing your data and making it easier to analyze. Use tags to categorize your applications, hosts, and transactions based on environment (e.g., production, staging), team (e.g., frontend, backend), or function (e.g., API, web UI). Then, use filters to narrow down your data based on these tags. For example, you can filter your data to show only transactions from the production environment that are handled by the backend team.
I worked with a client in the Buckhead area of Atlanta who had a complex microservices architecture. They weren’t using tags at all. When something went wrong, it took them hours to figure out which service was responsible. After implementing a comprehensive tagging strategy, they were able to reduce their troubleshooting time by 50%. They tagged each service with its name, team, environment, and deployment version. They also used custom attributes to track request IDs and user IDs.
Common Mistake: Using inconsistent tagging conventions. Establish clear guidelines for tagging and ensure that everyone on your team follows them.
5. Ignoring the Query Builder
New Relic’s NRQL Query Builder is a powerful tool for exploring your data and creating custom dashboards. However, many users stick to the pre-built dashboards and never take advantage of the Query Builder’s capabilities. Don’t be one of them!
The Query Builder allows you to create highly customized queries that can provide insights into specific aspects of your application’s performance. You can use it to aggregate data, calculate metrics, and identify trends. For example, you can use the Query Builder to calculate the average response time for a specific transaction over a given time period, or to identify the most common error messages in your application logs. Learn NRQL – it’s worth it.
Pro Tip: Use the Query Builder to create custom dashboards that track the metrics that are most important to your business. Share these dashboards with your team to keep everyone informed about the health of your application.
6. Not Using Workloads
New Relic Workloads allows you to group related entities (applications, hosts, services) into logical units that represent specific business functions or teams. This makes it easier to monitor the overall health and performance of these units, and to identify dependencies between them. For example, you can create a Workload for your e-commerce platform that includes your website, payment gateway, and inventory management system. This will allow you to see at a glance whether the entire platform is functioning correctly.
I had a client last year who was struggling to manage their complex infrastructure. They had dozens of applications and services, and it was difficult to understand how they all fit together. After implementing Workloads, they were able to gain a much clearer picture of their infrastructure and identify bottlenecks that they had previously missed. Here’s what nobody tells you: Workloads are only as good as the thought you put into defining them. Don’t just throw things together; map them to real business units.
7. Forgetting About Log Management
New Relic Log Management is an often overlooked feature that can be incredibly valuable for troubleshooting and debugging. It allows you to collect, store, and analyze logs from your applications and infrastructure in a centralized location. This makes it easier to identify the root cause of problems, even when they span multiple systems.
Configure your log management settings to collect the logs that are most relevant to your application. Use filters to exclude noisy logs and focus on the ones that contain valuable information. Use the search and analysis tools to identify patterns and trends in your logs. For example, you can search for specific error messages or track the frequency of certain events. A recent report by the Georgia Tech Research Institute indicated that companies that effectively utilize log management reduce their mean time to resolution (MTTR) by up to 30%.
8. Ignoring the Mobile Monitoring
If you have a mobile app, you absolutely need to be using New Relic Mobile. It provides valuable insights into the performance and stability of your app, including crash rates, network performance, and user experience. Use New Relic Mobile to identify and fix performance bottlenecks in your app. Track user interactions and identify areas where users are experiencing friction. Monitor crash rates and identify the root cause of crashes. I’ve seen companies dramatically improve their app store ratings by addressing issues identified through New Relic Mobile.
Common Mistake: Only monitoring the backend and ignoring the mobile app. The mobile app is the front door to your business. Don’t neglect it.
9. Not Staying Up-to-Date
New Relic is constantly evolving, with new features and updates being released regularly. It’s important to stay up-to-date with these changes so that you can take advantage of the latest improvements and avoid potential problems. Subscribe to the New Relic blog, follow them on social media, and attend their webinars and conferences. Read the release notes carefully when upgrading your agents and plugins. Don’t just blindly upgrade without understanding the changes.
10. Neglecting Synthetic Monitoring
Synthetic monitoring allows you to proactively monitor the availability and performance of your applications by simulating user interactions. This can help you identify problems before they impact real users. Use synthetic monitors to test critical workflows, such as login, search, and checkout. Monitor the response times of your APIs and web pages. Set up alerts to notify you when a synthetic monitor fails. Synthetic monitoring is especially important for applications that are critical to your business or that have a large user base.
We had a client who ran a popular e-commerce site. They weren’t using synthetic monitoring, and they didn’t realize that their checkout process was failing intermittently. As a result, they were losing sales. After implementing synthetic monitoring, they were able to identify and fix the problem, and their sales increased significantly.
By avoiding these common mistakes, you can ensure that you’re getting the most out of your New Relic investment and that your applications are performing optimally. It’s about more than just installing the agent; it’s about actively using the platform’s features and continuously improving your monitoring practices.
