How to leverage New Relic in production environment ?

Use Case: Movie Recommendation

New Relic can be highly useful in a production environment such as a movie streaming and recommendation platform like Netflix in the following ways-

Monitoring recommendation engine performance: In a movie recommendation system, the performance of the recommendation model is crucial for providing accurate and relevant suggestions.

Example: New Relic’s Application Performance Monitoring (APM) and error logs functionalities can be used to monitor the performance of the recommendation engine, helping identify issues like slow response times, high error rates, or increased latency or exceptions.

Error Logs

In the above example I can see two errors as response to GET request in a movie recommendation task, one arising due to ‘occupation’ not found and one due to the request timing out.

Infrastructure monitoring: A movie recommendation platform will also require a robust infrastructure to handle large amounts of data along with many user requests.

Example: Under the Infrastructure feature, you can help track resource utilization, network performance, and other key metrics like CPU% usage, Load Average, and % free memory, that helps ensure a high-quality user experience. If a sudden surge in user traffic is causing server overloads or network latency, Infrastructure Monitoring can help identify the affected components and enable the team to address the issue before it impacts user experience.

Infrastructure Performance Dashboard

Monitoring user experience: Ensuring availability, and a smooth and responsive user experience is critical for retaining and engaging users on a movie streaming platform.

Example: New Relic’s Browser and Mobile Monitoring solutions can help monitor frontend performance, including page load times, user interactions, and potential issues that could affect user experience.If users are experiencing slow load times when browsing the movie catalog, Browser Monitoring can help identify the root cause, such as inefficient JavaScript code or heavy media files, allowing the team to optimize the frontend for faster performance.

Monitoring API performance: Movie streaming platforms often rely on APIs for data exchange between various services, such as content delivery, user authentication, and billing. New Relic’s APM can be used to monitor API performance, ensuring that these services are running efficiently and reliably.

Example: If the content delivery API is experiencing high error rates or slow response times, APM can help identify the issue, enabling the team to address it and maintain a seamless content streaming experience for users.

Log management and analysis: In a complex ML-powered system like a movie streaming platform, log data can provide valuable insights into the system’s health and performance. New Relic’s Log Management solution can help collect, analyze, and visualize log data from various sources, making it easier to identify and troubleshoot issues.

Example: If there’s an unexpected drop in the accuracy of movie recommendations, Log Management can help correlate log data from the recommendation engine, data pipelines, and infrastructure components to identify the root cause and guide the team in resolving the issue.

By using New Relic in a production ML system like a movie streaming and recommendation platforms, teams can gain comprehensive insights into the application and infrastructure performance, enabling them to proactively address issues and maintain a high-quality user experience.

Strengths of the tool:

  1. Comprehensive monitoring: New Relic provides end-to-end monitoring across the entire software stack, including applications, infrastructure, and user experience.
  2. Real-time insights: The platform delivers real-time performance monitoring and analytics, enabling teams to detect and troubleshoot issues as they occur, minimizing the impact on end-users.
  3. Broad language and framework support: New Relic supports a wide range of programming languages, frameworks, and platforms, making it compatible with diverse technology stacks and suitable for various types of applications and industries.
  4. Customizability: New Relic allows users to create custom metrics, dashboards, and alerts tailored to their specific needs, providing a personalized view of the system’s performance and helping teams focus on the most relevant indicators.
  5. Ease of integration: New Relic offers numerous integrations with popular cloud providers like AWS, GCP, Azure, and DevOps tools, and other services, making it easy to incorporate the platform into existing workflows and environments.
  6. Collaboration within cross functional teams: The platform provides a unified view of application and infrastructure performance, facilitating collaboration among cross-functional teams and enabling them to work together effectively in addressing issues and improving system performance.


  1. Cost: New Relic can be expensive, particularly for small businesses and startups with limited budgets. The pricing model can become costly as the number of monitored services, users, and data volume increases.
  2. Complexity: The platform offers a wide range of features and capabilities, which can make it challenging for some users to navigate and use effectively. It may require a learning curve for users who are new to application performance monitoring and observability.
  3. Limited support for certain technologies: While New Relic supports many languages, frameworks, and platforms, it may not provide full support for some specific technologies or use cases. Users working with less common technologies may face limitations in monitoring and observability.
  4. Overhead and performance impact: Although New Relic aims to minimize the performance overhead associated with monitoring, some users have reported performance impacts when using the platform. This can be a concern, especially in resource-constrained environments or when monitoring highly sensitive applications.

How to integrate New Relic in your current ML project?

  1. Create a New Relic account: Go to the New Relic sign-up page ( and create an account using your email address or a supported single sign-on (SSO) provider.

newrelic-admin generate-config YOUR_LICENSE_KEY newrelic.ini
  • Edit the newrelic.ini file if you want to customize any agent settings, such as logging or data collection.
  • Copy your newrelic.ini file to your VM

After installation, you’ll see the following in your terminal-

3. Integrate New Relic with your Flask application:

  • Open your Flask application’s main Python file (e.g.,
  • Import the newrelic.agent package at the beginning of the file:
  • Before the Flask application instance is created, initialize the New Relic agent by adding the following line, specifying the path to your newrelic.ini configuration file:
  • newrelic.agent.initialize(‘newrelic.ini’)
  • To monitor your Flask application, wrap your app instance with the newrelic.agent.wsgi_application() decorator:
app = newrelic.agent.wsgi_application()(app)

3. Integrate logs:

  • Use this command into your host to enable infrastructure and logs metrics.
curl -Ls | bash && sudo NEW_RELIC_API_KEY=NRAK-OFHUHP4SF5GF3F52KZ6UBKM5SR7 NEW_RELIC_ACCOUNT_ID=3882989 /usr/local/bin/newrelic install -n logs-integration
