New Relic is another widely used application performance monitoring tool in the Java community. New Relic provides grouped views for application and network performance statistics. This helps in the quick diagnosis of domain level problems. It also provides features for drilling down into specific requests for viewing performance metrics by response time, data transfer size, and throughput.

New Relic supports applications developed in Java, Scala, Ruby, Python, PHP, .NET, and Node.js. New Relic offers four different approaches for backend monitoring:

• Application performance management: In application performance management, New Relic features high-level metrics with the ability to drill down to the code level to see how the application is performing. On the dashboard, New Relic displays a response time graph. New Relic uses the Apdex index score method to distill metrics into performance indicators. New Relic requires the user to manually set the threshold values. 
• Server monitoring: New Relic focuses on the hardware the application servers are running on. The measurements include CPU usage, memory utilization, disk I/O, and network I/O. New Relic provides brief details on the heap memory and garbage collection attributes.
• Database monitoring: In New Relic, the dashboard for the database is a part of the application performance management dashboard. It is possible to view database monitoring metrics through plugins.
• Insights and analytics: New Relic has a built-in, opt-in database, which stores statistics and enables querying the database.
