Node.js profiling tools & monitoring solutions
Optimize the user experience of any Node.js application with end-to-end visibility that allows you to drill down into process call graphs, identify and diagnose memory leaks or performance bottlenecks, and correlate transactions across distributed environments.
Types of Node.js profiling & monitoring tools
Optimize your node.js code with the appropriate performance monitoring tools to efficiently pinpoint functionality issues, eliminate bottlenecks, and ultimately enhance the user experience. Get familiar with various node.js profiling & monitoring tools to determine which are the most suitable for your project and why.
Standard node.js profilers:
Standard profilers record stack traces of your application and monitor various elements including CPU, frequency of method calls, memory usage, and time spent per line of code. Reviewing the metrics obtained through sampling makes it easier to identify performance issues and allows you to dive deeper into relevant data, which expedites the troubleshooting process and provides a clearer picture of the health of your application.
Node.js tracing profilers:
Tracing profilers offer a more hands-on approach since developers must actively record tracing information directly into the code. Tracing profilers can measure call times, memory usage, and object allocations and offer more precise measurements than standard profilers. Although cost effective and easy to set up, the abundance of data returned with tracing profilers can potentially slow your application down.
Application performance management tools are a comprehensive solution for pinpointing performance issues down to the specific line of code responsible for functionality issues. APM tools improve the visibility of even the most complex infrastructures, including cloud and microservices, and can track everything from user journeys to server health.
Why AppDynamics for Node.js performance monitoring
Gain better awareness through data:
Node.js monitoring offers a more comprehensive understanding of your application through metrics that highlight any inefficiencies or performance issues within your program or infrastructure. Streamline the troubleshooting process with dynamic baselining, flame graphs, code-level diagnostics, and Virtual War Room collaboration to rapidly diagnose and address issues that affect the user experience or business outcomes.
Minimize downtime with real-time detection:
Detect errors and exceptions caused by application components in real-time, while running in a live production or development environment. The node.js profiler helps your team fix issues and proactively address exceptions with policy-based actions with Runbook Automation. Greater insight into heap activity related to object counts, size, and call graph allocation allows you to diagnose and solve memory leaks more quickly.
Monitor business transactions:
Gain a greater awareness of end-to-end transaction flows in complex or distributed environments with our transaction tag and follow feature. The AppDynamics Node.js Agent APIs make it possible to monitor business transactions performed outside of an HTTP request or on an application that exists within a device's memory versus the web.
Code-level monitoring within minutes:
The AppDynamics Node.js Agent allows for in-depth application monitoring without burdening resources. Drill into transaction snapshots to locate potential blocking code contributing to hot spots and slow methods. Review detailed call graphs that leverage automated code instrumentation and measure the total execution time and the percentage of total execution time of each method on the process's call stack.
Node.js supported environments
The node.js agent is compatible with the following operating systems and environments:
The agent is compatible with any Linux distribution based on glibc 2.5+
Mac OS X 10.8+ (Agent / Node.js version specific compatibility as noted)
Windows Server 2008R2+ and newer for 64 bit applications for Node.js versions 0.12.0 and higher (Agent / Node.js version specific compatibility as noted)
The 20.4.0 Node.js agent supports Node.js v8, v9, v10, v11, v12 and v13.
The 4.5.21+ Node.js agent supports Node.js v8, v9, v10, v11 and v12.
The 4.5.12+ Node.js agent supports Node.js v6, v7, v8, v9, v10, and v11. (v8, v9, v10, v11 on Mac).
The 4.5.11 Node.js agent supports Node.js v0.8, v0.10, v0.12, v4, v5, v6, v7, v8, v9, v10, and v11.
"In the 3 years I’ve had this job, there are several issues we’ve never been able to resolve. With AppDynamics, we fixed them in 2 hours."
