[New feature] Node VM in Site24x7 APM Insight Node.js agent

We are excited to announce that the APM Insight Node.js agent now supports Node VM.

Node VM is a native node add-on that uses Google Chrome's V8 engine to collect memory, CPU, garbage collection, and event loop stats. With these metrics, you can gain insight into useful runtime data for troubleshooting performance issues and monitoring your application's health.

To view Node VM metrics, you can navigate to APM > your Node.js application > Node VM tab.

The collected metrics are displayed as graphs, which can be used to troubleshoot performance issues.

For example:
  • Memory usage increases when the application starts using more objects and when garbage collection starts runs more frequently. On the other hand, this increases CPU utilization.
  • Excessive synchronous code execution may result in higher CPU utilization. This will result in spikes on the Max CPU time per tick chart.

Happy monitoring,
The Site24x7 team
