7 Best Tools for Monitoring Node.js Servers

Read Time:3 Minute, 41 Second

Monitoring servers is always a controversial subject. It usually falls under system administration, and software engineers don’t even go near it, but we are losing one of the huge benefits of monitoring: the ability to react quickly to failures. By monitoring our system very closely, we can be aware of problems almost immediately so that the actions to correct the problem may even save us from impacting the customers.

There are several tools available for monitoring servers, but few are designed specifically for Node. In this post, we will discover the 7 best of them.

Express Status Monitor

Express.js is the de-facto framework of choice for Node.js developers. Express Status Monitor is an incredibly simple, self-hosted module, you add to your Express server. It exposes a /status route that reports real-time server metrics with the help of Socket.io and Chart.js.

Installing the tool from npm is as simple as this.

Enter fullscreen mode Exit fullscreen mode

After you have the module installed, you need to add it before any other middleware or router.

Enter fullscreen mode Exit fullscreen mode

Once you run your server go to the /status route to monitor your Node.js metrics.

Features of Express Status Monitor:

  • Status Code
  • Monitor response time
  • Request frequency
  • Memory and CPU utilization

New Relic

New Relic offers a Node.js quickstart for installing pre-configured observability solutions, including monitors for Apdex and CPU utilization and visualizes these metrics in informative dashboards, including also slowest transactions or throughput. New Relic also offers Service Maps, Error Analytics, code-level analysis, and real-time insights.

Features of New Relic

  • Key business transaction monitoring.
  • External services performance monitoring.
  • Availability and error monitoring.
  • End-to-end user monitoring through browser support.
  • Synthetic monitoring.

Clinic.js

Clinic.js includes three tools to help diagnose and pinpoint performance issues in Node.js applications. It’s surprisingly easy to use. All you need to do is install the module from npm and run it. This will generate reports for you that make troubleshooting much easier.

Features of clinic.js:

  • Collects metrics by injecting probes
  • Assess health and heuristics
  • Creates recommendations
