10. Prometheus (and Grafana)
Prometheus is an open-source monitoring and alerting set of tools built by SoundCloud's engineers in 2012. It was the second CNCF project after Kubernetes, and it has managed to obtain a large and vibrant community of contributors and users ever since.
Grafana is a free, open-source software for data visualization. It is a powerful and feature-rich tool for exploring, creating, and sharing dashboards across teams. Connecting Prometheus and Grafana is not a must, but this tandem is often adopted.
Sentry offers a Node error and performance monitoring tool capable of discovering and monitoring performance-related issues, errors, and bottlenecks. It supports Node.js, Express, and KOA with SDKs for instrumentation. Sentry identifies issues and observes the application with end-to-end distributed tracing and performs an efficient root-cause analysis.
AppOptics offers comprehensive performance monitoring for both on-premises and highly distributed, cloud-based applications. It combines dashboards to visualize metrics from applications and infrastructure in one place and offers consolidated monitoring for all servers, host, containers, and serverless environments.
Bugsnag enables error reporting for Node.js applications. It automatically captures both handled and unhandled errors and helps to evaluate their impact.
It also enables basic alerting features via integrations with email, Slack, or Pagerduty and data visualization using dashboards.
Nowadays, APM is essential for delivering a reliable and successful, modern application in a sustainable fashion. Many SaaS solutions offer automated features for easier deployment and maintenance.
Most of the solutions offer a trial period ranging from 15 to 30 days, so you can get your hands on multiple solutions before subscribing and find out which works best with your stack.
Open-source tools, on the other hand, bring in a lot of freedom and customizability. However, they often cause additional toil related to deployment and maintenance and also unexpected infrastructure costs.
