Keymetrics review
A focused Node.js monitoring suite with real-time visibility and enterprise tracing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Keymetrics provides web-based application and server monitoring for Node.js applications managed with PM2. PM2 Runtime is the open-source Node.js process manager, with zero-downtime reloads plus terminal and real-time web monitoring. PM2 Plus adds issue and exception tracking, custom application metrics, logs, email and Slack notifications, server health monitoring, and custom actions triggered in applications. It is aimed at teams that need operational visibility around Node.js services rather than a broad, language-neutral monitoring product.
Pricing is structured around the PM2 product line. PM2 Plus starts at $39 per month with monthly billing and has a 14-day free trial; the published plans show no free plan. Its paid capabilities center on web-based monitoring, application data, alerts, logs, and server health. PM2 Enterprise adds CPU and memory profiling, transaction tracing, distributed tracing across services, advanced rule-based alerting, custom dashboards, long-term data retention, and cloud shared or on-premise installation. Teams should choose PM2 Plus for core Node.js monitoring and move to Enterprise when deeper performance analysis, retention, or deployment control is required.
The platform supports web and self-hosted deployment, with integrations including Slack, Email, Webhook, Prometheus, Go, and Python. Its strongest fit is a PM2-managed Node.js environment where runtime monitoring, exception tracking, metrics, logs, and notifications belong in one workflow. Enterprise also broadens the operational view through profiling, tracing, custom dashboards, and rule-based alerts. Organizations seeking a multi-language APM product or advanced capabilities without moving to an Enterprise tier should consider a different option; Keymetrics is more appropriate for Node.js teams that value PM2-centered monitoring and hybrid deployment.
