Keymetrics develops monitoring for Node.js server infrastructure around the open source PM2 process manager. PM2 Plus provides a web interface for production monitoring, with issue and exception tracking, deployment reporting, real-time logs, custom metrics and actions, and notifications by email, Slack, or webhook. Its views bring applications and databases together in real time or across history, and can show an aggregate picture across applications. When an error occurs, the issue dashboard can show its time, affected servers, stack trace, code line, and logs from before the error. Node.js applications can publish values, counters, meters, and histograms through the @pm2/io library. PM2 Enterprise is aimed at high-scale or critical Node.js services. It adds configurable dashboards, threshold-based alerts, stored logs, and CPU and memory profiling that can be launched in production. Enterprise is offered as an installable on-premise system or through dedicated or managed instances. Runtime is listed as free at 0.00 USD and includes the process manager, zero-downtime reloads, terminal monitoring, and a real-time web interface. Plus is listed at 79.00 USD per month, with process limits; the pricing note says from $39/mo. Keymetrics lists API, Linux, self-hosted, and web platforms, with a hybrid deployment model.
