PM2 Server Monitor

pm2-server-monit is a PM2 module designed to automatically monitor crucial server vital signs, integrating seamlessly into the PM2 ecosystem for process management. It tracks key metrics such as CPU average usage, free and used memory, drive space, network speed (input/output), total opened files, running processes, and active TTY/SSH sessions. The current stable version is 3.0.0. While no explicit release cadence is documented, the jump from v2.0 to v3.0 suggests periodic updates incorporating significant feature enhancements or internal changes. Its primary differentiator is its deep integration with PM2, allowing server monitoring to be managed and viewed alongside application processes, making it particularly useful for environments already leveraging PM2 for their Node.js applications. Unlike standalone monitoring agents, pm2-server-monit leverages the PM2 daemon to collect and report system statistics.
