What is PM2 Process Manager?
The PM2 skill enables developers to manage Node.js applications in production environments using Openclaw Skills. It provides a robust set of tools for starting, monitoring, and maintaining high availability for web servers and background tasks. By integrating this skill, users can ensure their services remain operational through crashes, server reboots, and high-traffic scenarios using cluster mode, providing a seamless operational layer for modern web development.
PM2 Process Manager Use Cases
- Using Openclaw Skills to deploy production Node.js or Next.js applications.
- Automating application restarts after server reboots using saved process lists.
- Monitoring real-time resource usage and application logs across multiple services.
- Managing environment variables and ports for different deployment stages.
- Scaling applications across multiple CPU cores without downtime.
How PM2 Process Manager Works
- Install the PM2 daemon globally using the package manager within your environment.
- Initialize an application using the start command or a structured ecosystem configuration file.
- Monitor process status and application logs using the integrated CLI dashboard.
- Configure persistent startup scripts to ensure Openclaw Skills apps persist after system restarts.
- Execute zero-downtime reloads to update application code without interrupting user traffic.

PM2 Process Manager Data Schema & Taxonomy
PM2 manages process state and metadata via internal databases and optional configuration files. Openclaw Skills users typically define applications using an ecosystem file:
| Property | Type | Description |
|---|---|---|
| name | String | The unique identifier for the process |
| script | String | The script path or command to execute (e.g., 'npm') |
| args | String | Arguments passed to the execution script |
| env | Object | Environment variables for production or development |
| watch | Boolean | Enables automatic restart on file changes |
PM2 Process Manager Advanced Features
- Cluster Mode: Automatically scale applications across all available CPU cores to maximize performance.
- Watch & Restart: Real-time monitoring of file changes to trigger automatic process updates.
- Memory Thresholds: Configure automatic restarts when a process exceeds a defined memory limit (e.g., --max-memory-restart 300M).
- Cron Scheduling: Schedule restarts or maintenance tasks using standard cron syntax via Openclaw Skills.
- Real-time Monitoring: Access an interactive dashboard with the monit command to visualize resource consumption.
