N8N Monitor

What This Skill Does

The N8N Monitor skill is a specialized operational utility designed for administrators managing N8N workflows via Docker containers. Developed by smitti7971, this skill functions as an automated bridge between the OpenClaw AI agent and your local Docker environment. It provides real-time visibility into your N8N infrastructure by executing native Docker commands to query system health, resource consumption, and event history. Rather than manually logging into a server terminal, users can query the agent to obtain structured reports on CPU and memory utilization, review the last 50 lines of system logs to troubleshoot workflow errors, or confirm that the N8N health check is passing. By standardizing the output into clear Markdown tables, this skill transforms raw CLI data into actionable operational intelligence.

Installation

To integrate this skill into your OpenClaw environment, execute the following command in your terminal: clawhub install openclaw/skills/skills/smitti7971/n8n-monitor Ensure that your OpenClaw agent has the necessary Docker socket permissions to execute command-line requests on the host machine where your N8N instance is running.

Use Cases

• Proactive Maintenance: Periodically ask the agent for resource stats to identify memory leaks in complex N8N workflows.
• Rapid Troubleshooting: Immediately pull the latest container logs when a workflow execution fails to pinpoint HTTP errors or database timeouts.
• Infrastructure Auditing: Validate the uptime and health status of your N8N service as part of a daily automated diagnostic routine.

Example Prompts

1. "Check the current health status of my n8n container and tell me if it is ready for traffic."
2. "Show me the last 50 lines of logs for the n8n container to see why my recent webhook failed."
3. "Analyze the current resource usage of the n8n container and let me know if it is consuming too much RAM."

Tips & Limitations

• Permissions: The agent must have appropriate permissions to interact with the Docker daemon; ensure the user running OpenClaw is in the 'docker' group.
• Container Naming: This skill expects the container name to be 'n8n'. If your deployment uses a different name, you may need to adjust the command references.
• Read-Only: This skill is strictly for monitoring; it does not support restarting, pausing, or updating the container. It is a read-only observability tool designed to keep your environment secure.
