n8n System Health Overview Dashboard

A Grafana dashboard providing real-time observability into the n8n Node.js runtime, system resources, event loop health, memory usage, CPU load, and process stability via Prometheus.

Overview

This dashboard focuses on low-level system and runtime metrics from n8n’s Prometheus endpoint.
It gives production operators a clear view of instance health and performance.

Features

Process & Instance Information

  • n8n version
  • Node.js version
  • Instance uptime (with thresholds)
  • Leader/follower role (cluster)
  • Active workflows

CPU & Event Loop Health

  • CPU breakdown (total/user/system)
  • Event loop latency percentiles (P50/P90/P99)

Memory & Heap Usage

  • RSS memory usage
  • Heap used vs total
  • Heap usage percentage

Garbage Collection & Runtime

  • GC duration by type
  • Open file descriptors
  • Max file descriptor limit

Requirements

Software

  • Grafana ≥ 8
  • Prometheus as datasource
  • n8n instance with Prometheus metrics enabled
