Announcement
Exporter for machine metrics
Prometheus exporter for hardware and OS metrics exposed by Unix kernels, providing essential visibility into server health and performance.
Project Introduction
Summary
The Node Exporter is a simple server that exposes machine-level metrics via HTTP for consumption by a Prometheus server. It is a crucial component for monitoring the health and performance of your infrastructure hosts.
Problem Solved
Provides a standardized and reliable way to expose system and hardware-level metrics from individual machines to a Prometheus monitoring system, addressing the need for consistent host-level observability.
Core Features
Comprehensive Metric Collection
Collects a wide range of host metrics (CPU, memory, disk I/O, network, etc.).
Simple Deployment
Easy to deploy as a single static binary on most Linux/Unix systems.
Lightweight and Efficient
Low resource consumption, suitable for production environments.
Tech Stack
使用场景
The Node Exporter is essential for any scenario requiring detailed monitoring of individual machine health and performance within a Prometheus ecosystem.
Scenario 1: Fleet-wide Server Monitoring
Details
Deploy Node Exporter on all servers in a fleet to monitor their CPU, memory, disk, and network usage centrally via Prometheus.
User Value
Provides unified visibility across all hosts, simplifies infrastructure health checks, and aids capacity planning.
Scenario 2: Performance Troubleshooting
Details
Analyze metrics from the Node Exporter (e.g., disk I/O wait, network packet drops) to pinpoint bottlenecks or issues on a specific server experiencing performance problems.
User Value
Offers granular system data necessary to diagnose root causes of performance degradation or system instability.
