prometheus exporter 监控主机

Posted 2022-12-09 CIAS

前提要求部署Grafana

前言

有许多库和服务器可以帮助将第三方系统中的现有指标导出为Prometheus指标。在无法直接使用Prometheus度量(例如，HAProxy或Linux系统统计数据)对给定系统进行检测的情况下，这是非常有用的。

• node-exporter Linux操作系统采集（如CPU，内存，硬盘，网络等）
• wmi_exporter Windows操作系统采集（如CPU，内存，硬盘，网络等）
• Redis_exporter 数据库采集器
• mysql 数据库采集器
• SQL exporter 数据库采集器
• Prometheus 采集数据

Prometheus 一键安装

• 配置文件位置/usr/local/prometheus-2.37.2.linux-amd64/prometheus.yml
• Prometheus版本定义建议选择LTS长期支持版本
