grafana 监控 node
准备工作
安装 prometheus 和 grafana
参考文章：https://blog.csdn.net/weixin_42555971/article/details/125784517
prometheus 配置文件
- scrape_interval：刷新间隔时间，默认15秒
- external_labels：外部标签
- job_name：添加到此配置中删除的任何时间序列
- static_configs：配置监控地址，即普罗米修斯暴露地址
global:
scrape_interval: 15s # By default, scrape targets every 15 seconds.
# Attach these labels to any time series or alerts when communicating with
# external systems (federation, remote storage, Alertmanager).
external_labels:
monitor: 'codelab-monitor'
# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
# The job name is added as a label `job=` to any timeseries scraped from this config.
- job_name: 'prometheus'
# Override the global default and scrape targets from this job every 5 seconds.
scrape_interval: 5s
static_configs:
- targets: ['localhost:9090']
- job_name: 'service'
static_configs:
- targets: ['192.168.xx.x0:9100']
- targets: ['192.168.xx.x1:9100']
- targets: ['192.168.xx.x2:9100']
配置 grafana 数据大盘，可选择 12884 或 8919
节点安装 node_export
docker run -d -p 9100:9100 --restart=always -h house-name --name node-exporter prom/node-exporter
防火墙开放 9100 端口
systemctl start firewalld.service
firewall-cmd --zone=public --add-port=9100/tcp --permanent
systemctl restart firewalld.service
firewall-cmd --reload
