prometheus 安装 node_exporter

本文主要是介绍prometheus 安装 node_exporter，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1，Ubuntu 16.04安装prometheus

• prometheus-2.18.1.darwin-amd64.tar.gz

# tar -zxvf prometheus-2.18.1.linux-amd64.tar.gz

• 设置环境变量
• vim /root/.bashrc

#prometheus
export PATH=$PATH:/root/prometheus-2.18.1.linux-amd64

2，测试启动

prometheus --config.file=/root/prometheus-2.18.1.linux-amd64/prometheus.yml

• 0.0.0.0:9090

2.1，运行前检查配置文件

# ./promtool check config prometheus.yml
Checking prometheus.ymlSUCCESS: 0 rule files found

2.2，修改prometheus.yml获取监控数据

• vim prometheus.yml增加job_name

scrape_configs:# The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.- job_name: 'prometheus'# metrics_path defaults to '/metrics'# scheme defaults to 'http'.static_configs:- targets: ['localhost:9090']# node_exporter- job_name: 'node'static_configs:- targets: ['127.0.0.1:9100']

2.3，prometheus开机启动

# vim /lib/systemd/system/prometheus.service

# cat /lib/systemd/system/prometheus.service
[Unit]
Description=prometheus service[Service]
User=root
ExecStart=/root/prometheus-2.18.1.linux-amd64/prometheus --config.file=/root/prometheus-2.18.1.linux-amd64/prometheus.ymlTimeoutStopSec=10
Restart=on-failure
RestartSec=5[Install]
WantedBy=multi-user.target

# systemctl daemon-reload
# systemctl enable prometheus.service
Created symlink /etc/systemd/system/multi-user.target.wants/prometheus.service → /lib/systemd/system/prometheus.service.
# systemctl start prometheus.service
# systemctl status prometheus.service

3，node_exporter安装

• node_exporter-1.0.0.linux-amd64.tar.gz

# tar -zxvf node_exporter-1.0.0.linux-amd64.tar.gz
# cd node_exporter-1.0.0.linux-amd64/
# ./node_exporter

• 访问ip:9100
  
• 增加配置prometheus
• vim prometheus.yml

  - job_name: 'node'static_configs:#- targets: ['localhost:9090']- targets: ['127.0.0.1:9100']

3.1，node_exporter开机启动

# cat /lib/systemd/system/node_exporter.service
[Unit]
Description=node_exporter service[Service]
User=root
ExecStart=/root/node_exporter-1.0.0.linux-amd64/node_exporterTimeoutStopSec=10
Restart=on-failure
RestartSec=5[Install]
WantedBy=multi-user.target

# systemctl daemon-reload
# systemctl enable node_exporter.service
# systemctl start node_exporter.service
# systemctl status node_exporter.service

3.1，监控多个主机

• 192.168.0.3 只运行node_exporter
• 192.168.0.2 运行有prometheus
• 配置prometheus.yml
• targets配置多个IP地址

# cat prometheus.ymlstatic_configs:- targets: ['localhost:9090']# node_exporter- job_name: 'node'static_configs:- targets: ['127.0.0.1:9100','192.168.0.3:9100']

4，prometheus查看targets

5，数据可视化显示

5.1，Grafana导入面板

• id为8919
• 数据源选择prometheus
