使用Prometheus监控Padavan路由器
Prometheus监控Padavan路由器
1、背景
近期在Synology（群辉）中安装一套Prometheus监控程序，目前已经监控Synology，然后家中有有路由器（Padavan）型号，也准备使用Prometheus+Grafan进行监控。
环境：
Prometheus：2.48.0
Grafan：10
Padavan：固件版本:3.4.3.9-099_22-05-1
2、监控步骤
1、padavan_exporter 正确使用
地址：https://github.com/Bpazy/padavan_exporter/blob/master/README-zh_CN.md
padavan_exporter有两种方式（不是放到Padavan系统上的）
- 安装到Linux操作系统，通过ssh连接到路由器进行数据获取
- 安装到Docker上，通过ssh连接到路由器进行数据获取
Linux操作系统
在Linux操作系统下载padavan_exporter
参数使用
$ ./padavan_exporter --help
Flags:
--help Show context-sensitive help (also try
--help-long and --help-man).
--web.listen-address=":9100" Address on which to expose metrics and web
interface
--padavan.ssh.host="127.0.0.1:22"
Padavan ssh host
--padavan.ssh.username="admin"
Padavan ssh username
--padavan.ssh.password="admin"
Padavan ssh password
--debug Debug mode
安装 padavan_exporter 并使用正确的参数启动（点击跳转项目首页）
wget https://github.com/Bpazy/padavan_exporter/releases/download/v0.0.2/padavan_exporter-linux-amd64-v0.0.2
sudo mv ./padavan_exporter-linux-amd64-v0.0.2 /usr/local/bin/padavan_exporter
sudo chmod u=rwx,o=rx,g=rx /usr/local/bin/padavan_exporter
sudo chgrp root /usr/local/bin/padavan_exporter
sudo chown root /usr/local/bin/padavan_exporter
# 自定义 systemd service
sudo touch /lib/systemd/system/padavan_exporter.service
sudo cat <<EOF >/lib/systemd/system/padavan_exporter.service
[Unit]
Description=Node exporter
After=network.target
[Service]
Type=simple
ExecStart=/usr/local/bin/padavan_exporter --padavan.ssh.host="127.0.0.1:22" --padavan.ssh.username="admin" --padavan.ssh.password="admin"
Restart=on-failure
[Install]
WantedBy=multi-user.target
EOF
# 加载自定义的 service
sudo systemctl daemon-reload
# 开机自启
sudo systemctl enable padavan_exporter
# 启动
sudo systemctl start padavan_exporter
Docker Compose（推荐）
当然更好的方式是使用 Docker Compose，你可以参考本项目预置的 docker-compose.yml 文件。
此处要注意，我把9100端口 映射到 9101，因为 我的 9100端口已经被占用，你们要注意
version: '3'
services:
padavan_exporter:
image: bpazy/padavan_exporter:latest
restart: always
ports:
- "9101:9100"
command: ["--padavan.ssh.host=192.168.123.1:22", "--padavan.ssh.username=admin", "--padavan.ssh.password=admin"]
测试数据
Prometheus修改配置重载
- job_name: 'padavan'
static_configs:
- targets: ['192.168.123.200:9101']
2、Grafana 导入图形
这个图在Dashboard: https://grafana.com/grafana/dashboards/15978 进行修改 根补充
如果导入没数据，请编辑
然后在Prometheus上进行调试
下载Json文件导入
Padavan-1701611865144.json
