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 webinterface--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:latestrestart: alwaysports:- "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

Padavan

如果导入没数据，请编辑
在这里插入图片描述

然后在Prometheus上进行调试
在这里插入图片描述

下载Json文件导入
Padavan-1701611865144.json
