使用RPi-Monitor监控、统计Guitar的运行状态

前言

之前发在ickey社区上的一系列文章：

犹抱琵琶半遮面，无人知是荔枝来——unboxing & interview 一、二、三
葡萄美酒夜光杯，巧妇难为无米炊——资料与社区
一支穿云箭，板子要加散热片——系统监控与发热问题
念去去千里烟波，暮霭沉沉楚天阔——远程控制相关
竹喧归浣女，莲动小轻舟——延长板载eMMC寿命、优化性能

RPi-Monitor简介

前文讲到如何通过一个shell脚本获取CPU状态和PMU温度，而RPi-Monitor基于perl，内置webserver，通过优化后对sd卡占用更少。由于其极强的可定制性与拓展性，你可以换用熟悉的Web Server，显示服务状态，甚至作为视频监控。最早是基于树莓派的项目，后来在XApple社区发现有人移植到蓮霧派，今天cnx-software也报道了，特此记录下来。之前都是使用的phpsysinfo

安装配置

添加rpimonitor源

sudo -s
apt-get install apt-transport-https ca-certificates
wget https://raw.githubusercontent.com/XavierBerger/RPi-Monitor/master/init/apt/sources.list.d/rpimonitor.list -O /etc/apt/sources.list.d/rpimonitor.list
apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 2C0D3C0F

安装升级RPi-Monitor

apt-get update && apt-get install rpimonitor && apt-get upgrade

停止服务添加自定义模块

systemctl stop rpimonitor
nano /etc/rpimonitor/template/S500_ATC2603.conf

nano /etc/rpimonitor/template/lemaker_guitar.conf

添加以下内容，创建主配置文件，根据自己需要启用|禁用模块：

web.page.icon='img/logo.png'
web.page.menutitle='RPi-Monitor  <sub>('+data.hostname+')</sub>'
web.page.pagetitle='RPi-Monitor ('+data.hostname+')'
web.status.1.name=lemaker_guitar
web.statistics.1.name=lemaker_guitar
include=/etc/rpimonitor/template/version.conf
include=/etc/rpimonitor/template/uptime.conf
include=/etc/rpimonitor/template/S500_ATC2603.conf
include=/etc/rpimonitor/template/memory.conf
include=/etc/rpimonitor/template/swap.conf
include=/etc/rpimonitor/template/sdcard.conf
include=/etc/rpimonitor/template/network.conf
include=/etc/rpimonitor/template/wlan.conf

创建软链接：

ln -sf /etc/rpimonitor/template/lemaker_guitar.conf /etc/rpimonitor/data.conf

重启rpimonitor服务

systemctl start rpimonitor

访问网页前端

假如Guitar的IP为192.168.1.111,那么在浏览器里输入192.168.1.111:8888 即可打开状态页面。经过配置可以远程访问Guitar之后，无论身处何地都可以及时监控Guitar的运行状态。

软件使用GPL3 协议，所以可以对界面进行一些改造。

自定义功能与添加模块

使用配置文件生成助手

2.6版本之后引入了一个新工具：RPi-Monitor交互式配置文件生成助手 (RPi-Monitor Interactive Configuration Helper),通过运行

rpimonitord -i

可以非常方便地创建自己的监视点。Via

添加传感器数据

以DHT温湿度传感器为例，可以监视温湿度变化，绘制折线图，修改之后可以显示诸多传感器数值。Via

使用标签显示状态

2.7版本之后引入标签显示服务状态的功能，支持6种颜色：

效果如图所示：

根据模板修改/etc/rpimonitor/template/services.conf文件即可。稍加改造可以实现更多功能。

注意：最新2.10版/etc/rpimonitor/template/services.conf文件最后一行少一个")",需要自己补上。

nano中可通过Ctrl+E快速跳至行尾。Via
