RPi-Monitor簡介
前文 講到如何通過一個shell腳本獲取CPU狀態和PMU溫度，而RPi-Monitor基於perl，內置webserver，通過優化后對sd卡占用更少。由於其極強的可定制性與拓展性，你可以換用熟悉的Web Server，顯示服務狀態，甚至作為視頻監控。最早是基於樹莓派的項目，后來在XApple社區發現有人移植到蓮霧派，今天cnx-software也報道了，特此記錄下來。之前都是使用的phpsysinfo

安裝配置
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
安裝升級RPi-Monitor

nano /etc/rpimonitor/template/lemaker_guitar.conf
添加以下內容，創建主配置文件，根據自己需要啟用|禁用模塊：

創建軟鏈接：
ln -sf /etc/rpimonitor/template/lemaker_guitar.conf /etc/rpimonitor/data.conf
重啟rpimonitor服務
systemctl start rpimonitor
訪問網頁前端
假如Guitar的IP為192.168.1.111,那么在瀏覽器里輸入192.168.1.111:8888 即可打開狀態頁面。經過配置可以遠程訪問Guitar之后，無論身處何地都可以及時監控Guitar的運行狀態。
軟件使用GPL3 協議，所以可以對界面進行一些改造。
自定義功能與添加模塊
使用配置文件生成助手
2.6版本之后引入了一個新工具：RPi-Monitor交互式配置文件生成助手 (RPi-Monitor Interactive Configuration Helper),通過運行
rpimonitord -i
可以非常方便地創建自己的監視點。Via
添加傳感器數據
以DHT溫濕度傳感器為例，可以監視溫濕度變化，繪制折線圖，修改之后可以顯示諸多傳感器數值。Via
使用標簽顯示狀態
2.7版本之后引入標簽顯示服務狀態的功能，支持6種顏色：
效果如圖所示：
根據模板修改/etc/rpimonitor/template/services.conf文件即可。稍加改造可以實現更多功能。
注意：最新2.10版/etc/rpimonitor/template/services.conf文件最后一行少一個")",需要自己補上。
nano中可通過Ctrl+E快速跳至行尾。Via
