為了掌握伺服器的即時系統資訊及網路流量，只能盯著那個醜到爆、看到膩的 MRTG 嗎？ 現在你可以有新的選擇，再也不必再委曲自己了！ 為了監控系統的負載狀態跟資源的使用狀況，我們曾經實作 系統資源監控 MRTG 篇、系統資源監控 Monitorix 篇、流量監控不求人，第一次安裝 Cacti 就上手 來取得這些資料。 可是： * MRTG 非常穩定，但是能提供的資訊實在有限，而且介面設計還是停留在一、二十年前的 Web 1.0 風格。 * Monitorx 提供的資料比 MRTG 更多，介面也還算美觀，但是在系統回饋的反應速度卻略嫌慢了一點。 * Cacti 功能多，能提供的資訊也多，可是不好架，服務老是起不來。 說巧不巧，偶然的機會看到網友分享了 Netdata 這個 Github 專案。 不試不知道，試了嚇一跳！ 連上了

在Twitter上偶然看到一張很漂亮的動態監控圖，查看之後才知道是由一款名爲netdata的開源工具實現，獲取實時(秒級)數據並用動態圖表展示，數據從/proc相關文件獲取(Linux中一切皆文件，內核將硬件虛擬成文件來進行管理)。 Introduction netdata代碼發佈在GitHub上。 以下是相關文檔 Prerequisites netdata依賴一些包，如make、gcc、autoconf、autogen、automake、pkg-config、git等。 git可使用yum安裝，也可參考本人的Compile Install And Configure Git On CentOS7通過源碼編譯安裝。 執行如下命令安裝依賴包 sudo yum install -y libuuid libuuid-devel zlib zlib-devel gcc make autoconf automake pkgconfig #根據個人情況使用 sudo yum install -y git Node
