這是我第二篇文章有關於 Telegram 機器人，此機器人的功能極其簡單！監控伺服器的使用率，最近因為在伺服器又搞了一個很麻煩的東西，要時時刻刻注意有沒有異常。所以才寫了這個小程式（如圖）。
本文直接省略@BotFather產生機器人的說明，我想那應該不是問題。第一篇文章請參考：淺談Telegram開發機器人
本程式一旦運行，就不會停止，每隔固定幾秒鐘會自動更新訊息，會一直不斷的編輯，而不是一直送出（Telegram 有支持編輯訊息的功能）。直接上程式碼。這次使用Python，因為牽扯到系統，用 PHP 就不太適合了。

若在 Linux 的環境下，使用 tmux 輸入指令會比較好。因為它可以在背景運作，可以直接關掉 terminal。
