別のサーバーを自宅に設置する必要があったため、HomeAssistantが使用するホームスマートホームでそのパフォーマンスを監視することにしました。素早く思慮深いグーグルでは普遍的な解決策が得られなかったので、私は自分の自転車を作りました。
はじめに:プロセッサの負荷と温度、RAMとスワップの負荷、空きディスク容量、稼働時間、システムの総負荷、スマートディスクの温度と状態、およびレイドの状態(ubuntuサーバー20を搭載したサーバー上)を個別に監視します。簡単なソフトウェアraid1が発生しました)..。WD Greenドライブ、atom525を内蔵したGA-525マザーボード。
mosquittoブローカーはすでにスマートホームサーバーにセットアップされているため、データ転送方法としてmqttが選択されました。
この作業の最初のセクションでは、適用されるデータ収集方法の原則を示し、最後に、データ転送スクリプトとHA設定を示します。
例のすべてのコマンドはrootとして実行されます。

システムセンサーの読み取り値
内蔵センサーを入手するには、センサーユーティリティを使用します
インストールされていない場合は、次のように入力します。 apt-get install lm-sensors
まず、利用可能なすべてのセンサーを見つける必要があります。コマンドを実行し、すべての質問にsensors-detect
答えますy。その後、何が起こったのかを見ることができます。sensors
個人的には、私のセンサーは再起動後にのみ見つかったすべてのセンサーを表示し始めたことに注意する必要があります。多分ある種のバグ、私は知りません。

スクリーンショットは、議論されたサーバーがnextcloudのために計画されていることを示しています。その内部インジケーターもHAに完全に追加できます。これには、すばらしいAPIがあります。また、HAには統合機能が組み込まれています。
