APIでMist SLEとインサイトを使用する
RESTful APIを使用して、ネットワークパフォーマンスに関するインサイトを取得します。
Juniper Mistポータルを使用してネットワークの動作を監視すると、問題になる前に何が起こっているかについてのインサイトが得られます。ネットワークを無線、有線、WANなど、複数の視点から見ることができます。さらに、Juniper Mist™ が提供するツールを使用して、潜在的な問題のトラブルシューティングと修正を行うことができます。
[Monitor > Service Levels] のプライマリ Mist ダッシュボードには、予測分析と相関エンジン (PACE) の結果がサービス レベル期待値 (SLE) メトリックの形式で表示されます。SLEは、Juniper Mistクラウドで機械学習とMist PACEを活用します。SLEは、これらのリソースを使用して、アクセスポイント(AP)からのストリーミングテレメトリを、エンドユーザーのネットワークエクスペリエンスをほぼリアルタイムで視覚化したものに変換します。SLEについて詳しくは、Juniper Mist AIネイティブ運用ガイドをご覧ください。
Mist GUIに表示されるすべてと同様に、SLEとインサイト情報もAPIから利用できます。
SLE
特定のSLEに関する情報を収集して、履歴レポートやその他の自動化に使用したりするのに役立ちます。他の API 呼び出しと同様に、まず、データを収集するエンドポイントを決定します。以下は、 getOrgsSitesSle エンドポイントに対する API GET リクエストの例です。
GET
/api/v1/orgs/{org_id}/insights/sites-sle
手記：{org_id} を組織 ID に置き換えます。
詳細については、 SLEの概要を参照してください。
洞察 力
インサイトは、サイト全体、アクセスポイント、または無線クライアントにわたるネットワークエクスペリエンスの概要を提供します。サイトを確認するときに始めるのに最適な場所です。
Insight 情報は、次のいずれかの Insights エンドポイントに対して GET リクエストを行うことで検索できます。
- GetSiteInsightMetrics(英語)
- GetSiteInsightMetricsForDevice
- GetSiteInsightMetricsForClient
詳細については、「 Insights の概要」をご参照ください。
メトリックと分類子
Juniper Mist SLEとInsightsエンドポイントは、メトリックと分類子をサポートします。メトリックは、サービスレベルが設定されたしきい値を満たしているかどうかを追跡します。メトリックがしきい値を満たしていない場合、この障害は、障害が発生した場所をさらに理解するために、分類子の 1 つに起因する可能性があります。
SLE と Insights のエンドポイントでは、多くの場合、 metric 引数が必要です。これは、生の統計情報や設定に加えて、Mist内部データ分析から得られた計算値が公開されるためです。Mist では、新しいデータ分析機能が追加されるたびに一意の API 関数を作成するのではなく、ほんの一握りの関数を公開しますが、 metric 引数を使用して取得する派生データ値を指定します。
分析情報メトリックの一覧を取得するには、次の GET 呼び出しを発行します。
GET
/api/v1/sites/{site_id}/insights/{metric}

SLEの割合の計算
SLEメトリックの成功率は、選択した期間にしきい値が満たされた頻度の割合として計算されます。分類子もパーセンテージとして計算されますが、これらの値は親の障害に対する影響を示します。
たとえば、次のスクリーンショットは、接続時間が 96% の確率で成功したことを示しています。午後 3:00 から 4:00 の間に接続に成功したすべてのクライアントは、4 秒のしきい値内に接続プロセスを完了しました。
このメトリクスの成功率(%)は、「Metric Summary」APIエンドポイントから導き出されます。

メトリクスの失敗率は、失敗 (sle.samples.degraded) を合計 (sle.samples.total) で割ることによって計算されます。これは、成功率のパーセンテージに変換されます。上記の API 応答ペイロードを使用すると、計算は次のようになります。
ceil(1-[(0.0+0.0+3.0+0.0+3.0+0.0)/(19.0+14.0+34.0+8.0+20.0+43.0)])*100= ceil(1-[6/138])*100= ceil(1-0.04347826086)*100= ceil(0.95652173914)*100= 0.96*100= =96%

分類子の影響は、分類子のエラー (classifiers[n].samples.degraded) をすべてのエラーの合計 (classifiers[].samples.degraded) で割ることによって計算されます。これはパーセンテージに変換されます。上記の API 応答ペイロードを使用すると、DHCP の計算は次のようになります。
ceil([0+0+0+0+1.0+0]/[(0+0+0+0+1.0+0)+(0+0+0+0+0+0)+(0+0+3.0+0+1.0+0)+(0+0+0+0+1.0+0)])*100= ceil(1/[1.0+0+4.0+1.0])*100= ceil(1/6)*100= ceil(0.16666666666)*100= 0.17*100= =17%
SLEの監視
SLE データは 10 分ごとに更新されます。ただし、この細分度で監視するとSLEが変動しやすくなります。したがって、明示的な開始時刻と終了時刻を使用して 1 時間間隔でクエリを実行し、1 時間に 1 回のみポーリングすることをお勧めします。
