在 Azure 監視器中建立計量警示規則的 Resource Manager 範本範例

  • 發行項

本文提供如何使用 Azure Resource Manager 範本在 Azure 監視器中設定計量警示規則的範例。 每個範例都包含範本檔案和參數檔案，且附有要提供給範本的範例值。

注意

如需 Azure 監視器的可用範例清單，以及在 Azure 訂用帳戶中的部署指引，請參閱 Azure Resource Manager 範例。

如需可用於計量警示規則的資源清單，請參閱 Azure 監視器中計量警示所支援的資源。 您可以在計量警示 - 建立或更新中取得警示規則的結構描述和屬性說明。

注意

用於為資源類型 Azure Log Analytics 工作區 (即) Microsoft.OperationalInsights/workspaces 建立計量警示的資源範本，需要額外的步驟。 如需詳細資訊，請參閱記錄的計量警示 - 資源範本。

多個準則、靜態閾值

計量警示支援多維度計量警示，而且每個警示規則可具有最多 5 個準則。 下列範例會建立維度計量的計量警示規則，並指定多個準則。

在包含多個準則的警示規則中使用維度時，會套用下列限制：

  • 在每個準則中，您只能為每個維度選取一個值。

  • 您不能使用 "*" 作為維度值。

  • 當不同準則中設定的計量支援相同的維度時，則必須針對相關準則中的所有這些計量，以相同方式明確設定已設定的維度值。

    • 在下列範例中，因為 Transactions 和 SuccessE2ELatency 計量都有 ApiName 維度，而且 criterion1 為 ApiName 維度指定了 "GetBlob" 值，所以 criterion2 也必須要為 ApiName維度設定 "GetBlob"值。

多個維度、靜態閾值

單一警示規則可以一次監視多個計量時間序列，如此可管理較少的警示規則。 下列範例會建立維度計量的靜態計量警示規則。

在此範例中，警示規則會監視 ResponseType 的維度值組合，以及 Transactions 計量的 ApiName 維度：

  1. ResponsType - 若使用 "*" 萬用字元，表示針對 ResponseType 維度的每個值 (包括未來的值)，分別監視不同的時間序列。
  2. ApiName - 只針對 GetBlob 和 PutBlob 維度值監視不同的時間序列。

例如，此警示規則所監視的幾個可能時間序列為：

  • Metric = Transactions，ResponseType = Success，ApiName = GetBlob
  • Metric = Transactions，ResponseType = Success，ApiName = PutBlob
  • Metric = Transactions，ResponseType = Server Timeout，ApiName = GetBlob
  • Metric = Transactions，ResponseType = Server Timeout，ApiName = PutBlob

  }
}

注意

使用 "All" 作為維度值相當於選取 "*" (所有目前和未來的值)。

多個維度、動態閾值

單一動態閾值警示規則可一次為數百個計量時間序列 (甚至不同類型) 建立合適的閾值，讓需要管理的警示規則變少。 下列範例會建立維度計量的動態閾值計量量警示規則。

在此範例中，警示規則會監視 ResponseType 的維度值組合，以及 Transactions 計量的 ApiName 維度：

  1. ResponsType - 針對 ResponseType 維度的每個值 (包括未來的值)，都會分別監視不同的時間序列。
  2. ApiName - 只針對 GetBlob 和 PutBlob 維度值監視不同的時間序列。

例如，此警示規則所監視的幾個可能時間序列為：

  • Metric = Transactions，ResponseType = Success，ApiName = GetBlob
  • Metric = Transactions，ResponseType = Success，ApiName = PutBlob
  • Metric = Transactions，ResponseType = Server Timeout，ApiName = GetBlob
  • Metric = Transactions，ResponseType = Server Timeout，ApiName = PutBlob

注意

使用動態閾值的計量警示規則目前不支援多個準則。

自訂計量、靜態閾值

您可以使用下列範本，針對自訂計量建立更進階的靜態閾值計量警示規則。

若要深入了解 Azure 監視器中的自訂計量，請參閱 Azure 監視器中的自訂計量。

在為自訂計量建立警示規則時，您必須指定計量名稱和計量命名空間。 應確定自訂計量已回報，因為若自訂計量不存在，您就無法建立警示規則。

注意

您可以透過 Azure 入口網站瀏覽自訂計量，來找到特定自訂計量的計量命名空間

多個資源

針對存在於相同 Azure 區域中的資源，Azure 監視器支援使用單一計量警示規則來監視多個相同類型的資源。 目前只有 Azure 公用雲端才支援這項功能，且僅適用於虛擬機器、SQL 伺服器資料庫、SQL 伺服器彈性集區和 Azure Stack Edge 裝置。 此外，這項功能僅適用於平台計量，且不支援自訂計量。

動態閾值警示規則也可一次為數百個計量序列 (甚至不同類型) 建立合適的閾值，讓需要管理的警示規則變少。

針對以單一規則監視多個資源的功能，本節將說明三種此類案例適用的 Azure Resource Manager 範本。

  • 監視一個或多個資源群組中的所有虛擬機器 (位於一個 Azure 區域)。
  • 監視一個訂用帳戶中的所有虛擬機器 (位於一個 Azure 區域)。
  • 監視一個訂用帳戶中的一系列虛擬機器 (位於一個 Azure 區域)。

注意

  • 在監視多個資源的計量警示規則中，只允許一個準則。
  • 若您要為單一資源建立計量警示，範本會使用目標資源的 ResourceId。 若您要為多個資源建立計量警示，範本會使用目標資源的 scope、TargetResourceType 和 TargetResourceRegion。

使用計量警示的可用性測試

Application Insights 可用性測試可協助您從全球各地的不同位置，監視您網站/應用程式的可用性。 可用性測試警示會在特定幾個位置中的可用性測試失敗時，向您發出通知。 可用性測試警示與計量警示 (Microsoft.Insights/metricAlerts) 屬於相同資源類型。 下列範例會建立簡單的可用性測試和相關警示。

注意

& 是 & 的 HTML 實體參考。 URL 參數仍會以單一 & 來分隔，但如果您在 HTML 中提及 URL，則需要對其進行編碼。 因此，如果您的 pingURL 參數值中有任何 "&"，您就必須使用 "&" 來替代

參數檔案

  "contentVersion": "1.0.0.0",
  "parameters": {
    "appName": {
      "value": "Replace with your Application Insights resource name"
    },
    "pingURL": {

      "defaultValue": "Optional parameter that allows you to perform a content-match for the presence of a specific string within the content returned from a pingURL response",
      "type": "String"
    },
  }
}

content-match pingText 參數的其他設定是在範本檔案的 Configuration/Webtest 部分中控制的。 具體而言是下面區段：

<RuleParameter Name=\"FindText\" Value=\"',parameters('pingText'), '\" />
<RuleParameter Name=\"IgnoreCase\" Value=\"False\" />
<RuleParameter Name=\"UseRegularExpression\" Value=\"False\" />
<RuleParameter Name=\"PassIfTextFound\" Value=\"True\" />
