用于 Azure Monitor 指标警报规则的资源管理器模板示例

  • Artículo

本文提供了在 Azure Monitor 中使用 Azure 资源管理器模板配置度量警报规则的示例。 每个示例都包含模板文件和参数文件，其中包含要提供给模板的示例值。

注意

有关可用示例的列表以及在 Azure 订阅中部署这些示例的指南，请参阅 Azure Monitor 的 Azure 资源管理器示例。

有关可用于指标警报规则的资源列表，请参阅 Azure Monitor 中的指标警报支持的资源。 有关警报规则的架构和属性的说明，请参阅指标警报 - 创建或更新。

注意

用于针对资源类型创建指标警报的资源模板：Azure Log Analytics 工作区（即 Microsoft.OperationalInsights/workspaces）需要执行其他步骤。 有关详细信息，请参阅日志指标警报 - 资源模板。

多个条件，静态阈值

指标警报支持根据多维指标发出警报，每个警报规则最多 5 个条件。 以下示例将基于维度指标创建指标警报规则，并指定多个条件。

在包含多个条件的警报规则中使用维度时，以下约束适用：

  • 在每个条件内，只能为每个维度选择一个值。

  • 不能使用“*”作为维度值。

  • 当以不同条件配置的指标支持相同的维度时，必须以相同方式为相关条件下的所有这些指标显式设置已配置的维度值。

    • 在下面的示例中，由于 Transactions 和 SuccessE2ELatency 指标均具有 ApiName 维度，并且 criterion1 为 ApiName 维度指定了“GetBlob”值，因此，criterion2 也必须为 ApiName 维度设置“GetBlob”值。

多个维度，静态阈值

单个警报规则可以一次监视多个指标时序，从而减少了要管理的警报规则。 以下示例将基于维度指标创建静态指标警报规则。

在此示例中，警报规则监视 Transactions 指标的 ResponseType 和 ApiName 维度的维度值组合：

  1. ResponsType - 使用“*”通配符意味着对于 ResponseType 维度的每个值（包括将来的值），将分别监视不同的时序。
  2. ApiName - 只对“GetBlob”和“PutBlob”维度值监视不同的时序 。

例如，该警报规则监视的几个潜在时序是：

  • Metric = 事务、ResponseType = 成功、ApiName = GetBlob
  • Metric = 事务、ResponseType = 成功、ApiName = PutBlob
  • Metric = 事务、ResponseType = 服务器超时、ApiName = GetBlob
  • Metric = Transactions，ResponseType = Server Timeout，ApiName = PutBlob

    }
  }
}

注意

使用“All”作为维度值等效于选择“*”（所有当前和未来值）。

多个维度，动态阈值

单个动态阈值警报规则可以一次为数百个指标时序（甚至不同类型）创建定制阈值，从而减少需要管理的警报规则。 以下示例将基于维度指标创建动态阈值指标警报规则。

在此示例中，警报规则监视 Transactions 指标的 ResponseType 和 ApiName 维度的维度值组合：

  1. ResponsType - 对于 ResponseType 维度的每个值（包括将来的值），将分别监视不同的时序。
  2. ApiName - 只对“GetBlob”和“PutBlob”维度值监视不同的时序 。

例如，该警报规则监视的几个潜在时序是：

  • Metric = 事务、ResponseType = 成功、ApiName = GetBlob
  • Metric = 事务、ResponseType = 成功、ApiName = PutBlob
  • Metric = 事务、ResponseType = 服务器超时、ApiName = GetBlob
  • Metric = 事务、ResponseType = 服务器超时、ApiName = PutBlob

注意

使用动态阈值的指标警报规则目前不支持多个条件。

多个资源

对于同一 Azure 区域中的资源，Azure Monitor 支持使用单个指标警报规则监视相同类型的多个资源。 此功能目前仅在 Azure 公有云中受支持，并且仅适用于虚拟机、SQL Server 数据库、SQL Server 弹性池和 Azure Stack 边缘设备。 此外，此功能仅适用于平台指标，自定义指标不支持此功能。

动态阈值警报规则还可以帮助一次为数百个指标系列（甚至不同类型）创建定制阈值，从而减少需要管理的警报规则。

本部分将介绍适用于三种方案的 Azure 资源管理器模板，它们用于使用单个规则监视多个资源。

  • 监视一个或多个资源组中的所有虚拟机（在单个 Azure 区域中）。
  • 监视单个订阅中的所有虚拟机（在单个 Azure 区域中）。
  • 监视单个订阅中的虚拟机列表（在单个 Azure 区域中）。

注意

  • 在监视多个资源的指标警报规则中，仅允许包含一个条件。
  • 如果你要为单个资源创建指标警报，模板将使用目标资源的 ResourceId。 如果你要为多个资源创建指标警报，模板将使用目标资源的 scope、TargetResourceType 和 TargetResourceRegion。

一个或多个资源组中所有虚拟机上的静态阈值警报

此模板将创建静态阈值指标警报规则，用于监视一个或多个资源组中的所有虚拟机（在单个 Azure 区域中）的 CPU 百分比。

将下面的 json 保存为 all-vms-in-resource-group-static.json 以用于此演练。

具有指标警报的可用性测试

Application Insights 可用性测试可帮助监视全球各地的网站/应用程序的可用性。 当可用性测试在一定数量的位置失败时，可用性测试警报会通知你。 可用性测试会对与指标警报 (Microsoft.Insights/metricAlerts) 相同的资源类型发出警报。 以下示例将创建一个简单的可用性测试和相关警报。

注意

& 是 & 的 HTML 实体引用。 URL 参数仍由单个 & 分隔，但如果在 HTML 中提到 URL，则需要对其进行编码。 因此，如果 pingURL 参数值中包含“&”，则必须使用“&”对其进行转义。
