用于 Azure Monitor 指标警报规则的资源管理器模板示例

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。

备注

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 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

备注

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

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 = Transactions,ResponseType = Server Timeout,ApiName = PutBlob

备注

使用动态阈值的指标警报规则目前不支持多个条件。
