Amostras de modelo do Resource Manager para regras de alerta de métrica no Azure Monitor

  • Artigo

Este artigo fornece exemplos de como usar os modelos do Azure Resource Manager para configurar regras de alerta de métrica no Azure Monitor. Cada amostra inclui um arquivo de modelo e um arquivo de parâmetros com valores de amostra para fornecer ao modelo.

Observação

Consulte Amostras do Azure Resource Manager do Azure Monitor para obter uma lista de amostras disponíveis e diretrizes sobre como implantá-las em sua assinatura do Azure.

Consulte Recursos com suporte para alertas de métrica no Azure Monitor para obter uma lista de recursos que podem ser usados com as regras de alerta de métrica. Uma explicação do esquema e das propriedades de uma regra de alerta está disponível em Alertas de métrica – Criar ou atualizar.

Observação

Modelo de recursos para criar alertas de métrica para o tipo de recurso: O espaço de trabalho do Azure Log Analytics (ou seja Microsoft.OperationalInsights/workspaces), requer etapas adicionais. Para obter detalhes, consulte Alerta de métrica para logs – Modelo de recursos.

Múltiplos critérios, limite estático

Os alertas de métrica dão suporte a alertas em métricas multidimensionais, bem como a até 5 critérios por regra de alerta. A amostra a seguir cria uma regra de alerta de métrica em métricas dimensionais e especifica vários critérios.

Ao usar dimensões em uma regra de alerta que contém vários critérios, as seguintes restrições se aplicam:

  • Só é possível selecionar um valor por dimensão dentro de cada critério.

  • Não é possível usar "*" como um valor de dimensão.

  • Quando as métricas configuradas em critérios diferentes dão suporte à mesma dimensão, um valor de dimensão configurado precisa ser definido explicitamente da mesma forma para todas essas métricas no critério relevante.

    • No exemplo a seguir, como as métricas Transactions e SuccessE2ELatency têm uma dimensão ApiName, e criterion1 especifica o valor "GetBlob" da dimensão ApiName, criterion2 precisará também configurar um valor "GetBlob" para a dimensão ApiName.

Múltiplas dimensões, limite estático

Uma regra de alerta pode monitorar várias séries temporais de métrica por vez, o que resulta em menos regras de alerta para gerenciar. A amostra a seguir cria uma regra de alerta de métrica estática em métricas dimensionais.

Nessa amostra, a regra de alerta monitora as combinações de valor das dimensões ResponseType e ApiName para a métrica Transactions:

  1. ResponsType – O uso do "*" curinga significa que, para cada valor da dimensão ResponseType, incluindo valores futuros, uma série temporal diferente é monitorada individualmente.
  2. ApiName – Uma série temporal diferente é monitorada apenas para os valores de dimensão GetBlob e PutBlob.

Por exemplo, algumas das séries temporais em potencial que são monitoradas por esta regra de alerta são:

  • 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

}

Observação

Usar "Todos" como um valor de dimensão é equivalente à seleção de "*" (todos os valores atuais e futuros).

Múltiplas dimensões, limites dinâmicos

Uma regra de alerta de limites dinâmicos pode criar limites sob medida para centenas de série temporais de métrica (até mesmo de diferentes tipos) de cada vez, o que resulta em menos regras de alerta para gerenciar. A amostra a seguir cria uma regra de alerta de métrica de limites dinâmicos em métricas dimensionais.

Nessa amostra, a regra de alerta monitora as combinações de valor das dimensões ResponseType e ApiName para a métrica Transactions:

  1. ResponsType – Para cada valor da dimensão ResponseType, incluindo valores futuros, uma série temporal diferente é monitorada individualmente.
  2. ApiName – Uma série temporal diferente é monitorada apenas para os valores de dimensão GetBlob e PutBlob.

Por exemplo, algumas das séries temporais em potencial que são monitoradas por esta regra de alerta são:

  • 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

Observação

No momento, não há suporte para múltiplos critérios para as regras de alerta de métrica que usam limites dinâmicos.

Métrica personalizada, limite estático

Você pode usar o modelo a seguir para criar uma regra de alerta de métrica de limite estático mais avançada em uma métrica personalizada.

Para saber mais sobre as métricas personalizadas no Azure Monitor, confira Métricas personalizadas no Azure Monitor.

Ao criar uma regra de alerta em uma métrica personalizada, você precisará especificar o nome da métrica e o namespace da métrica. Verifique também se a métrica personalizada já está sendo relatada, pois não é possível criar uma regra de alerta em uma métrica personalizada que ainda não existe.

Observação

Você pode encontrar o namespace de métrica de uma métrica personalizada específica pesquisando as suas métricas personalizadas por meio do portal do Azure

Recursos múltiplos

O Azure Monitor dá suporte ao monitoramento de múltiplos recursos do mesmo tipo com uma única regra de alerta de métrica para recursos que existem na mesma região do Azure. No momento, esse recurso tem suporte na nuvem pública do Azure e somente para máquinas virtuais, bancos de dados do SQL Server, pools elásticos do SQL Server e dispositivos do Azure Stack Edge. Além disso, esse recurso só está disponível para métricas de plataforma e não tem suporte para métricas personalizadas.

A regra de alerta de limites dinâmicos também pode ajudar a criar limites sob medida para centenas de série de métrica (até mesmo de diferentes tipos) de cada vez, o que resulta em menos regras de alerta a serem gerenciados.

Esta seção descreverá modelos do Azure Resource Manager para três cenários a fim de monitorar vários recursos com uma única regra.

  • Monitoramento de todas as máquinas virtuais (em uma única região do Azure) em um ou mais grupos de recursos.
  • Monitoramento de todas as máquinas virtuais (em uma região do Azure) em uma assinatura.
  • Monitoramento de uma lista de máquinas virtuais (em uma região do Azure) em uma assinatura.

Observação

  • Em uma regra de alerta de métrica que monitora vários recursos, apenas uma condição é permitida.
  • Se você estiver criando um alerta de métrica para um recurso individual, o modelo usará a ResourceId do recurso de destino. Se você estiver criando um alerta de métrica para vários recursos, o modelo usará o scope, o TargetResourceType e a TargetResourceRegion dos recursos de destino.

Alerta de limite estático em todas as máquinas virtuais em um ou mais grupos de recursos

Esse modelo criará uma regra de alerta de métrica de limite estático que monitora o percentual de CPU para todas as máquinas virtuais (em uma região do Azure) em um ou mais grupos de recursos.

Salve o json abaixo como all-vms-in-resource-group-static.json para usar neste passo a passo.

Teste de disponibilidade com o alerta de métrica

Os testes de disponibilidade do Application Insights ajudam você a monitorar a disponibilidade do seu site/aplicativo de vários locais em todo o mundo. Os alertas de teste de disponibilidade notificam você quando os testes de disponibilidade falham de um determinado número de locais. Os alertas de teste de disponibilidade do mesmo tipo de recurso que os alertas de métrica (Microsoft.Insights/metricAlerts). A amostra a seguir cria um teste de disponibilidade simples e um alerta associado.
