Esta página é uma coleção de consultas de exemplo do Azure Resource Graph para o Azure Monitor.

Azure Monitor

Exibir alertas recentes do Azure Monitor

Esta consulta de exemplo obtém todos os alertas do Azure Monitor que foram disparados nas últimas 12 horas e extrai propriedades comumente usadas.

alertsmanagementresources
| where properties.essentials.startDateTime > ago(12h)
| project
  alertId = id,
  name,
  monitorCondition = tostring(properties.essentials.monitorCondition),
  severity = tostring(properties.essentials.severity),
  monitorService = tostring(properties.essentials.monitorService),
  alertState = tostring(properties.essentials.alertState),
  targetResourceType = tostring(properties.essentials.targetResourceType),
  targetResource = tostring(properties.essentials.targetResource),
  subscriptionId,
  startDateTime = todatetime(properties.essentials.startDateTime),
  lastModifiedDateTime = todatetime(properties.essentials.lastModifiedDateTime),
  dimensions = properties.context.context.condition.allOf[0].dimensions, properties

az graph query -q "alertsmanagementresources | where properties.essentials.startDateTime > ago(12h) | project   alertId = id,   name,   monitorCondition = tostring(properties.essentials.monitorCondition),   severity = tostring(properties.essentials.severity),   monitorService = tostring(properties.essentials.monitorService),   alertState = tostring(properties.essentials.alertState),   targetResourceType = tostring(properties.essentials.targetResourceType),   targetResource = tostring(properties.essentials.targetResource),   subscriptionId,   startDateTime = todatetime(properties.essentials.startDateTime),   lastModifiedDateTime = todatetime(properties.essentials.lastModifiedDateTime),   dimensions = properties.context.context.condition.allOf[0].dimensions, properties"

Exibir alertas recentes do Azure Monitor enriquecidos com tags de recursos

Esta consulta de exemplo obtém todos os alertas do Azure Monitor que foram disparados nas últimas 12 horas, extrai propriedades comumente usadas e adiciona as tags do recurso de destino.

alertsmanagementresources
| where properties.essentials.startDateTime > ago(12h)
| where tostring(properties.essentials.monitorService) <> "ActivityLog Administrative"
| project // converting extracted fields to string / datetime to allow grouping
  alertId = id,
  name,
  monitorCondition = tostring(properties.essentials.monitorCondition),
  severity = tostring(properties.essentials.severity),
  monitorService = tostring(properties.essentials.monitorService),
  alertState = tostring(properties.essentials.alertState),
  targetResourceType = tostring(properties.essentials.targetResourceType),
  targetResource = tostring(properties.essentials.targetResource),
  subscriptionId,
  startDateTime = todatetime(properties.essentials.startDateTime),
  lastModifiedDateTime = todatetime(properties.essentials.lastModifiedDateTime),
  dimensions = properties.context.context.condition.allOf[0].dimensions, // usefor metric alerts and log search alerts
  properties
| extend targetResource = tolower(targetResource)
| join kind=leftouter
  ( resources | project targetResource = tolower(id), targetResourceTags = tags) on targetResource
