-> NOTE: Each resource supports the creation of one of the following three levels.

escalations_critical

The escalations_critical supports the following:

  • comparison_operator - (Optional) Critical level alarm comparison operator. Default value: >. Valid values: >, >=, <, <=, !=, ==, GreaterThanYesterday, LessThanYesterday, GreaterThanLastWeek, LessThanLastWeek, GreaterThanLastPeriod, LessThanLastPeriod. NOTE: From version 1.231.0, comparison_operator can be set to ==.
  • statistics - (Optional) Critical level alarm statistics method. It must be consistent with that defined for metrics. For more information, see How to use it.
  • threshold - (Optional) Critical level alarm threshold value, which must be a numeric value currently.
  • times - (Optional, Int) Critical level alarm retry times. Default value: 3.

escalations_info

The escalations_info supports the following:

  • comparison_operator - (Optional) Info level alarm comparison operator. Default value: >. Valid values: >, >=, <, <=, !=, ==, GreaterThanYesterday, LessThanYesterday, GreaterThanLastWeek, LessThanLastWeek, GreaterThanLastPeriod, LessThanLastPeriod. NOTE: From version 1.231.0, comparison_operator can be set to ==.
  • statistics - (Optional) Info level alarm statistics method. It must be consistent with that defined for metrics. For more information, see How to use it.
  • threshold - (Optional) Info level alarm threshold value, which must be a numeric value currently.
  • times - (Optional, Int) Info level alarm retry times. Default value: 3.

escalations_warn

The escalations_warn supports the following:

  • comparison_operator - (Optional) Warn level alarm comparison operator. Default value: >. Valid values: >, >=, <, <=, !=, ==, GreaterThanYesterday, LessThanYesterday, GreaterThanLastWeek, LessThanLastWeek, GreaterThanLastPeriod, LessThanLastPeriod. NOTE: From version 1.231.0, comparison_operator can be set to ==.

  • threshold - (Optional) Warn level alarm threshold value, which must be a numeric value currently.
  • times - (Optional, Int) Warn level alarm retry times. Default value: 3.

prometheus

The prometheus supports the following:

  • prom_ql - (Optional) The PromQL query statement. Note: The data obtained by using the PromQL query statement is the monitoring data. You must include the alert threshold in this statement.
  • level - (Optional) The level of the alert. Valid values: Critical, Warn, Info.
  • times - (Optional, Int) The number of consecutive triggers. If the number of times that the metric values meet the trigger conditions reaches the value of this parameter, CloudMonitor sends alert notifications.

targets

The targets supports the following:

  • target_id - (Optional) The ID of the resource for which alerts are triggered. This is typically used to specify individual resources that should respond to the alert.
  • json_params - (Optional) Specifies additional parameters for the alert callback in JSON format. This can include configuration settings specific to the alert action.
  • level - (Optional) The level of the alert. Valid values: Critical, Warn, Info.
  • arn - (Optional) ARN uniquely identifies the resource that the alert targets. -> NOTE: The targets attribute is used to specify where notifications or actions should be directed when an alarm condition is met. This attribute corresponds to what is referred to as the "Push Channel" in the Alibaba Cloud console. -> NOTE: Currently, the Alibaba Cloud Resource Name (ARN) of the resource. To use, please submit an application.

composite_expression

The composite_expression supports the following:

  • level - (Optional) The level of the alert. Valid values: CRITICAL, WARN, INFO.
  • times - (Optional, Int) The number of consecutive triggers.
  • expression_raw - (Optional) The trigger conditions that are created by using expressions.
  • expression_list_join - (Optional) The relationship between the trigger conditions for multiple metrics. Valid values: &&, ||.
  • expression_list - (Optional, Set) The trigger conditions that are created in standard mode. See expression_list below.

composite_expression-expression_list

The expression_list supports the following:

  • metric_name - (Optional) The metric that is used to monitor the cloud service.
  • comparison_operator - (Optional) The operator that is used to compare the metric value with the threshold. Valid values: >, >=, <, <=, !=, ==, GreaterThanYesterday, LessThanYesterday, GreaterThanLastWeek, LessThanLastWeek, GreaterThanLastPeriod, LessThanLastPeriod. NOTE: From version 1.231.0, comparison_operator can be set to ==.
  • statistics - (Optional) The statistical method of the metric.
  • threshold - (Optional) The alert threshold.
  • period - (Optional) The aggregation period of the metric. Unit: seconds.

Attributes Reference

The following attributes are exported:

  • id - The resource ID in terraform of Alarm.
  • status - The status of the Alarm.

-> NOTE: Available since v1.163.0.

The timeouts block allows you to specify timeouts for certain actions:
