» Argument Reference

The following arguments are supported:

» Attributes Reference

The following attributes are exported:

  • body - The human-readable content of the notification delivered. Oracle recommends providing guidance to operators for resolving the alarm condition. Consider adding links to standard runbook practices. Avoid entering confidential information. Example: High CPU usage alert. Follow runbook instructions for resolution.
  • compartment_id - The OCID of the compartment containing the alarm.
  • defined_tags - Usage of predefined tag keys. These predefined keys are scoped to namespaces. Example: {"Operations.CostCenter": "42"}
  • destinations - A list of destinations to which the notifications for this alarm will be delivered. Each destination is represented by an OCID related to the supported destination service. For example, a destination using the Notifications service is represented by a topic OCID. Supported destination services: Notifications Service. Limit: One destination per supported destination service.
  • display_name - A user-friendly name for the alarm. It does not have to be unique, and it's changeable. Avoid entering confidential information.

    This name is sent as the title for notifications related to this alarm.

    Example: High CPU Utilization

  • freeform_tags - Simple key-value pair that is applied without any predefined name, type or scope. Exists for cross-compatibility only. Example: {"Department": "Finance"}

  • id - The OCID of the alarm.

  • is_enabled - Whether the alarm is enabled. Example: true

  • metric_compartment_id - The OCID of the compartment containing the metric being evaluated by the alarm.

  • metric_compartment_id_in_subtree - When true, the alarm evaluates metrics from all compartments and subcompartments. The parameter can only be set to true when metricCompartmentId is the tenancy OCID (the tenancy is the root compartment). A true value requires the user to have tenancy-level permissions. If this requirement is not met, then the call is rejected. When false, the alarm evaluates metrics from only the compartment specified in metricCompartmentId. Default is false. Example: true

  • namespace - The source service or application emitting the metric that is evaluated by the alarm. Example: oci_computeagent

  • pending_duration - The period of time that the condition defined in the alarm must persist before the alarm state changes from "OK" to "FIRING" or vice versa. For example, a value of 5 minutes means that the alarm must persist in breaching the condition for five minutes before the alarm updates its state to "FIRING"; likewise, the alarm must persist in not breaching the condition for five minutes before the alarm updates its state to "OK."

    The duration is specified as a string in ISO 8601 format (PT10M for ten minutes or PT1H for one hour). Minimum: PT1M. Maximum: PT1H. Default: PT1M.

    Under the default value of PT1M, the first evaluation that breaches the alarm updates the state to "FIRING" and the first evaluation that does not breach the alarm updates the state to "OK".

    Example: PT5M

  • query - The Monitoring Query Language (MQL) expression to evaluate for the alarm. The Alarms feature of the Monitoring service interprets results for each returned time series as Boolean values, where zero represents false and a non-zero value represents true. A true value means that the trigger rule condition has been met. The query must specify a metric, statistic, interval, and trigger rule (threshold or absence). Supported values for interval: 1m-60m (also 1h). You can optionally specify dimensions and grouping functions. Supported grouping functions: grouping(), groupBy(). For details about Monitoring Query Language (MQL), see Monitoring Query Language (MQL) Reference. For available dimensions, review the metric definition for the supported service. See Supported Services.

    Example of threshold alarm:


    CpuUtilization[1m]{availabilityDomain="cumS:PHX-AD-1"}.groupBy(availabilityDomain).percentile(0.9) > 85


    Example of absence alarm:


    CpuUtilization[1m]{availabilityDomain="cumS:PHX-AD-1"}.absent()


  • repeat_notification_duration - The frequency at which notifications are re-submitted, if the alarm keeps firing without interruption. Format defined by ISO 8601. For example, PT4H indicates four hours. Minimum: PT1M. Maximum: P30D.

    Default value: null (notifications are not re-submitted).

    Example: PT2H

  • resolution - The time between calculated aggregation windows for the alarm. Supported value: 1m

  • resource_group - Resource group specified as a filter for metric data retrieved by the alarm. A resource group is a custom string that can be used as a filter. Only one resource group can be applied per metric. A valid resourceGroup value starts with an alphabetical character and includes only alphanumeric characters, periods (.), underscores (_), hyphens (-), and dollar signs ($). Avoid entering confidential information. Example: frontend-fleet

  • severity - The perceived type of response required when the alarm is in the "FIRING" state. Example: CRITICAL

  • state - The current lifecycle state of the alarm. Example: DELETED

  • suppression - The configuration details for suppressing an alarm.

    • description - Human-readable reason for suppressing alarm notifications. It does not have to be unique, and it's changeable. Avoid entering confidential information.

      Oracle recommends including tracking information for the event or associated work, such as a ticket number.

      Example: Planned outage due to change IT-1234.

    • time_suppress_from - The start date and time for the suppression to take place, inclusive. Format defined by RFC3339. Example: 2019-02-01T01:02:29.600Z

    • time_suppress_until - The end date and time for the suppression to take place, inclusive. Format defined by RFC3339. Example: 2019-02-01T02:02:29.600Z

  • time_created - The date and time the alarm was created. Format defined by RFC3339. Example: 2019-02-01T01:02:29.600Z

  • time_updated - The date and time the alarm was last updated. Format defined by RFC3339. Example: 2019-02-03T01:02:29.600Z
