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.

Property Value

Type	Description
List<AlarmOverride>	A set of overrides that control evaluations of the alarm. Each override can specify values for query, severity, body, and pending duration. When an alarm contains overrides, the Monitoring service evaluates each override in order, beginning with the first override in the array (index position `0`), and then evaluates the alarm's base values (`ruleName` value of `BASE`).

PendingDuration

Declaration

[JsonProperty(PropertyName = "pendingDuration")]
public string PendingDuration { get; set; }

Property Value

Type Description

Type	Description
string	The period of time that the condition defined in the alarm must persist before the alarm state changes from "OK" to "FIRING". 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". 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". The alarm updates its status to "OK" when the breaching condition has been clear for the most recent minute. Example: PT5M

string

The period of time that the condition defined in the alarm must persist before the alarm state changes from "OK" to "FIRING". 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".
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".
The alarm updates its status to "OK" when the breaching condition has been clear for the most recent minute.
Example: PT5M

Query

Declaration

[Required(ErrorMessage = "Query is required.")]
[JsonProperty(PropertyName = "query")]
public string Query { get; set; }

Property Value

Type Description

Type	Description
string	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 depend on the specified time range. More interval values are supported for smaller time ranges. You can optionally specify dimensions and grouping functions. Also, you can customize the absence detection period. Supported grouping functions: `grouping()`, `groupBy()`. For information about writing MQL expressions, see Editing the MQL Expression for a Query. For details about 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() ----- Example of absence alarm with custom absence detection period of 20 hours: ----- `CpuUtilization[1m]{availabilityDomain=\"cumS:PHX-AD-1\"}.absent(20h)`
