create

Description

Creates a new alarm in the specified compartment.

Usage

oci monitoring alarm create [OPTIONS]

Required Parameters

--compartment-id, -c [text]

The OCID of the compartment containing the alarm.

--destinations [complex type]

A list of destinations for alarm notifications. Each destination is represented by the OCID of a related resource, such as a topic. Supported destination services: Notifications, Streaming. Limit: One destination per supported destination service. This is a complex type whose value must be valid JSON. The value can be provided as a string on the command line or passed in as a file using the file://path/to/file syntax.

The --generate-param-json-input option can be used to generate an example of the JSON which must be provided. We recommend storing this example in a file, modifying it as needed and then passing it back in via the file:// syntax.

--display-name [text]

A user-friendly name for the alarm. It does not have to be unique, and it’s changeable. Avoid entering confidential information.

This value determines the title of each alarm notification.

Example:

High CPU Utilization
--is-enabled [boolean]

Whether the alarm is enabled.

Example:

true
--metric-compartment-id [text]

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

--namespace [text]

The source service or application emitting the metric that is evaluated by the alarm.

Example:

oci_computeagent
--query-text [text]

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()

--severity [text]

The perceived type of response required when the alarm is in the “FIRING” state.

Example:

CRITICAL

Optional Parameters

--alarm-summary [text]

Customizable alarm summary (alarmSummary alarm message parameter). Optionally include dynamic variables. The alarm summary appears within the body of the alarm message and in responses to ListAlarmStatus GetAlarmHistory and RetrieveDimensionStates.

--body [text]

The human-readable content of the delivered alarm notification. Optionally include dynamic variables. 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.
--defined-tags [complex type]

Usage of predefined tag keys. These predefined keys are scoped to namespaces. Example: {“Operations”: {“CostCenter”: “42”}} This is a complex type whose value must be valid JSON. The value can be provided as a string on the command line or passed in as a file using the file://path/to/file syntax.

The --generate-param-json-input option can be used to generate an example of the JSON which must be provided. We recommend storing this example in a file, modifying it as needed and then passing it back in via the file:// syntax.

--evaluation-slack-duration [text]

Customizable slack period to wait for metric ingestion before evaluating the alarm. Specify a string in ISO 8601 format (PT10M for ten minutes or PT1H for one hour). Minimum: PT3M. Maximum: PT2H. Default: PT3M. For more information about the slack period, see About the Internal Reset Period.

--freeform-tags [complex type]

Simple key-value pair that is applied without any predefined name, type or scope. Exists for cross-compatibility only. Example: {“Department”: “Finance”} This is a complex type whose value must be valid JSON. The value can be provided as a string on the command line or passed in as a file using the file://path/to/file syntax.

The --generate-param-json-input option can be used to generate an example of the JSON which must be provided. We recommend storing this example in a file, modifying it as needed and then passing it back in via the file:// syntax.

--from-json [text]

Provide input to this command as a JSON document from a file using the file://path-to/file syntax.

The --generate-full-command-json-input option can be used to generate a sample json file to be used with this command option. The key names are pre-populated and match the command option names (converted to camelCase format, e.g. compartment-id –> compartmentId), while the values of the keys need to be populated by the user before using the sample file as an input to this command. For any command option that accepts multiple values, the value of the key can be a JSON array.

Options can still be provided on the command line. If an option exists in both the JSON document and the command line then the command line specified value will be used.

For examples on usage of this option, please see our “using CLI with advanced JSON options” link: https://docs.cloud.oracle.com/iaas/Content/API/SDKDocs/cliusing.htm#AdvancedJSONOptions

--is-notifications-per-metric-dimension-enabled [boolean]

When set to true, splits alarm notifications per metric stream. When set to false, groups alarm notifications across metric streams. Example: true

--max-wait-seconds [integer]

The maximum time to wait for the resource to reach the lifecycle state defined by --wait-for-state. Defaults to 1200 seconds.

--message-format [text]

The format to use for alarm notifications. The formats are: * RAW - Raw JSON blob. Default value. When the destinations attribute specifies Streaming, all alarm notifications use this format. * PRETTY_JSON: JSON with new lines and indents. Available when the destinations attribute specifies Notifications only. * ONS_OPTIMIZED: Simplified, user-friendly layout. Available when the destinations attribute specifies Notifications only. Applies to Email subscription types only.

Accepted values are:

ONS_OPTIMIZED, PRETTY_JSON, RAW
--metric-compartment-id-in-subtree [boolean]

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
--notification-title [text]

Customizable notification title (title alarm message parameter). Optionally include dynamic variables. The notification title appears as the subject line in a formatted email message and as the title in a Slack message.

--notification-version [text]

The version of the alarm notification to be delivered. Allowed value: 1.X The value must start with a number (up to four digits), followed by a period and an uppercase X.

--overrides [complex type]

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).

This option is a JSON list with items of type AlarmOverride. For documentation on AlarmOverride please see our API reference: https://docs.cloud.oracle.com/api/#/en/monitoring/20180401/datatypes/AlarmOverride. This is a complex type whose value must be valid JSON. The value can be provided as a string on the command line or passed in as a file using the file://path/to/file syntax.

The --generate-param-json-input option can be used to generate an example of the JSON which must be provided. We recommend storing this example in a file, modifying it as needed and then passing it back in via the file:// syntax.

--pending-duration [text]

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
--repeat-notification-duration [text]

The frequency for re-submitting alarm notifications, 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 [text]

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

--resource-group [text]

Resource group that you want to match. A null value returns only metric data that has no resource groups. The alarm retrieves metric data associated with the specified resource group only. 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
--rule-name [text]

Identifier of the alarm’s base values for alarm evaluation, for use when the alarm contains overrides. Default value is BASE. For information about alarm overrides, see AlarmOverride.

--suppression [complex type]

The configuration details for suppressing an alarm. This is a complex type whose value must be valid JSON. The value can be provided as a string on the command line or passed in as a file using the file://path/to/file syntax.

The --generate-param-json-input option can be used to generate an example of the JSON which must be provided. We recommend storing this example in a file, modifying it as needed and then passing it back in via the file:// syntax.

--wait-for-state [text]

This operation creates, modifies or deletes a resource that has a defined lifecycle state. Specify this option to perform the action and then wait until the resource reaches a given lifecycle state. Multiple states can be specified, returning on the first state. For example, --wait-for-state SUCCEEDED --wait-for-state FAILED would return on whichever lifecycle state is reached first. If timeout is reached, a return code of 2 is returned. For any other error, a return code of 1 is returned.

Accepted values are:

ACTIVE, DELETED, DELETING
--wait-interval-seconds [integer]

Check every --wait-interval-seconds to see whether the resource has reached the lifecycle state defined by --wait-for-state. Defaults to 30 seconds.

Example using required parameter

Copy and paste the following example into a JSON file, replacing the example parameters with your own.

    oci monitoring alarm create --generate-param-json-input destinations > destinations.json

Copy the following CLI commands into a file named example.sh. Run the command by typing “bash example.sh” and replacing the example parameters with your own.

Please note this sample will only work in the POSIX-compliant bash-like shell. You need to set up the OCI configuration and appropriate security policies before trying the examples.
