Creates or updates a composite alarm

Source: R/cloudwatch_operations.R
cloudwatch_put_composite_alarm.Rd

Creates or updates a composite alarm. When you create a composite alarm, you specify a rule expression for the alarm that takes into account the alarm states of other alarms that you have created. The composite alarm goes into ALARM state only if all conditions of the rule are met.

See https://www.paws-r-sdk.com/docs/cloudwatch_put_composite_alarm/ for full documentation.

Usage

cloudwatch_put_composite_alarm(
  ActionsEnabled = NULL,
  AlarmActions = NULL,
  AlarmDescription = NULL,
  AlarmName,
  AlarmRule,
  InsufficientDataActions = NULL,
  OKActions = NULL,
  Tags = NULL,
  ActionsSuppressor = NULL,
  ActionsSuppressorWaitPeriod = NULL,
  ActionsSuppressorExtensionPeriod = NULL
)

Arguments

ActionsEnabled

Indicates whether actions should be executed during any changes to the alarm state of the composite alarm. The default is TRUE.

AlarmActions

The actions to execute when this alarm transitions to the ALARM state from any other state. Each action is specified as an Amazon Resource Name (ARN).

Valid Values: ]

Amazon SNS actions:

arn:aws:sns:region:account-id:sns-topic-name

Lambda actions:

  • Invoke the latest version of a Lambda function: arn:aws:lambda:region:account-id:function:function-name

  • Invoke a specific version of a Lambda function: arn:aws:lambda:region:account-id:function:function-name:version-number

  • Invoke a function by using an alias Lambda function: arn:aws:lambda:region:account-id:function:function-name:alias-name

Systems Manager actions:

arn:aws:ssm:region:account-id:opsitem:severity

Start a Amazon Q Developer operational investigation

arn:aws:aiops:region:account-id:investigation-group:investigation-group-id

AlarmDescription

The description for the composite alarm.

AlarmName

[required] The name for the composite alarm. This name must be unique within the Region.

AlarmRule

[required] An expression that specifies which other alarms are to be evaluated to determine this composite alarm's state. For each alarm that you reference, you designate a function that specifies whether that alarm needs to be in ALARM state, OK state, or INSUFFICIENT_DATA state. You can use operators (AND, OR and NOT) to combine multiple functions in a single expression. You can use parenthesis to logically group the functions in your expression.

You can use either alarm names or ARNs to reference the other alarms that are to be evaluated.

Functions can include the following:

  • ALARM("alarm-name or alarm-ARN") is TRUE if the named alarm is in ALARM state.

  • OK("alarm-name or alarm-ARN") is TRUE if the named alarm is in OK state.

  • INSUFFICIENT_DATA("alarm-name or alarm-ARN") is TRUE if the named alarm is in INSUFFICIENT_DATA state.

  • TRUE always evaluates to TRUE.

  • FALSE always evaluates to FALSE.

TRUE and FALSE are useful for testing a complex AlarmRule structure, and for testing your alarm actions.

Alarm names specified in AlarmRule can be surrounded with double-quotes ("), but do not have to be.

The following are some examples of AlarmRule:

  • ALARM(CPUUtilizationTooHigh) AND ALARM(DiskReadOpsTooHigh) specifies that the composite alarm goes into ALARM state only if both CPUUtilizationTooHigh and DiskReadOpsTooHigh alarms are in ALARM state.

  • ALARM(CPUUtilizationTooHigh) AND NOT ALARM(DeploymentInProgress) specifies that the alarm goes to ALARM state if CPUUtilizationTooHigh is in ALARM state and DeploymentInProgress is not in ALARM state. This example reduces alarm noise during a known deployment window.

  • (ALARM(CPUUtilizationTooHigh) OR ALARM(DiskReadOpsTooHigh)) AND OK(NetworkOutTooHigh) goes into ALARM state if CPUUtilizationTooHigh OR DiskReadOpsTooHigh is in ALARM state, and if NetworkOutTooHigh is in OK state. This provides another example of using a composite alarm to prevent noise. This rule ensures that you are not notified with an alarm action on high CPU or disk usage if a known network problem is also occurring.

The AlarmRule can specify as many as 100 "children" alarms. The AlarmRule expression can have as many as 500 elements. Elements are child alarms, TRUE or FALSE statements, and parentheses.

InsufficientDataActions

The actions to execute when this alarm transitions to the INSUFFICIENT_DATA state from any other state. Each action is specified as an Amazon Resource Name (ARN).

Valid Values: ]

Amazon SNS actions:

arn:aws:sns:region:account-id:sns-topic-name

Lambda actions:

  • Invoke the latest version of a Lambda function: arn:aws:lambda:region:account-id:function:function-name

  • Invoke a specific version of a Lambda function: arn:aws:lambda:region:account-id:function:function-name:version-number

  • Invoke a function by using an alias Lambda function: arn:aws:lambda:region:account-id:function:function-name:alias-name

OKActions

The actions to execute when this alarm transitions to an OK state from any other state. Each action is specified as an Amazon Resource Name (ARN).

Valid Values: ]

Amazon SNS actions:

arn:aws:sns:region:account-id:sns-topic-name

Lambda actions:

  • Invoke the latest version of a Lambda function: arn:aws:lambda:region:account-id:function:function-name

  • Invoke a specific version of a Lambda function: arn:aws:lambda:region:account-id:function:function-name:version-number

  • Invoke a function by using an alias Lambda function: arn:aws:lambda:region:account-id:function:function-name:alias-name

Tags

A list of key-value pairs to associate with the alarm. You can associate as many as 50 tags with an alarm. To be able to associate tags with the alarm when you create the alarm, you must have the cloudwatch:TagResource permission.

Tags can help you organize and categorize your resources. You can also use them to scope user permissions by granting a user permission to access or change only resources with certain tag values.

If you are using this operation to update an existing alarm, any tags you specify in this parameter are ignored. To change the tags of an existing alarm, use tag_resource or untag_resource.

ActionsSuppressor

Actions will be suppressed if the suppressor alarm is in the ALARM state. ActionsSuppressor can be an AlarmName or an Amazon Resource Name (ARN) from an existing alarm.

ActionsSuppressorWaitPeriod

The maximum time in seconds that the composite alarm waits for the suppressor alarm to go into the ALARM state. After this time, the composite alarm performs its actions.

WaitPeriod is required only when ActionsSuppressor is specified.

ActionsSuppressorExtensionPeriod

The maximum time in seconds that the composite alarm waits after suppressor alarm goes out of the ALARM state. After this time, the composite alarm performs its actions.

ExtensionPeriod is required only when ActionsSuppressor is specified.
