--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Examples

To display information about alarms associated with a metric

The following example uses the describe-alarms-for-metric command to display information about any alarms associated with the Amazon EC2 CPUUtilization metric and the instance with the ID i-0c986c72.:

aws cloudwatch describe-alarms-for-metric --metric-name CPUUtilization --namespace AWS/EC2 --dimensions Name=InstanceId,Value=i-0c986c72

Output:

Output

The information for each alarm with the specified metric.

(structure)

Represents an alarm.

AlarmName -> (string)

The name of the alarm.

AlarmArn -> (string)

The Amazon Resource Name (ARN) of the alarm.

The time stamp of the last update to the alarm configuration.

ActionsEnabled -> (boolean)

Indicates whether actions should be executed during any changes to the alarm state.

(string)

AlarmActions -> (list)

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).

(string)

InsufficientDataActions -> (list)

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).

(string)

StateValue -> (string)

The state value for the alarm.

StateReason -> (string)

An explanation for the alarm state, in text format.

StateReasonData -> (string)

An explanation for the alarm state, in JSON format.

StateUpdatedTimestamp -> (timestamp)

The time stamp of the last update to the alarm state.

MetricName -> (string)

The name of the metric associated with the alarm.

Namespace -> (string)

The namespace of the metric associated with the alarm.

Statistic -> (string)

The statistic for the metric associated with the alarm, other than percentile. For percentile statistics, use extended-statistic .

ExtendedStatistic -> (string)

The percentile statistic for the metric associated with the alarm. Specify a value between p0.0 and p100.

Dimensions -> (list)

The dimensions for the metric associated with the alarm.

(structure)

Expands the identity of a metric.

Name -> (string)

The name of the dimension.

Value -> (string)

The value representing the dimension measurement.

Period -> (integer)

The period, in seconds, over which the statistic is applied.

Unit -> (string)

The unit of the metric associated with the alarm.

ComparisonOperator -> (string)

The arithmetic operation to use when comparing the specified statistic and threshold. The specified statistic value is used as the first operand.

TreatMissingData -> (string)

Sets how this alarm is to handle missing data points. If this parameter is omitted, the default behavior of missing is used.

EvaluateLowSampleCountPercentile -> (string)

Used only for alarms based on percentiles. If ignore , the alarm state does not change during periods with too few data points to be statistically significant. If evaluate or this parameter is not used, the alarm is always evaluated and possibly changes state no matter how many data points are available.
