C# (CSharp) Amazon.CloudWatch.Model Namespace

The AlarmHistoryItem data type contains descriptive information about the history of a specific alarm. If you call DescribeAlarmHistory, Amazon CloudWatch returns this data type as part of the DescribeAlarmHistoryResult data type.

The Datapoint data type encapsulates the statistical data that Amazon CloudWatch computes from metric data.

Retrieves history for the specified alarm. Filter alarms by date range or item type. If an alarm name is not specified, Amazon CloudWatch returns histories for all of the owner's alarms.

NOTE: Amazon CloudWatch retains the history of an alarm for two weeks, whether or not you delete the alarm.

Retrieves all alarms for a single metric. Specify a statistic, period, or unit to filter the set of alarms further.

The output for the DescribeAlarmsForMetric action.

The output for the DescribeAlarms action.

The Dimension data type further expands on the identity of a metric using a Name, Value pair.

For examples that use one or more dimensions, see PutMetricData.

Disables actions for the specified alarms. When an alarm's actions are disabled the alarm's state may change, but none of the alarm's actions will execute.

Up to 500 results are returned for any one call. To retrieve additional results, use the returned token with subsequent calls.

After you create a metric, allow up to fifteen minutes before the metric appears. Statistics about the metric, however, are available sooner using GetMetricStatistics.

The example in the Examples section publishes two metrics named buffers and latency. Both metrics are in the examples namespace. Both metrics have two dimensions, InstanceID and InstanceType.

The MetricAlarm data type represents an alarm. You can use PutMetricAlarm to create or update an alarm.

The MetricDatum data type encapsulates the information sent with PutMetricData to either create a new metric or add new values to be aggregated into an existing metric.

Creates or updates an alarm and associates it with the specified Amazon CloudWatch metric. Optionally, this operation can associate one or more Amazon Simple Notification Service resources with the alarm.

When this operation creates an alarm, the alarm state is immediately set to INSUFFICIENT_DATA . The alarm is evaluated and its StateValue is set appropriately. Any actions associated with the StateValue is then executed.

NOTE: When updating an existing alarm, its StateValue is left unchanged.

The size of a PutMetricData request is limited to 8 KB for HTTP GET requests and 40 KB for HTTP POST requests.

Data that is timestamped 24 hours or more in the past may take in excess of 48 hours to become available from submission time using GetMetricStatistics.

Temporarily sets the state of an alarm. When the updated StateValue differs from the previous value, the action configured for the appropriate state is invoked. This is not a permanent change. The next periodic alarm check (in about a minute) will set the alarm to its actual state.

The StatisticSet data type describes the StatisticValues component of MetricDatum, and represents a set of statistics that describes a specific metric.
