public void setEndpoint(String endpoint)
AmazonCloudWatch
Callers can pass in just the endpoint (ex: "monitoring.us-east-1.amazonaws.com") or a full URL, including the
protocol (ex: "https://monitoring.us-east-1.amazonaws.com"). If the protocol is not specified here, the default
protocol from this client's ClientConfiguration
will be used, which by default is HTTPS.
For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: http://developer.amazonwebservices.com/connect/entry.jspa?externalID=3912
This method is not threadsafe. An endpoint should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.

, sets the regional endpoint for this client's

By default, all service endpoints in all regions use the https protocol. To use http instead, specify it in the

public DeleteAlarmsResult deleteAlarms(DeleteAlarmsRequest request)
AmazonCloudWatch
Deletes the specified alarms. In the event of an error, no alarms are deleted.

public DescribeAlarmHistoryResult describeAlarmHistory(DescribeAlarmHistoryRequest request)
AmazonCloudWatch
Retrieves the history for the specified alarm. You can filter the results by date range or item type. If an alarm name is not specified, the histories for all alarms are returned.
Note that Amazon CloudWatch retains the history of an alarm even if you delete the alarm.

public DescribeAlarmsResult describeAlarms(DescribeAlarmsRequest request)
AmazonCloudWatch
Retrieves the specified alarms. If no alarms are specified, all alarms are returned. Alarms can be retrieved by using only a prefix for the alarm name, the alarm state, or a prefix for any action.

public DisableAlarmActionsResult disableAlarmActions(DisableAlarmActionsRequest request)
AmazonCloudWatch
Disables the actions for the specified alarms. When an alarm's actions are disabled, the alarm actions do not execute when the alarm state changes.

public GetMetricStatisticsResult getMetricStatistics(GetMetricStatisticsRequest request)
AmazonCloudWatch
Gets statistics for the specified metric.
Amazon CloudWatch retains metric data as follows:
Data points with a period of 60 seconds (1 minute) are available for 15 days
Data points with a period of 300 seconds (5 minute) are available for 63 days
Data points with a period of 3600 seconds (1 hour) are available for 455 days (15 months)
Note that CloudWatch started retaining 5-minute and 1-hour metric data as of 9 July 2016.
The maximum number of data points returned from a single call is 1,440. If you request more than 1,440 data points, Amazon CloudWatch returns an error. To reduce the number of data points, you can narrow the specified time range and make multiple requests across adjacent time ranges, or you can increase the specified period. A period can be as short as one minute (60 seconds). Note that data points are not returned in chronological order.
Amazon CloudWatch aggregates data points based on the length of the period that you specify. For example, if you request statistics with a one-hour period, Amazon CloudWatch aggregates all data points with time stamps that fall within each one-hour period. Therefore, the number of values aggregated by CloudWatch is larger than the number of data points returned.
CloudWatch needs raw data points to calculate percentile statistics. If you publish data using a statistic set instead, you cannot retrieve percentile statistics for this data unless one of the following conditions is true:
The SampleCount of the statistic set is 1
The Min and the Max of the statistic set are equal
For a list of metrics and dimensions supported by AWS services, see the Amazon CloudWatch Metrics and Dimensions Reference in the Amazon CloudWatch User Guide.
getMetricStatistics
in interface AmazonCloudWatch
public ListMetricsResult listMetrics(ListMetricsRequest request)
AmazonCloudWatch
List the specified metrics. You can use the returned metrics with GetMetricStatistics to obtain statistical data.
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.

AmazonCloudWatch.listMetrics(ListMetricsRequest)
public PutMetricAlarmResult putMetricAlarm(PutMetricAlarmRequest request)
AmazonCloudWatch
Creates or updates an alarm and associates it with the specified metric. Optionally, this operation can associate one or more Amazon SNS 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 state is set appropriately. Any actions associated with the state are then executed.
When you update an existing alarm, its state is left unchanged, but the update completely overwrites the previous configuration of the alarm.
If you are an AWS Identity and Access Management (IAM) user, you must have Amazon EC2 permissions for some operations:
ec2:DescribeInstanceStatus
and ec2:DescribeInstances
for all alarms on EC2 instance
status metrics
ec2:StopInstances
for alarms with stop actions
ec2:TerminateInstances
for alarms with terminate actions
ec2:DescribeInstanceRecoveryAttribute
and ec2:RecoverInstances
for alarms with recover
actions
If you have read/write permissions for Amazon CloudWatch but not for Amazon EC2, you can still create an alarm, but the stop or terminate actions won't be performed. However, if you are later granted the required permissions, the alarm actions that you created earlier will be performed.
If you are using an IAM role (for example, an Amazon EC2 instance profile), you cannot stop or terminate the instance using alarm actions. However, you can still see the alarm state and perform any other actions such as Amazon SNS notifications or Auto Scaling policies.
If you are using temporary security credentials granted using the AWS Security Token Service (AWS STS), you cannot stop or terminate an Amazon EC2 instance using alarm actions.
Note that you must create at least one stop, terminate, or reboot alarm using the Amazon EC2 or CloudWatch console to create the EC2ActionsAccess IAM role. After this IAM role is created, you can create stop, terminate, or reboot alarms using a command-line interface or an API.
putMetricAlarm
in interface AmazonCloudWatch
public PutMetricDataResult putMetricData(PutMetricDataRequest request)
AmazonCloudWatch
Publishes metric data points to Amazon CloudWatch. Amazon CloudWatch associates the data points with the specified metric. If the specified metric does not exist, Amazon CloudWatch creates the metric. When Amazon CloudWatch creates a metric, it can take up to fifteen minutes for the metric to appear in calls to ListMetrics.
Each PutMetricData
request is limited to 40 KB in size for HTTP POST requests.
Although the Value
parameter accepts numbers of type Double
, Amazon CloudWatch rejects
values that are either too small or too large. Values must be in the range of 8.515920e-109 to 1.174271e+108
(Base 10) or 2e-360 to 2e360 (Base 2). In addition, special values (e.g., NaN, +Infinity, -Infinity) are not
supported.
You can use up to 10 dimensions per metric to further clarify what data the metric collects. For more information on specifying dimensions, see Publishing Metrics in the Amazon CloudWatch User Guide.
Data points with time stamps from 24 hours ago or longer can take at least 48 hours to become available for GetMetricStatistics from the time they are submitted.
CloudWatch needs raw data points to calculate percentile statistics. If you publish data using a statistic set instead, you cannot retrieve percentile statistics for this data unless one of the following conditions is true:
The SampleCount of the statistic set is 1
The Min and the Max of the statistic set are equal
putMetricData
in interface AmazonCloudWatch
public SetAlarmStateResult setAlarmState(SetAlarmStateRequest request)
AmazonCloudWatch
Temporarily sets the state of an alarm for testing purposes. When the updated state differs from the previous
value, the action configured for the appropriate state is invoked. For example, if your alarm is configured to
send an Amazon SNS message when an alarm is triggered, temporarily changing the alarm state to ALARM
sends an Amazon SNS message. The alarm returns to its actual state (often within seconds). Because the alarm
state change happens very quickly, it is typically only visible in the alarm's History tab in the Amazon
CloudWatch console or through DescribeAlarmHistory.
