Types

type AlarmHistoryItem 

type AlarmHistoryItem struct {
	// The descriptive name for the alarm.
	AlarmName *string `type:"string"`

	// Machine-readable data about the alarm in JSON format.
	HistoryData *string `type:"string"`

	// The type of alarm history item.
	HistoryItemType *string `type:"string"`

	// A human-readable summary of the alarm history.
	HistorySummary *string `type:"string"`

	// The time stamp for the alarm history item. Amazon CloudWatch uses Coordinated
	// Universal Time (UTC) when returning time stamps, which do not accommodate
	// seasonal adjustments such as daylight savings time. For more information,
	// see Time stamps (http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/cloudwatch_concepts.html#about_timestamp)
	// in the Amazon CloudWatch Developer Guide.
	Timestamp *time.Time `type:"timestamp" timestampFormat:"iso8601"`
	// contains filtered or unexported fields
}

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.

type CloudWatch 

type CloudWatch struct {
	*aws.Service
}

CloudWatch is a client for CloudWatch.

func New 

func New(config *aws.Config) *CloudWatch

New returns a new CloudWatch client.

func (*CloudWatch) DeleteAlarms 

func (c *CloudWatch) DeleteAlarms(input *DeleteAlarmsInput) (*DeleteAlarmsOutput, error)

Deletes all specified alarms. In the event of an error, no alarms are deleted.

Example 
package main

import (
	"fmt"

	"github.com/aws/aws-sdk-go/aws"
	"github.com/aws/aws-sdk-go/aws/awserr"
	"github.com/aws/aws-sdk-go/aws/awsutil"
	"github.com/aws/aws-sdk-go/service/cloudwatch"
)

func main() {
	svc := cloudwatch.New(nil)

	params := &cloudwatch.DeleteAlarmsInput{
		AlarmNames: []*string{ // Required
			aws.String("AlarmName"), // Required
			// More values...
		},
	}
	resp, err := svc.DeleteAlarms(params)

	if err != nil {
		if awsErr, ok := err.(awserr.Error); ok {
			// Generic AWS Error with Code, Message, and original error (if any)
			fmt.Println(awsErr.Code(), awsErr.Message(), awsErr.OrigErr())
			if reqErr, ok := err.(awserr.RequestFailure); ok {
				// A service error occurred
				fmt.Println(reqErr.Code(), reqErr.Message(), reqErr.StatusCode(), reqErr.RequestID())
			}
		} else {
			// This case should never be hit, the SDK should always return an
			// error which satisfies the awserr.Error interface.
			fmt.Println(err.Error())
		}
	}

	// Pretty-print the response data.
	fmt.Println(awsutil.StringValue(resp))
}

Output:

func (*CloudWatch) DeleteAlarmsRequest 

func (c *CloudWatch) DeleteAlarmsRequest(input *DeleteAlarmsInput) (req *aws.Request, output *DeleteAlarmsOutput)

}

Output:

func (*CloudWatch) EnableAlarmActionsRequest 

func (c *CloudWatch) EnableAlarmActionsRequest(input *EnableAlarmActionsInput) (req *aws.Request, output *EnableAlarmActionsOutput)

EnableAlarmActionsRequest generates a request for the EnableAlarmActions operation.

func (*CloudWatch) GetMetricStatistics 

func (c *CloudWatch) GetMetricStatistics(input *GetMetricStatisticsInput) (*GetMetricStatisticsOutput, error)

Gets statistics for the specified metric. 

The maximum number of data points returned from a single GetMetricStatistics

request is 1,440, wereas the maximum number of data points that can be queried is 50,850. If you make a request that generates more than 1,440 data points, Amazon CloudWatch returns an error. In such a case, you can alter the request by narrowing the specified time range or increasing the specified period. Alternatively, you can make multiple requests across adjacent time ranges. 

Amazon CloudWatch aggregates data points based on the length of the period

that you specify. For example, if you request statistics with a one-minute granularity, Amazon CloudWatch aggregates data points with time stamps that fall within the same one-minute period. In such a case, the data points queried can greatly outnumber the data points returned. 

The following examples show various statistics allowed by the data point

query maximum of 50,850 when you call GetMetricStatistics on Amazon EC2 instances with detailed (one-minute) monitoring enabled: 

Statistics for up to 400 instances for a span of one hour Statistics for

up to 35 instances over a span of 24 hours Statistics for up to 2 instances over a span of 2 weeks For information about the namespace, metric names, and dimensions that other Amazon Web Services products use to send metrics to Cloudwatch, go to Amazon CloudWatch Metrics, Namespaces, and Dimensions Reference (http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/CW_Support_For_AWS.html) in the Amazon CloudWatch Developer Guide.

Output:

func (*CloudWatch) GetMetricStatisticsRequest 

func (c *CloudWatch) GetMetricStatisticsRequest(input *GetMetricStatisticsInput) (req *aws.Request, output *GetMetricStatisticsOutput)

GetMetricStatisticsRequest generates a request for the GetMetricStatistics operation.

func (*CloudWatch) ListMetrics 

func (c *CloudWatch) ListMetrics(input *ListMetricsInput) (*ListMetricsOutput, error)

Returns a list of valid metrics stored for the AWS account owner. Returned metrics can be used with GetMetricStatistics to obtain statistical data for a given metric. 

Up to 500 results are returned for any one call. To retrieve further results,

use returned NextToken values with subsequent ListMetrics operations. If you create a metric with the PutMetricData action, allow up to fifteen minutes for the metric to appear in calls to the ListMetrics action. Statistics about the metric, however, are available sooner using GetMetricStatistics.

func (*CloudWatch) ListMetricsRequest 

func (c *CloudWatch) ListMetricsRequest(input *ListMetricsInput) (req *aws.Request, output *ListMetricsOutput)

ListMetricsRequest generates a request for the ListMetrics operation.

func (*CloudWatch) PutMetricAlarm 

func (c *CloudWatch) PutMetricAlarm(input *PutMetricAlarmInput) (*PutMetricAlarmOutput, error)

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. 

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

Output:

func (*CloudWatch) PutMetricAlarmRequest 

func (c *CloudWatch) PutMetricAlarmRequest(input *PutMetricAlarmInput) (req *aws.Request, output *PutMetricAlarmOutput)

PutMetricAlarmRequest generates a request for the PutMetricAlarm operation.

func (*CloudWatch) PutMetricData 

func (c *CloudWatch) PutMetricData(input *PutMetricDataInput) (*PutMetricDataOutput, error)

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. It can take up to fifteen minutes for a new metric to appear in calls to the ListMetrics action. 

The size of a PutMetricData request is limited to 8 KB for HTTP GET requests

and 40 KB for HTTP POST requests. 

Although the Value parameter accepts numbers of type Double, Amazon CloudWatch

truncates values with very large exponents. Values with base-10 exponents greater than 126 (1 x 10^126) are truncated. Likewise, values with base-10 exponents less than -130 (1 x 10^-130) are also truncated. 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.

Output:

func (*CloudWatch) PutMetricDataRequest 

func (c *CloudWatch) PutMetricDataRequest(input *PutMetricDataInput) (req *aws.Request, output *PutMetricDataOutput)

PutMetricDataRequest generates a request for the PutMetricData operation.

func (*CloudWatch) SetAlarmState 

func (c *CloudWatch) SetAlarmState(input *SetAlarmStateInput) (*SetAlarmStateOutput, error)

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.

Example 
package main
