Types

type AlarmHistoryItem 

type AlarmHistoryItem struct {

	// The descriptive name for the alarm.
	AlarmName *string `min:"1" type:"string"`

	// Machine-readable data about the alarm in JSON format.
	HistoryData *string `min:"1" type:"string"`

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

	// A human-readable summary of the alarm history.
	HistorySummary *string `min:"1" type:"string"`

	// The time stamp for the alarm history item.
	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.

func (AlarmHistoryItem) GoString added in v0.6.5 

func (s AlarmHistoryItem) GoString() string

GoString returns the string representation

func (AlarmHistoryItem) String added in v0.6.5 

func (s AlarmHistoryItem) String() string

String returns the string representation

type CloudWatch 

type CloudWatch struct {
	*client.Client
}

Amazon CloudWatch monitors your Amazon Web Services (AWS) resources and the applications you run on AWS in real-time. You can use CloudWatch to collect and track metrics, which are the variables you want to measure for your resources and applications.

CloudWatch alarms send notifications or automatically make changes to the resources you are monitoring based on rules that you define. For example, you can monitor the CPU usage and disk reads and writes of your Amazon Elastic Compute Cloud (Amazon EC2) instances and then use this data to determine whether you should launch additional instances to handle increased load. You can also use this data to stop under-used instances to save money.

In addition to monitoring the built-in metrics that come with AWS, you can monitor your own custom metrics. With CloudWatch, you gain system-wide visibility into resource utilization, application performance, and operational health. The service client's operations are safe to be used concurrently. It is not safe to mutate any of the client's properties though.

func New 

func New(p client.ConfigProvider, cfgs ...*aws.Config) *CloudWatch

New creates a new instance of the CloudWatch client with a session. If additional configuration is needed for the client instance use the optional aws.Config parameter to add your extra config.

Example: 

// Create a CloudWatch client from just a session.
svc := cloudwatch.New(mySession)

// Create a CloudWatch client with additional configuration
svc := cloudwatch.New(mySession, aws.NewConfig().WithRegion("us-west-2"))

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

func main() {
	sess, err := session.NewSession()
	if err != nil {
		fmt.Println("failed to create session,", err)
		return
	}

	svc := cloudwatch.New(sess)

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

	if err != nil {
		// Print the error, cast err to awserr.Error to get the Code and
		// Message from an error.
		fmt.Println(err.Error())
		return
	}

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

Output:

func (*CloudWatch) DeleteAlarmsRequest 

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

DeleteAlarmsRequest generates a "aws/request.Request" representing the client's request for the DeleteAlarms operation. The "output" return value can be used to capture response data after the request's "Send" method is called.

Creating a request object using this method should be used when you want to inject custom logic into the request's lifecycle using a custom handler, or if you want to access properties on the request object before or after sending the request. If you just want the service response, call the DeleteAlarms method directly instead.

Note: You must call the "Send" method on the returned request object in order to execute the request. 

// Example sending a request using the DeleteAlarmsRequest method.
req, resp := client.DeleteAlarmsRequest(params)

err := req.Send()
if err == nil { // resp is now filled
    fmt.Println(resp)
}

func (*CloudWatch) DescribeAlarmHistory 

func (c *CloudWatch) DescribeAlarmHistory(input *DescribeAlarmHistoryInput) (*DescribeAlarmHistoryOutput, error)

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. 

Amazon CloudWatch retains the history of an alarm for two weeks, whether

or not you delete the alarm.

Example 
package main

import (
	"fmt"
	"time"

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

func main() {
	sess, err := session.NewSession()
	if err != nil {
		fmt.Println("failed to create session,", err)
		return
	}

	svc := cloudwatch.New(sess)

	params := &cloudwatch.DescribeAlarmHistoryInput{
		AlarmName:       aws.String("AlarmName"),
		EndDate:         aws.Time(time.Now()),
		HistoryItemType: aws.String("HistoryItemType"),
		MaxRecords:      aws.Int64(1),
		NextToken:       aws.String("NextToken"),
		StartDate:       aws.Time(time.Now()),
	}
	resp, err := svc.DescribeAlarmHistory(params)

	if err != nil {
		// Print the error, cast err to awserr.Error to get the Code and
		// Message from an error.
		fmt.Println(err.Error())
		return
	}

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

}

func (*CloudWatch) GetMetricStatistics 

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

Gets statistics for the specified metric. 

The maximum number of data points that can be queried is 50,850, whereas

the maximum number of data points returned from a single GetMetricStatistics request is 1,440. 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. A period can be as short as one minute (60 seconds) or as long as one day (86,400 seconds). Alternatively, you can make multiple requests across adjacent time ranges. GetMetricStatistics does not return the data 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-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

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.

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 PutMetricData, allow up to fifteen minutes

for the metric to appear in calls to ListMetrics. Statistics about the metric, however, are available sooner using GetMetricStatistics.

ListMetricsPages iterates over the pages of a ListMetrics operation, calling the "fn" function with the response data for each page. To stop iterating, return false from the fn function.

See ListMetrics method for more information on how to use this operation.

Note: This operation can generate multiple requests to a service. 

// Example iterating over at most 3 pages of a ListMetrics operation.
pageNum := 0
err := client.ListMetricsPages(params,
    func(page *ListMetricsOutput, lastPage bool) bool {
        pageNum++
        fmt.Println(page)
        return pageNum <= 3
    })

func (*CloudWatch) ListMetricsRequest 

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

ListMetricsRequest generates a "aws/request.Request" representing the client's request for the ListMetrics operation. The "output" return value can be used to capture response data after the request's "Send" method is called.

Creating a request object using this method should be used when you want to inject custom logic into the request's lifecycle using a custom handler, or if you want to access properties on the request object before or after sending the request. If you just want the service response, call the ListMetrics method directly instead.

Note: You must call the "Send" method on the returned request object in order to execute the request. 

// Example sending a request using the ListMetricsRequest method.
req, resp := client.ListMetricsRequest(params)

err := req.Send()
if err == nil { // resp is now filled
    fmt.Println(resp)
}

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 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 StateValue is set appropriately. Any actions associated with the StateValue are then executed. 

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

it completely overwrites the alarm's previous configuration. 

If you are using an AWS Identity and Access Management (IAM) account to

create or modify an alarm, you must have the following Amazon EC2 permissions: 

ec2:DescribeInstanceStatus and ec2:DescribeInstances for all alarms on

Amazon 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 on the Amazon EC2 instance. However, if you are later granted permission to use the associated Amazon EC2 APIs, the alarm actions you created earlier will be performed. For more information about IAM permissions, see Permissions and Policies (http://docs.aws.amazon.com/IAM/latest/UserGuide/PermissionsAndPolicies.html) in Using IAM.

If you are using an IAM role (e.g., 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.

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. 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 8 KB in size for HTTP GET requests

and 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. 

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.

func (*CloudWatch) SetAlarmState 

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

Temporarily sets the state of an alarm for testing purposes. When the updated StateValue 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's 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.
