Types

type CloudWatchEvents 

type CloudWatchEvents struct {
	*client.Client
}

Amazon CloudWatch Events helps you to respond to state changes in your AWS resources. When your resources change state they automatically send events into an event stream. You can create rules that match selected events in the stream and route them to targets to take action. You can also use rules to take action on a pre-determined schedule. For example, you can configure rules to: 

Automatically invoke an AWS Lambda function to update DNS entries when

an event notifies you that Amazon EC2 instance enters the running state. Direct specific API records from CloudTrail to an Amazon Kinesis stream for detailed analysis of potential security or availability risks. Periodically invoke a built-in target to create a snapshot of an Amazon EBS volume. For more information about Amazon CloudWatch Events features, see the Amazon CloudWatch Developer Guide (http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide). 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) *CloudWatchEvents

New creates a new instance of the CloudWatchEvents 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 CloudWatchEvents client from just a session.
svc := cloudwatchevents.New(mySession)

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

func (*CloudWatchEvents) DeleteRule 

func (c *CloudWatchEvents) DeleteRule(input *DeleteRuleInput) (*DeleteRuleOutput, error)

Deletes a rule. You must remove all targets from a rule using RemoveTargets before you can delete the rule. 

Note: When you delete a rule, incoming events might still continue to match

to the deleted rule. Please allow a short period of time for changes to take effect.

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/cloudwatchevents"
)

func main() {
	svc := cloudwatchevents.New(session.New())

	params := &cloudwatchevents.DeleteRuleInput{
		Name: aws.String("RuleName"), // Required
	}
	resp, err := svc.DeleteRule(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 (*CloudWatchEvents) DeleteRuleRequest 

func (c *CloudWatchEvents) DeleteRuleRequest(input *DeleteRuleInput) (req *request.Request, output *DeleteRuleOutput)

DeleteRuleRequest generates a "aws/request.Request" representing the client's request for the DeleteRule 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 DeleteRule 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 DeleteRuleRequest method.
req, resp := client.DeleteRuleRequest(params)

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

func (*CloudWatchEvents) DescribeRule 

func (c *CloudWatchEvents) DescribeRule(input *DescribeRuleInput) (*DescribeRuleOutput, error)

Describes the details of the specified rule.

Example 
package main

)

func main() {
	svc := cloudwatchevents.New(session.New())

	params := &cloudwatchevents.DescribeRuleInput{
		Name: aws.String("RuleName"), // Required
	}
	resp, err := svc.DescribeRule(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)

DescribeRuleRequest generates a "aws/request.Request" representing the client's request for the DescribeRule 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 DescribeRule 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 DescribeRuleRequest method.

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

func (*CloudWatchEvents) DisableRule 

func (c *CloudWatchEvents) DisableRule(input *DisableRuleInput) (*DisableRuleOutput, error)

Disables a rule. A disabled rule won't match any events, and won't self-trigger if it has a schedule expression. 

Note: When you disable a rule, incoming events might still continue to

match to the disabled rule. Please allow a short period of time for changes to take effect.

}

func (*CloudWatchEvents) EnableRule 

func (c *CloudWatchEvents) EnableRule(input *EnableRuleInput) (*EnableRuleOutput, error)

Enables a rule. If the rule does not exist, the operation fails. 

Note: When you enable a rule, incoming events might not immediately start

matching to a newly enabled rule. Please allow a short period of time for changes to take effect.

}

func (*CloudWatchEvents) PutRule 

func (c *CloudWatchEvents) PutRule(input *PutRuleInput) (*PutRuleOutput, error)

Creates or updates a rule. Rules are enabled by default, or based on value of the State parameter. You can disable a rule using DisableRule. 

Note: When you create or update a rule, incoming events might not immediately

start matching to new or updated rules. Please allow a short period of time for changes to take effect.

A rule must contain at least an EventPattern or ScheduleExpression. Rules with EventPatterns are triggered when a matching event is observed. Rules with ScheduleExpressions self-trigger based on the given schedule. A rule can have both an EventPattern and a ScheduleExpression, in which case the rule will trigger on matching events as well as on a schedule. 

Note: Most services in AWS treat : or / as the same character in Amazon

Resource Names (ARNs). However, CloudWatch Events uses an exact match in event patterns and rules. Be sure to use the correct ARN characters when creating event patterns so that they match the ARN syntax in the event you want to match.

Example 
package main

import (
	"fmt"

	"github.com/aws/aws-sdk-go/aws"

    fmt.Println(resp)
}

func (*CloudWatchEvents) PutTargets 

func (c *CloudWatchEvents) PutTargets(input *PutTargetsInput) (*PutTargetsOutput, error)

Adds target(s) to a rule. Targets are the resources that can be invoked when a rule is triggered. For example, AWS Lambda functions, Amazon Kinesis streams, and built-in targets. Updates the target(s) if they are already associated with the role. In other words, if there is already a target with the given target ID, then the target associated with that ID is updated.

In order to be able to make API calls against the resources you own, Amazon CloudWatch Events needs the appropriate permissions. For AWS Lambda and Amazon SNS resources, CloudWatch Events relies on resource-based policies. For Amazon Kinesis streams, CloudWatch Events relies on IAM roles. For more information, see Permissions for Sending Events to Targets (http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/EventsTargetPermissions.html) in the Amazon CloudWatch Developer Guide.

Input and InputPath are mutually-exclusive and optional parameters of a target. When a rule is triggered due to a matched event, if for a target: 

Neither Input nor InputPath is specified, then the entire event is passed

to the target in JSON form. InputPath is specified in the form of JSONPath (e.g. $.detail), then only the part of the event specified in the path is passed to the target (e.g. only the detail part of the event is passed). 

Input is specified in the form of a valid JSON, then the matched event

is overridden with this constant. Note: When you add targets to a rule, when the associated rule triggers, new or updated targets might not be immediately invoked. Please allow a short period of time for changes to take effect.

Output:

func (*CloudWatchEvents) TestEventPatternRequest 

func (c *CloudWatchEvents) TestEventPatternRequest(input *TestEventPatternInput) (req *request.Request, output *TestEventPatternOutput)

TestEventPatternRequest generates a "aws/request.Request" representing the client's request for the TestEventPattern 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 TestEventPattern 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 TestEventPatternRequest method.
req, resp := client.TestEventPatternRequest(params)

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

Targets are the resources that can be invoked when a rule is triggered. For example, AWS Lambda functions, Amazon Kinesis streams, and built-in targets.

Input and InputPath are mutually-exclusive and optional parameters of a target. When a rule is triggered due to a matched event, if for a target: 

Neither Input nor InputPath is specified, then the entire event is passed

to the target in JSON form. InputPath is specified in the form of JSONPath (e.g. $.detail), then only the part of the event specified in the path is passed to the target (e.g. only the detail part of the event is passed). 

Input is specified in the form of a valid JSON, then the matched event

is overridden with this constant.
