Types

type CloudWatchConfig

type CloudWatchConfig interface {
	GetIsEnabled() bool
	Enable(engineConfiguration interface{}) error
	Disable() error
	ParseEngineConfiguration() (config string, err error)
	Update(log log.T) error
	Write() error
}

func Instance

func Instance() CloudWatchConfig

Instance returns a singleton of CloudWatchConfig instance

type CloudWatchConfigImpl

type CloudWatchConfigImpl struct {
	IsEnabled           bool        `json:"IsEnabled"`
	EngineConfiguration interface{} `json:"EngineConfiguration"`
}

CloudWatchConfigImpl represents the data structure of cloudwatch configuration singleton, which contains the essential information to configure cloudwatch plugin

func (*CloudWatchConfigImpl) Disable

func (cwcInstance *CloudWatchConfigImpl) Disable() error

Disable changes the IsEnabled property in cloud watch config from true to false

func (*CloudWatchConfigImpl) Enable

func (cwcInstance *CloudWatchConfigImpl) Enable(engineConfiguration interface{}) error

Enable changes the IsEnabled property in cloud watch config from false to true

func (*CloudWatchConfigImpl) GetIsEnabled

func (cwcInstance *CloudWatchConfigImpl) GetIsEnabled() bool

GetIsEnabled returns true if configuration is enabled. Otherwise, it returns false.

func (*CloudWatchConfigImpl) ParseEngineConfiguration

func (cwcInstance *CloudWatchConfigImpl) ParseEngineConfiguration() (config string, err error)

ParseEngineConfiguration marshals the EngineConfiguration from interface{} to string

func (*CloudWatchConfigImpl) Update

func (cwcInstance *CloudWatchConfigImpl) Update(log log.T) error

Update updates configuration from file system

func (*CloudWatchConfigImpl) Write

func (cwcInstance *CloudWatchConfigImpl) Write() error

Write writes the updated configuration of cloud watch to file system

type Ec2ConfigXmlParser

type Ec2ConfigXmlParser interface {
	IsCloudWatchEnabled() (bool, error)
}

Ec2ConfigXmlParser is an interface for Ec2Config's configuration xml parser

type Ec2ConfigXmlParserImpl
