Functions

func GetEsHost 

func GetEsHost() string

Returns

func GetEsPort 

func GetEsPort() string

func New 

func New(beatName string, cfg *common.Config, topologyExpire int) (outputs.Outputer, error)

New instantiates a new output plugin instance publishing to elasticsearch.

Types

type Client 

type Client struct {
	Connection
	// contains filtered or unexported fields
}

func GetTestingElasticsearch 

func GetTestingElasticsearch() *Client

func NewClient 

func NewClient(
	s ClientSettings,
	onConnectCallback connectCallback,
) (*Client, error)

func NewConnectedClient 

func NewConnectedClient(cfg *common.Config) (*Client, error)

NewConnectedClient creates a new Elasticsearch client based on the given config. It uses the NewElasticsearchClients to create a list of clients then returns the first from the list that successfully connects.

func NewElasticsearchClients 

func NewElasticsearchClients(cfg *common.Config) ([]Client, error)

NewElasticsearchClients returns a list of Elasticsearch clients based on the given configuration. It accepts the same configuration parameters as the output, except for the output specific configuration options (index, pipeline, template) .If multiple hosts are defined in the configuration, a client is returned for each of them.

func (*Client) CheckTemplate 

func (client *Client) CheckTemplate(templateName string) bool

CheckTemplate checks if a given template already exist. It returns true if and only if Elasticsearch returns with HTTP status code 200.

func (*Client) Clone 

func (client *Client) Clone() *Client

func (*Client) LoadJSON 

func (client *Client) LoadJSON(path string, json map[string]interface{}) ([]byte, error)

func (*Client) LoadTemplate 

func (client *Client) LoadTemplate(templateName string, template map[string]interface{}) error

LoadTemplate loads a template into Elasticsearch overwriting the existing template if it exists. If you wish to not overwrite an existing template then use CheckTemplate prior to calling this method.

func (*Client) PublishEvent 

func (client *Client) PublishEvent(data outputs.Data) error

func (*Client) PublishEvents 

func (client *Client) PublishEvents(
	data []outputs.Data,
) ([]outputs.Data, error)

PublishEvents sends all events to elasticsearch. On error a slice with all events not published or confirmed to be processed by elasticsearch will be returned. The input slice backing memory will be reused by return the value.
