Functions

func BasicAuth

func BasicAuth(username, password string) string

BasicAuth encode username and password to be used with basic authentication header

Types

type Alias

type Alias struct {
	// Index name.
	Index string
	// Alias name.
	Name string
	// IsWritedIndex option
	IsWriteIndex bool
}

Alias represents ES alias.

type Client

type Client struct {
	// Http client.
	Client *http.Client
	// ES server endpoint.
	Endpoint string
	// Basic authentication string.
	BasicAuth string
}

Client is a generic client to make requests to ES

type ClusterAPI

type ClusterAPI interface {
	Version() (uint, error)
}

type ClusterClient

type ClusterClient struct {
	Client
}

ClusterClient is a client used to get ES cluster information

func (*ClusterClient) Version

func (c *ClusterClient) Version() (uint, error)

Version returns the major version of the ES cluster

type ILMClient

type ILMClient struct {
	Client
	MasterTimeoutSeconds int
}

ILMClient is a client used to manipulate Index lifecycle management policies.

func (ILMClient) Exists

Exists verify if a ILM policy exists

type Index

type Index struct {
	// Index name.
	Index string
	// Index creation time.
	CreationTime time.Time
	// Aliases
	Aliases map[string]bool
}

Index represents ES index.

type IndexAPI

type IndexAPI interface {
	GetJaegerIndices(prefix string) ([]Index, error)
	DeleteIndices(indices []Index) error
	CreateIndex(index string) error

func (*IndicesClient) DeleteIndices

func (i *IndicesClient) DeleteIndices(indices []Index) error

DeleteIndices deletes specified set of indices.

func (*IndicesClient) GetJaegerIndices

func (i *IndicesClient) GetJaegerIndices(prefix string) ([]Index, error)

GetJaegerIndices queries all Jaeger indices including the archive and rollover. Jaeger daily indices are:

jaeger-span-2019-01-01, jaeger-service-2019-01-01, jaeger-dependencies-2019-01-01
jaeger-span-archive

Rollover indices:

aliases: jaeger-span-read, jaeger-span-write, jaeger-service-read, jaeger-service-write
    indices: jaeger-span-000001, jaeger-service-000001 etc.
aliases: jaeger-span-archive-read, jaeger-span-archive-write
    indices: jaeger-span-archive-000001

func (IndicesClient) Rollover

func (i IndicesClient) Rollover(rolloverTarget string, conditions map[string]interface{}) error

Rollover create a rollover for certain index/alias

type ResponseError

type ResponseError struct {
	// Error returned by the http client
	Err error
	// StatusCode is the http code returned by the server (if any)
	StatusCode int
	// Body is the bytes readed in the response (if any)
	Body []byte
}

ResponseError holds information about a request error

func (ResponseError) Error

func (r ResponseError) Error() string

Error returns the error string of the Err field
