Constants

const Type config.Type = "memcachedreceiver"

Type is the component type name.

Variables

var A = Attributes

A is an alias for Attributes.

var AttributeCommand = struct {
	Get   string
	Set   string
	Flush string
	Touch string
}{
	"get",
	"set",
	"flush",
	"touch",
}

AttributeCommand are the possible values that the attribute "command" can have.

var AttributeDirection = struct {
	Sent     string
	Received string
}{
	"sent",
	"received",
}

AttributeDirection are the possible values that the attribute "direction" can have.

var AttributeOperation = struct {
	Increment string
	Decrement string
	Get       string
}{
	"increment",
	"decrement",
	"get",
}

AttributeOperation are the possible values that the attribute "operation" can have.

var AttributeState = struct {
	System string
	User   string
}{
	"system",
	"user",
}

AttributeState are the possible values that the attribute "state" can have.

var AttributeType = struct {
	Hit  string
	Miss string
}{
	"hit",
	"miss",
}

AttributeType are the possible values that the attribute "type" can have.

var Attributes = struct {
	// Command (The type of command.)
	Command string
	// Direction (Direction of data flow.)
	Direction string
	// Operation (The type of operation.)
	Operation string
	// State (The type of CPU usage.)
	State string
	// Type (Result of cache request.)
	Type string
}{
	"command",
	"direction",
	"operation",
	"state",
	"type",
}

Attributes contains the possible metric attributes that can be used.
