Functions

func GetCloudFoundryRedisBindings

func GetCloudFoundryRedisBindings() (addrs, passwords, aliases []string)

Types

type Exporter

type Exporter struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

Exporter implements the prometheus.Exporter interface, and exports Redis metrics.

func NewRedisExporter

func NewRedisExporter(host RedisHost, namespace, checkSingleKeys, checkKeys string) (*Exporter, error)

NewRedisExporter returns a new exporter of Redis metrics. note to self: next time we add an argument, instead add a RedisExporter struct

func (*Exporter) Collect

func (e *Exporter) Collect(ch chan<- prometheus.Metric)

Collect fetches new metrics from the RedisHost and updates the appropriate metrics.

func (*Exporter) Describe

func (e *Exporter) Describe(ch chan<- *prometheus.Desc)

Describe outputs Redis metric descriptions.

func (*Exporter) SetScript

func (e *Exporter) SetScript(script []byte)

SetScript sets the Lua Redis script to be used.

type RedisHost

type RedisHost struct {
	Addrs     []string
	Passwords []string
	Aliases   []string
