Functions

func GetConfigForClientFunc

func GetConfigForClientFunc(certFile, keyFile, caCertFile string) func(*tls.ClientHelloInfo) (*tls.Config, error)

GetConfigForClientFunc returns a function for tls.Config.GetConfigForClient

func GetServerCertificateFunc

func GetServerCertificateFunc(certFile, keyFile string) func(*tls.ClientHelloInfo) (*tls.Certificate, error)

GetServerCertificateFunc returns a function for tls.Config.GetCertificate

func LoadCAFile

func LoadCAFile(caFile string) (*x509.CertPool, error)

LoadCAFile reads and parses CA certificates from a file into a pool. The file must contain PEM encoded data.

func LoadKeyPair

func LoadKeyPair(certFile, keyFile string) (*tls.Certificate, error)

LoadKeyPair reads and parses a public/private key pair from a pair of files. The files must contain PEM encoded data.

func LoadPwdFile

func LoadPwdFile(passwordFile string) (map[string]string, error)

LoadPwdFile reads the redis password file and returns the password map

Types

type BuildInfo

type BuildInfo struct {
	Version   string
	CommitSha string
	Date      string
}

type Exporter

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

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

func NewRedisExporter

func NewRedisExporter(redisURI string, opts Options) (*Exporter, error)

NewRedisExporter returns a new exporter of Redis metrics.

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) CreateClientTLSConfig

func (e *Exporter) CreateClientTLSConfig() (*tls.Config, error)

CreateClientTLSConfig verifies configured files and return a prepared tls.Config

func (*Exporter) CreateServerTLSConfig

func (e *Exporter) CreateServerTLSConfig(certFile, keyFile, caCertFile, minVersionString string) (*tls.Config, error)

CreateServerTLSConfig verifies configuration and return a prepared tls.Config

func (*Exporter) Describe

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

Describe outputs Redis metric descriptions.

func (*Exporter) ServeHTTP

func (e *Exporter) ServeHTTP(w http.ResponseWriter, r *http.Request)
