Functions

func LogSize

func LogSize(reg prometheus.Registerer, next api.EntryHandler) api.EntryHandler

LogSize observes log line size for each stream.

Types

type CounterConfig

type CounterConfig struct {
	Value  *string `mapstructure:"value"`
	Action string  `mapstructure:"action"`
}

type Counters

type Counters struct {
	Cfg *CounterConfig
	// contains filtered or unexported fields
}

Counters is a vec tor of counters for a each log stream.

func NewCounters

func NewCounters(name, help string, config interface{}) (*Counters, error)

NewCounters creates a new counter vec.

func (Counters) Collect

func (c Counters) Collect(ch chan<- prometheus.Metric)

Collect implements prometheus.Collector

func (Counters) Describe

func (c Counters) Describe(ch chan<- *prometheus.Desc)

Describe implements prometheus.Collector and doesn't declare any metrics on purpose to bypass prometheus validation. see https://godoc.org/github.com/prometheus/client_golang/prometheus#hdr-Custom_Collectors_and_constant_Metrics search for "unchecked"

func (*Counters) With
