Types

type Collector

type Collector interface {
	// Get new metrics and expose them via prometheus registry.
	Update(ch chan<- prometheus.Metric) error
}

Collector is the interface a collector has to implement.

func NewNFTablesCollector

func NewNFTablesCollector(logger log.Logger) (Collector, error)

NewNFTablesCollector returns a new Collector exposing IpTables stats.

type MainCollector

type MainCollector struct {
	Collectors map[string]Collector
	// contains filtered or unexported fields
}

MainCollector implements the prometheus.Collector interface.

func NewMainCollector

func NewMainCollector(logger log.Logger, filters ...string) (*MainCollector, error)

NewMainCollector creates a new MainCollector.

func (MainCollector) Collect

func (n MainCollector) Collect(ch chan<- prometheus.Metric)

Collect implements the prometheus.Collector interface.

func (MainCollector) Describe

func (n MainCollector) Describe(ch chan<- *prometheus.Desc)

Describe implements the prometheus.Collector interface.
