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 NewCPUCollector

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

NewCPUCollector returns a new Collector exposing kernel/system statistics.

func NewDiskstatsCollector

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

NewDiskstatsCollector returns a new Collector exposing disk device stats. Docs from https://www.kernel.org/doc/Documentation/iostats.txt

func NewFilesystemCollector

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

NewFilesystemCollector returns a new Collector exposing filesystems stats.

func NewLoadavgCollector

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

NewLoadavgCollector returns a new Collector exposing load average stats.

func NewMeminfoCollector

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

NewMeminfoCollector returns a new Collector exposing memory stats.

func NewNetDevCollector

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

NewNetDevCollector returns a new Collector exposing network device stats.

func NewNetStatCollector

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

NewNetStatCollector takes and returns a new Collector exposing network stats.

func NewSockStatCollector

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

NewSockStatCollector returns a new Collector exposing socket stats.

func NewStatCollector

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

NewStatCollector returns a new Collector exposing kernel/system statistics.

type NodeCollector

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

NodeCollector implements the prometheus.Collector interface.

func NewNodeCollector

func NewNodeCollector(logger log.Logger, filters ...string) (*NodeCollector, error)

NewNodeCollector creates a new NodeCollector.

func (NodeCollector) Collect

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

Collect implements the prometheus.Collector interface.

func (NodeCollector) Describe

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

Describe implements the prometheus.Collector interface.
