Variables

var (

	// ErrNoData indicates the collector found no data to collect, but had no other error.
	ErrNoData = errors.New("collector returned no data")
)

Functions

func IsNoDataError

func IsNoDataError(err error) bool

IsNoDataError returns true if error is no data error.

func RegisterVariableLabels

func RegisterVariableLabels(storeLabel bool, whiteListed string, enhanceMetrics bool)

RegisterVariableLabels sets storeLabels or whiteListed labels to be converted to metrics.

func SetPodmanCollectorState

func SetPodmanCollectorState(name string, state bool)

SetPodmanCollectorState enable/disable collectors.

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 NewContainerStatsCollector

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

NewContainerStatsCollector returns a Collector exposing containers stats information.

func NewImageStatsCollector

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

NewImageStatsCollector returns a Collector exposing image stats information.

func NewNetworkStatsCollector

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

NewNetworkStatsCollector returns a Collector exposing network stats information.

func NewPodStatsCollector

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

NewPodStatsCollector returns a Collector exposing pod stats information.

func NewSystemCollector

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

NewSystemCollector returns a Collector exposing podman system information.

func NewVolumeStatsCollector

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

NewVolumeStatsCollector returns a Collector exposing volume stats information.

type PodmanCollector

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

PodmanCollector implements the prometheus.Collector interface.

func NewPodmanCollector

func NewPodmanCollector(logger log.Logger) (*PodmanCollector, error)

NewPodmanCollector creates a new PodmanCollector.

func (PodmanCollector) Collect

func (p PodmanCollector) Collect(ch chan<- prometheus.Metric)

Collect implements the prometheus.Collector interface.

func (PodmanCollector) Describe

func (p PodmanCollector) Describe(ch chan<- *prometheus.Desc)

Describe implements the prometheus.Collector interface.
