Functions

func BaseContainerLabels

func BaseContainerLabels(container *info.ContainerInfo) map[string]string

BaseContainerLabels implements ContainerLabelsFunc. It only exports the container name, first alias, and image name.

func DefaultContainerLabels

func DefaultContainerLabels(container *info.ContainerInfo) map[string]string

DefaultContainerLabels implements ContainerLabelsFunc. It exports the container name, first alias, image name as well as all its env and label values.

Types

type ContainerLabelsFunc

type ContainerLabelsFunc func(*info.ContainerInfo) map[string]string

ContainerLabelsFunc defines all base labels and their values attached to each metric exported by cAdvisor.

type PrometheusCollector

type PrometheusCollector struct {
	// contains filtered or unexported fields
}

PrometheusCollector implements prometheus.Collector.

func NewPrometheusCollector

func NewPrometheusCollector(i infoProvider, f ContainerLabelsFunc, includedMetrics container.MetricSet) *PrometheusCollector

NewPrometheusCollector returns a new PrometheusCollector. The passed ContainerLabelsFunc specifies which base labels will be attached to all exported metrics. If left to nil, the DefaultContainerLabels function will be used instead.

func (*PrometheusCollector) Collect

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

Collect fetches the stats from all containers and delivers them as Prometheus metrics. It implements prometheus.PrometheusCollector.

func (*PrometheusCollector) Describe

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

Describe describes all the metrics ever exported by cadvisor. It implements prometheus.PrometheusCollector.
