Functions ¶

func BaseContainerLabels ¶

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

BaseContainerLabels returns a ContainerLabelsFunc that exports the container name, first alias, image name as well as all its white listed env and label values.

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, now clock.Clock, opts v2.RequestOptions) *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.

type PrometheusMachineCollector ¶

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

PrometheusMachineCollector implements prometheus.Collector.

func NewPrometheusMachineCollector ¶

func NewPrometheusMachineCollector(i infoProvider, includedMetrics container.MetricSet) *PrometheusMachineCollector

NewPrometheusMachineCollector returns a new PrometheusCollector.

func (*PrometheusMachineCollector) Collect ¶

func (collector *PrometheusMachineCollector) Collect(ch chan<- prometheus.Metric)

Collect fetches information about machine and delivers them as Prometheus metrics. It implements prometheus.PrometheusCollector.

func (*PrometheusMachineCollector) Describe ¶

func (collector *PrometheusMachineCollector) Describe(ch chan<- *prometheus.Desc)

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