Types

type CHTTPConfig

type CHTTPConfig struct {
	config.MonitorConfig
	// Where to find cAdvisor
	CAdvisorURL string `yaml:"cadvisorURL" default:"http://localhost:4194"`
}

CHTTPConfig is the monitor-specific config for cAdvisor

type Cadvisor

type Cadvisor struct {
	Monitor
	Output types.Output
}

Cadvisor is the monitor that goes straight to the exposed cAdvisor port to get metrics

func (*Cadvisor) Configure

func (c *Cadvisor) Configure(conf *CHTTPConfig) error

Configure the cAdvisor monitor

type KubeletStatsConfig

type KubeletStatsConfig struct {
	config.MonitorConfig
	// Kubelet client configuration
	KubeletAPI kubelet.APIConfig `yaml:"kubeletAPI" default:""`
}

KubeletStatsConfig respresents config for the Kubelet stats monitor

type KubeletStatsMonitor

type KubeletStatsMonitor struct {
	Monitor
	Output types.Output
}

KubeletStatsMonitor will pull container metrics from the /stats/ endpoint of the Kubelet API. This is the same thing that other K8s metric solutions like Heapster use and should eventually completely replace out use of the cAdvisor endpoint that some K8s deployments expose. Right now, this assumes a certain format of the stats that come off of the endpoints. TODO: Figure out if this is versioned and how to access versioned endpoints.

func (*KubeletStatsMonitor) Configure

func (ks *KubeletStatsMonitor) Configure(conf *KubeletStatsConfig) error

type Monitor

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

func (*Monitor) Shutdown
