Types ¶
type HeapsterMetricsClient ¶
type HeapsterMetricsClient struct {
// contains filtered or unexported fields
}
HeapsterMetricsClient is Heapster-based implementation of MetricsClient
func NewHeapsterMetricsClient ¶
func NewHeapsterMetricsClient(client clientset.Interface, namespace, scheme, service, port string) *HeapsterMetricsClient
NewHeapsterMetricsClient returns a new instance of Heapster-based implementation of MetricsClient interface.
func (*HeapsterMetricsClient) GetCPUUtilization ¶ added in v1.1.1
func (h *HeapsterMetricsClient) GetCPUUtilization(namespace string, selector labels.Selector) (*int, time.Time, error)
func (*HeapsterMetricsClient) GetCpuConsumptionAndRequestInMillis ¶ added in v1.2.0
func (h *HeapsterMetricsClient) GetCpuConsumptionAndRequestInMillis(namespace string, selector labels.Selector) (avgConsumption int64,
avgRequest int64, timestamp time.Time, err error)
func (*HeapsterMetricsClient) GetCustomMetric ¶ added in v1.2.0
func (h *HeapsterMetricsClient) GetCustomMetric(customMetricName string, namespace string, selector labels.Selector) (*float64, time.Time, error)
GetCustomMetric returns the average value of the given custom metric from the pods picked using the namespace and selector passed as arguments.
type MetricsClient ¶
type MetricsClient interface {
// GetCPUUtilization returns the average utilization over all pods represented as a percent of requested CPU
// (e.g. 70 means that an average pod uses 70% of the requested CPU)
// and the time of generation of the oldest of utilization reports for pods.
GetCPUUtilization(namespace string, selector labels.Selector) (*int, time.Time, error)
// GetCustomMetric returns the average value of the given custom metrics from the
// pods picked using the namespace and selector passed as arguments.
GetCustomMetric(customMetricName string, namespace string, selector labels.Selector) (*float64, time.Time, error)
}
MetricsClient is an interface for getting metrics for pods.
