Functions ¶

func CheckCadvisorHealthOnAllNodes ¶

func CheckCadvisorHealthOnAllNodes(c clientset.Interface, timeout time.Duration)

func CleanupAdapter ¶

func CleanupAdapter() error

CleanupAdapter deletes Custom Metrics - Stackdriver adapter deployments.

func CleanupDescriptors ¶

func CleanupDescriptors(service *gcm.Service, projectId string)

CleanupDescriptors deletes descriptors for metrics: CustomMetricName and UnusedMetricName. TODO: Cleanup time series as well

func CreateAdapter ¶

func CreateAdapter() error

CreateAdapter creates Custom Metrics - Stackdriver adapter.

func CreateDescriptors ¶

func CreateDescriptors(service *gcm.Service, projectId string) error

CreateDescriptors creates descriptors for metrics: CustomMetricName and UnusedMetricName.

func PrometheusExporterDeployment ¶

func PrometheusExporterDeployment(name, namespace string, replicas int32, metricValue int64) *extensions.Deployment

PrometheusExporterDeployment is a Deployment of simple application with two containers one exposing a metric in prometheus fromat and second a prometheus-to-sd container that scrapes the metric and pushes it to stackdriver.

func Query ¶

func Query(c clientset.Interface, query string) (*influxdb.Response, error)

Query sends a command to the server and returns the Response

func SimpleStackdriverExporterDeployment ¶

func SimpleStackdriverExporterDeployment(name, namespace string, replicas int32, metricValue int64) *extensions.Deployment

SimpleStackdriverExporterDeployment is a Deployment of simple application that exports a metric of fixed value to Stackdriver in a loop.

func StackdriverExporterDeployment ¶

func StackdriverExporterDeployment(name, namespace string, replicas int32, containers []CustomMetricContainerSpec) *extensions.Deployment

StackdriverExporterDeployment is a Deployment of an application that can expose an arbitrary amount of metrics of fixed value to Stackdriver in a loop. Each metric is exposed by a different container in one pod. The metric names and values are configured via the containers parameter.

func StackdriverExporterPod ¶

func StackdriverExporterPod(podName, namespace, podLabel, metricName string, metricValue int64) *corev1.Pod

StackdriverExporterPod is a Pod of simple application that exports a metric of fixed value to Stackdriver in a loop.

Types ¶

type CustomMetricContainerSpec ¶

type CustomMetricContainerSpec struct {
	Name        string
	MetricName  string
	MetricValue int64
}

CustomMetricContainerSpec allows to specify a config for StackdriverExporterDeployment with multiple containers exporting different metrics.
