Functions

func CleanupAdapter

func CleanupAdapter(namespace, adapterDeploymentFile string)

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(namespace, adapterDeploymentFile string) error

CreateAdapter creates Custom Metrics - Stackdriver adapter adapterDeploymentFile should be a filename for adapter deployment located in StagingDeploymentLocation

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) *appsv1.Deployment

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

func SimpleStackdriverExporterDeployment

func SimpleStackdriverExporterDeployment(name, namespace string, replicas int32, metricValue int64) *appsv1.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) *appsv1.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) *v1.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.

type Metadata

type Metadata struct {
	Results []map[string]interface{}
}

Metadata has the information fetched from Stackdriver metadata API.

type Resource

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

Resource contains the resource type and labels from Stackdriver metadata API.
