func AddLimits ¶

func AddLimits(ctx context.Context, cfg *scout.Config, pod *corev1.Pod, containerMetrics *scout.ContainerMetrics) error

GetLimits generates resource limits for containers in a pod.

It accepts: - ctx: The context for the request - cfg: The scout config containing Kubernetes clientsets - pod: The pod specification - containerMetrics: A pointer to a ContainerMetrics struct to populate

It populates the containerMetrics.Limits field with a map of container names to resource limits (CPU, memory, storage) for each container in the pod.

It returns: - Any error that occurred while fetching resource limits

func GetPod ¶

func GetPod(podName string, pods []corev1.Pod) (corev1.Pod, error)

GetPod returns a pod object with the given name from a list of pods.

func GetPodMetrics ¶

func GetPodMetrics(ctx context.Context, cfg *scout.Config, pod corev1.Pod) (*metav1beta1.PodMetrics, error)

GetPodMetrics fetches metrics for a given pod from the Kubernetes Metrics API. It accepts: - ctx: The context for the request - cfg: The scout config containing Kubernetes clientsets - pod: The pod specification

It returns: - podMetrics: The PodMetrics object containing metrics for the pod - Any error that occurred while fetching the metrics

func GetPods ¶

func GetPods(ctx context.Context, cfg *scout.Config) ([]corev1.Pod, error)

GetPods fetches all pods in a given namespace.

func GetPvcCapacity ¶

func GetPvcCapacity(ctx context.Context, cfg *scout.Config, container corev1.Container, pod *corev1.Pod) (*resource.Quantity, error)

GetPvcCapacity returns the storage capacity of a PersistentVolumeClaim mounted to a container.

It accepts: - ctx: The context for the request - cfg: The scout config containing Kubernetes clientsets - container: The container specification - pod: The pod specification

It returns: - The storage capacity of the PVC in bytes - Any error that occurred while fetching the PVC

If no PVC is mounted to the container, nil is returned for the capacity and no error.

func GetRawUsage ¶

func GetRawUsage(usages corev1.ResourceList, targetKey string) (float64, error)

GetRawUsage returns the raw usage value for a given resource type from a Kubernetes ResourceList.

It accepts: - usages: A Kubernetes ResourceList containing usage values - targetKey: The resource type to get the usage for (e.g. "cpu" or "memory")

It returns: - The raw usage value for the target resource type - Any error that occurred while parsing the usage value

func GetStorageUsage ¶

func GetStorageUsage(
	ctx context.Context,
	cfg *scout.Config,
	podName string,
	containerName string,
) (float64, float64, error)

GetStorageUsage returns the storage capacity and usage for a given pod and container.

It accepts: - ctx: The context for the request - cfg: The scout config containing Kubernetes clientsets - podName: The name of the pod - containerName: The name of the container

It returns: - storageCapacity: The total storage capacity for the container in bytes - storageUsage: The used storage for the container in bytes - Any error that occurred while fetching the storage usage

func GetUsage ¶

func GetUsage(
	ctx context.Context,
	cfg *scout.Config,
	metrics scout.ContainerMetrics,
	pod corev1.Pod,
	container metav1beta1.ContainerMetrics,
) (scout.UsageStats, error)

GetUsage generates resource usage statistics for a Kubernetes container.

It accepts: - ctx: The context for the request - cfg: The scout config containing Kubernetes clientsets - metrics: Container resource limits - pod: The pod specification - container: Container metrics from the Metrics API

It returns: - usageStats: A UsageStats struct containing the resource usage info - Any error that occurred while generating the usage stats
