Struct MetricsClient 

pub struct MetricsClient { /* private fields */ }

Kubernetes metrics client.

Implementations

impl MetricsClient

pub async fn new() -> Result<Self, MetricsError>

Create a new metrics client using the default kubeconfig.

pub async fn with_context(context: &str) -> Result<Self, MetricsError>

Create a new metrics client with a specific kubeconfig context.

pub async fn current_context() -> Result<String, MetricsError>

Get the current context name.

pub async fn list_contexts() -> Result<Vec<String>, MetricsError>

List available contexts.

pub async fn get_pod_resources( &self, namespace: Option<&str>, ) -> Result<Vec<PodResources>, MetricsError>

Get pod resource specifications from the cluster.

pub async fn get_pod_metrics( &self, namespace: Option<&str>, ) -> Result<Vec<PodMetrics>, MetricsError>

Get pod metrics from the metrics-server.

Note: This requires the metrics-server to be installed in the cluster. The metrics API is a custom resource, so we use a raw request.

pub async fn compare_usage( &self, namespace: Option<&str>, ) -> Result<Vec<ResourceComparison>, MetricsError>

Compare actual usage against requested resources.

pub async fn is_metrics_available(&self) -> bool

Check if metrics-server is available.
