Class NodeMetricsClient

java.lang.Object
ai.vespa.metricsproxy.http.application.NodeMetricsClient
public class NodeMetricsClient extends Object
Retrieves metrics from a single Vespa node over http. To avoid unnecessary load on metrics proxies, a cached snapshot per consumer is retained and served for a fixed TTL period. Upon failure to retrieve metrics, an empty snapshot is cached.

This class assumes that the consumer id is a valid and existing one, which is already ensured by the ApplicationMetricsHandler.
