Package com.wavefront.agent

Class QueuedAgentService

java.lang.Object

com.wavefront.agent.QueuedAgentService

All Implemented Interfaces:

ForceQueueEnabledProxyAPI, WavefrontV2API, com.wavefront.api.ProxyV2API, com.wavefront.api.SourceTagAPI

public class QueuedAgentService
extends Object
implements ForceQueueEnabledProxyAPI

A wrapper for any WavefrontAPI that queues up any result posting if the backend is not available. Current data will always be submitted right away (thus prioritizing live data) while background threads will submit backlogged data.
