Fix Undertow Deployment Metrics ------------------------------- Key: WFLY-11335 URL: https://issues.jboss.org/browse/WFLY-11335 Project: WildFly Issue Type: Bug Components: Web (Undertow) Affects Versions: 14.0.0.Final Reporter: Jeff Mesnil Assignee: Jeff Mesnil Priority: Major Fix For: 15.0.0.Beta1, 15.0.0.Final Undertow deployment metrics are relevant only when /subsystem=undertow's statistics-enabled is true. When that it not the case (and metrics can not be computed) the metrics' read handler should not return a meaningless value (e.g. 0) as it already specifies an undefined metric value in the metrics' attribute definition. That change and WFCORE-4190 will prevent exposing Undertow metrics when they do not report actual metric from Undertow underlying runtime.
