             Summary: Fix Undertow Metrics
                 Key: WFLY-11256
                 URL: https://issues.jboss.org/browse/WFLY-11256
             Project: WildFly
          Issue Type: Bug
          Components: Web (Undertow)
    Affects Versions: 14.0.0.Final
            Reporter: Jeff Mesnil
            Assignee: Jeff Mesnil


Undertow metrics are relevant only when /subsystem=undertow's statistics-enabled is true.

When that it not the case (and metrics can not be computer) 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.
