--------------------------------------

             Summary: mp.metrics.tags does not work when specified in MP config subsystem
                 Key: WFLY-12549
                 URL: https://issues.jboss.org/browse/WFLY-12549
             Project: WildFly
          Issue Type: Bug
          Components: MP Metrics
    Affects Versions: 18.0.0.Beta1
            Reporter: Richard DiCroce
            Assignee: Jeff Mesnil


Section 3.1.2 of the MP Metrics spec states:

{quote}
Tags can be supplied in two ways:
...
At the application server level by using MicroProfile Config and setting a configuration property of the name mp.metrics.tags.
{quote}

This does not work in WildFly if the property is configured inline in the Microprofile Config subsystem like this:
{code}
        <subsystem xmlns="urn:wildfly:microprofile-config-smallrye:1.0">
            <config-source name="props">
                <property name="mp.metrics.tags" value="foo=bar"/>
            </config-source>
        </subsystem>
{code}

Workaround: specify it under <system-properties> instead. This works as expected:

{code}
    <system-properties>
        <property name="mp.metrics.tags" value="foo=bar"/>
    </system-properties>
{code}
