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