Subsystem metrics are missing from microprofile-metrics JSON output ------------------------------------------------------------------- Key: WFLY-12543 URL: https://issues.jboss.org/browse/WFLY-12543 Project: WildFly Issue Type: Bug Components: MP Metrics Affects Versions: 17.0.1.Final, 18.0.0.Beta1 Reporter: Richard DiCroce Assignee: Jeff Mesnil Priority: Major Fix For: 18.0.0.Final Calling /metrics with Accept = application/json results in much fewer metrics being returned than when it is called without Accept (and thus returns data in the OpenMetrics format). Specifically, all the subsystem metrics (anything affected by the prefix configured in the microprofile-metrics subsystem) are missing.
