[Rostislav Svoboda (Jira)]

    [ https://issues.jboss.org/browse/WFLY-11394?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13664685#comment-13664685 ] 

Rostislav Svoboda commented on WFLY-11394:
------------------------------------------

When I ask for JSON I get milliseconds, this is weird.

{code}
curl http://localhost:9990/metrics/base/jvm.uptime -H "Accept: application/json" && echo " vs." && curl http://localhost:9990/metrics/base/jvm.uptime
{  "jvm.uptime" : 2504965}
 vs.
# HELP base:jvm_uptime_seconds Displays the start time of the Java virtual machine in milliseconds. This attribute displays the approximate time when the Java virtual machine started.
# TYPE base:jvm_uptime_seconds gauge
base:jvm_uptime_seconds 2504.986
{code}
