Vendor metrics - subsystem - statistics-enabled to get valid data
I was playing with vendor metrics and I received a lot of zeros.
Note: I use -Djboss.socket.binding.port-offset=100
So I started to wonder why and it's because of statistics are not enabled.
When I enabled statistics for Undertow and hit the WF server main page I saw some changes in metrics.
Later I realized this scenario is also mentioned in analysis, section WildFly Metrics with undefined value / statistic-enabled = false
So this is mainly tracking + discussion point now.
