> Fix For: 0.13.0

>
>
> Each unique URL is resulting in a new metric and the JMX reporter is keeping
> it all in memory. This can lead to OOM exceptions and require a server
> restart.
> We need to revisit the metrics and consider whether every single URL needs a
> metric or whether we can configure the level of granularity.
> Unfortunately, metrics collection with the JMX reporter is enabled by default.
> This JIRA should change the default to not be disabled.
