> h3. Motivation
> It will be useful to have builtin metric source with jvm memory usage stats.
> h3. Definition of Done
> It must expose the following metrics as a separate gauge metric each:
>  * heap memory usage (init/used/commited/max)
>  * non-heap memory usage (init/used/commited/max)
>  * name of metrics should have the general prefix "jvm." to group all future jvm metrics together
> Also, it needs to check, if calculation of these stats is heavy and we need to cache it for some time windows.
