/**
* Allows to manage custom metrics.
*
* Note: Names of custom metric registries are required to start with 'custom.' (lower case) and may have additional
* dot-separated qualifiers. The prefix 'custoncustom' is automatically added if missed. For example, if provided custom registry name
* is "a.b.c.mname", it is automatically extended to "custom.a.b.c.mname".
*
* Any custom name or dot-separated name part can't have any spaces and must not be empty.
*
* Examples of custom metric registry names: "custom.admin", "custom.admin.sessions", "custom.processes", etc.
