    v9 v10  
    353514. Adding statistics in existing code MUST be easy to do (preferably a single call without any complex getters, accessors and intermediate objects)
    363615. MUST be usable in hooks libraries.
    37 16. MUST be able to report combinations of existing metrics (e.g. pool_utilization = assigned / total). The supported operations are + (addition), - (subtraction), * (multiplication), /(division).
     3716. ~~MUST be able to report combinations of existing metrics (e.g. pool_utilization = assigned / total). The supported operations are + (addition), - (subtraction), * (multiplication), /(division).~~ (after discussion this capability was removed, it can be achieved by an external script, so it unnecessarily degrade performance).
    383817. MUST be possible to report or pool for a given statistic or statistics periodically, even when there's no incoming traffic. Either pooling (i.e. external trigger requests a statistic) or reporting (i.e. the server does timing on its own and reports periodically) is need, not both.
