> Currently there are at least three issues with cache metrics:
> # When metrics are acquired on client, average put times are always zero. 
> This happens because timings are calculated on the client, but puts are 
> counted on servers.
> # Size and keySize are always zero even if cache is not empty.
> # Default metrics() method that doesn't take a cluster group provides metrics 
> for local node only. So if it's called on client, they are always empty. It 
> should calculate metrics for the whole cluster instead.
> Also looks like this code is very undertested. Coverage should be 
> significantly improved.
