* how the assessment is carried out in the checkCache method (clarification is
needed, since the calculated and actual figures differ from the theoretical
ones)

> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.2
> Reporter: Ilya Kasnacheev
> Assignee: Alexand Polyakov
> Priority: Minor
> Labels: iep-6
>
> They are currently not passed by ring and therefore only taken from current
> node, which returns incorrect (local) value.
> See CacheMetricsSnapshot class.
