Alexey Kuznetsov commented on IGNITE-6846:
------------------------------------------
[~vkulichenko] times calculated the same way, by the same method on both client
and server.How it works : we start invoke by sending certain request to primary
node and waiting for response.When response is received we must calculate time,
but response message contains no information about whether it was 'read-only'
or 'update' operation. As a result we cannot decide whether we should increment
'read-only' or 'update' metric.
Solution can be add flag to message.

> {{CacheMetrics}} object has multiple metrics for various cache operations
> like {{get}}, {{put}} and {{remove}}, but nothing for
> {{invoke}}/{{EntryProcessor}}. It makes sense to add such metrics, for
> example:
> * Total number of `invoke` operations executed.
> * Number of `invoke` operations that included updates.
> * Number of read-only `invoke` operations.
> * Min/max/avg execution time.
> * ...
