---------------------------------------
Summary: In visorcmd "cache on nodes" statistics mixes together
primary and backup entries
Key: IGNITE-6422
URL: https://issues.apache.org/jira/browse/IGNITE-6422
Project: Ignite
Issue Type: Bug
Components: visor
Affects Versions: 2.3
Reporter: Ilya Kasnacheev
Assignee: Vasiliy Sisko
Suppose we have a cache, with 1000 entries, one backup and eviction after 500
entries. Then, off-heap entries are doubled in visorcmd, while on-heap entries
are not:
{code}

| Nodes | 2 |
| Total size Min/Avg/Max | 1500 / 1500.00 / 1500 |
| Heap size Min/Avg/Max | 500 / 500.00 / 500 |
| Off-heap size Min/Avg/Max | 1000 / 1000.00 / 1000 |

'Hi' - Number of cache hits.

By contrast, on 1.9 it looks like this:
{code}
Cache 'EmployeesCache(@c0)':

NB: It might be feasible to keep number of backup entries displayed in
visorcmd, but without adding them up with primary entries. Another dedicated
line perhaps? Should also probably be consistent with other memory kinds.
