Helo everyone,

On version 5.6 of xtradb cluster graph is empty, but on percona server 5.5 everything is ok.
Is any soltution od that problem?

    Please check out if SHOW ENGINE INNODB STATUS reports the following line:

    Hash table size 4425293, used cells 4229064, ....

    If not, the graph will be empty.

    On Percona 5.6 "Hash table size" is absent in SHOW ENGINE INNODB STATUS

    I would say it's not necessary Percona 5.6, it depends. I have just checked Oracle MySQL 5.5 and it is also missed. "SHOW ENGINE INNODB STATUS" is not well-documented if at all, so that's not really clear under what circumstances "hash table size" is reported.
