QAN API error: qh.Profile: No query classes for selected instance and time range.


Thanks for a really nice application!

I'm using pmm 1.0.5 docker image, and 3 percona-xtradb-cluster-5.6 nodes with latest pmm client for ubuntu 14.04.

The 3 nodes are seen in qan, but I've always this error popup:

QAN API error: "qh.Profile: No query classes for selected instance and time range. Please check whether your MySQL settings match the recommended.".
Check the /var/log/qan-api.log file in docker container for more information.

Here is the percona-server version:
5.6.32-78.1-56-log Percona XtraDB Cluster (GPL), Release rel78.1, Revision 979409a, WSREP version 25.17, wsrep_25.17
So, what are the "recommended MySQL settings" for having some analytics ?
