performance => InnoDB Status empty

Hi,

I got a galera cluster with 3 nodes.

I added it to cluster control. Everything works fine except tab performance.

Example:

performance => InnoDB Status is filled for node 1. But empty fore node 2 & 3. It says "No data". Did I missed somehting? 

EDIT:

In my debug log, I got this spamming :
