How to monitor XtraDB Cluster by PMM 1.2.2

Dear all,

I have install PMM 1.2.2 and PXC 5.7.18. Cluster working well but i can’t monitor the PXC status in PMM.
However, PMM can monitor the mysql instance well. Any post-configuration need to make in order to monitor the PXC as well?

Regards,
Raymond
