I have installed PMM and added hosts/databases. I have an xtradb-cluster I would like to monitor to determine if the nodes in the cluster are in sync but am not sure what metric to use or if it is even available. At the basic level I guess using 'show status like ‘wsrep\_cluster\_status%’ \<\> ‘Primary’ would work for each node. This feels clumsy, is there a better way to handle this?

Hi Mike,

We are using metric mysql\_global\_status\_wsrep\_local\_state in dashboards for getting node statuses.  
So it would be _mysql\_global\_status\_wsrep\_local\_state \< 4_

I want to create an alert that fires/emails when this happens. ( _mysql\_global\_status\_wsrep\_local\_state \< 4_) I am struggling to understand how to accomplish this. Thanks.
