My cluster recently experienced a problem where the 3 nodes in my cluster became unsynced. To catch this problem as soon as possible in the future, which WSREP status variables can I monitor to ensure the cluster nodes are in sync? Any other status variables to watch for general health you can recommend would also be appreciated.

Thank you.
