      Description

      Hi,

      I had some node restarts and so we can see cluster size was changing
      appropriately:

      https://18.220.168.208/graph/dashboard/db/pxc-galera-cluster-overview?orgId=1&from=1521936275384&to=1521939574076

      However if I zoom out to about last 24 hours it looks like Cluster did NOT
      ave any times it operated in reduced size

      https://18.220.168.208/graph/dashboard/db/pxc-galera-cluster-overview?orgId=1&from=1521908120097&to=1521991518319

      The problem is we're not using min_over_time to match the selected
      $interval as such if the time when node left cluster was short it could not
      be picked up with gauge "sampling" which happens.
