Is there a way to show the Cluster database's uptime?
Obviously I can see each individual node's database uptime with the likes of:
SHOW GLOBAL STATUS LIKE 'Uptime'; select TIME_FORMAT(SEC_TO_TIME(VARIABLE_VALUE ),"%Hh %im") as Uptime from information_schema.GLOBAL_STATUS where VARIABLE_NAME="Uptime";
But this is not the same as the time the cluster database has been operating without interruption...?
(and longest time of all the nodes would not necessarily give an approximation either as nodes can come and go, but the DB should still be up) (there doesn't see to be a suitable status variable, including wsrep variables)
