The timestamp of the last change from passive to active is now tracked. This, with the timestamps of the last master_down and master_up events, allows detection of cases when MaxScale was failed over but the failover was not done. Currently, only a warning is logged if no new master has appeared within 90 seconds of a master_down event and MaxScale was set to active from passive. The last event and when the event was triggered is now shown for all servers. The latest change from passive to active is also shown.
