Issue

After upgrading Tableau Server, the Data Engine may report frequent up and down alerts. The Data Engine is not going down when the alerts are reported.

Environment

Tableau Server 9.0 & 9.1

Resolution

Upgrade to Tableau Server 9.0.8, 9.1.2 or a later version. For more information, see Upgrading Tableau Server
 

Cause

The cluster controller component is attempting to make a connection to the Data Engine component every 6 seconds. If successful, it counts as a passed sample and if it cannot connect it is considered as unsuccessful.
