Tableau Server Application Server

The Application Server (VizPortal) handles the web application and REST API calls. Application Server also supports browsing and searching. To ensure high availability of Application Server, configure instances on each node in the Tableau Server cluster.


Application Server

StatusStatus of the Application Server process is visible on the Status Page. For more information, see View Server Process Status
LoggingLogs generated by the Application Server process are located in C:\ProgramData\Tableau\Tableau Server\data\tabsvc\logs\vizportal. For more information, see Tableau Server Logs and Log File Locations

What happens when an Application Server process fails? Requests being handled by that instance will fail, but subsequent requests will be routed to other running Application Server processes. Assuming the node containing the failed Application Server is still running, the failed process should automatically restart within seconds.
