Additional Information

Identify and fix failing alerts

Failing alerts are often caused by content changes on Tableau Server. Encourage users to recreate alerts if changes like the following occur:

  • A workbook, view, or data field is removed or renamed.
  • Database credentials embedded in workbooks expire.
  • Data Driven Alerts require embedded credentials for Live Connections, the use of OAuth isn’t currently supported with Alerts.
  • A data source becomes inaccessible.
