What errors are logged

Published Dashboards and Widgets can generate errors when viewed.
Typically, this will show a Data retrieval error message in place of the Widget’s visuals :

Data Retrieval Error message

This means that the Widget was unable to get the required data.

These errors can have several explanations :

  • data not available
  • SQL error
  • wrong query

When viewed from Alpana Designer or Preview, you can access the full error message, see the relevant help page.

When viewed from Alpana Server, you can access the full error message from the web interface, or inside a file, see below :
