When upgrading to Database Visibility 4.4, you may encounter issues monitoring SQL Server where the database collector fails after a period of time.

In addition, on all database platforms, you may encounter the following issues related to database agent and Controller communication that affect the Live View, Object Browser, and Explain Plan screens:

  • Data displayed in the Controller is intermittent
  • Timeout issues on the Object Browser

Affected Software

This affects all Database agents versions 4.4.0-4.4.3 for all database platforms.


Downgrade to Database agent version, which is our latest stable build. Use this version until the updated 4.4.x version is available.


The issues described in the summary are addressed in Database Visibility 4.5 and 4.4.4.
