Known Issues

  • Deleting a sensor will now complete asynchronously at the backend. It may still take several minutes before it completes if you have a lot of data. Please be patient and don't try to start/stop/edit the sensor while it is deleting. You may need to refresh the Settings screen in your browser to see the sensor disappear from the list. In a future release we will add better indication that a sensor is deleting.
  • For earlier versions of SQL Server you may see Invalid column name 'MODIFIED_EXTENT_PAGE_COUNT' reported to DBmarlin tomcat log which can be ignored.
  • If you already setup DBmarlin Co-pilot you will need to clear and re-enter your OpenAI API key because it can't decode the previously applied API key.
  • If you are monitoring a server which requires TLS v1.0 or v1.1 which are now obsolete you will need to edit ./lib/security/ to change disabledAlgorithms and restart the DBmarlin Tomcat. See this FAQ for more details.
