v5.7.0

Release date

30th July 2025

important

In this version we have moved to a later version of PostgreSQL for the DBmarlin repository database. During the upgrade process pg_upgrade is run so that the data files are converted to the newer format. If your original DBmarlin install was done starting at v1.5 (May 2021) or earlier, please contact support@applicationperformance.com before running this upgrade as you may require addition steps to complete the pg_upgrade.

Improvements​

  • We added a new Dashboard screen which lets you visualise your database estate in powerful new ways. The Dashboard supports three display modes for flexible viewing preferences: Compact, Comfortable, List views. Users can customise the view by grouping, sorting or filtering instances. Additionally, users can quickly drill down for detailed insights on a specific instance or group by clicking on their names. To return to the traditional instance view, from the dashboard select from the left-hand menu, or if viewing an instance from the dashboard then simply use the button (View Instance) located at the top right corner of the screen.
  • New Tag Settings screen allows you to set tags across multiple instances in one screen instead of setting them instance by instance.
  • We added support for Object Statistics collection for SQL Server and Oracle. This can be turned on under Advanced mode in the instance Settings. You can then use the Object Browser screen to view object details for tables, index and columns and their statistics.
  • Backend Upgrades: This release includes critical backend changes supporting the 5.2 schema upgrade, updates to metadata, and migrations to PostgreSQL 15 as well as TimescaleDB upgraded to version 2.20 for the DBmarlin repository.
  • The status icon on Dashboard, Instances Overview and Instance Dashboard now shows red if the sensor was unable to connect to the target database (previously it was grey). Mouseover on the icon shows the reason it could not connect.

Fixes​

  • Resolved some issues in the Object Browser for smoother navigation.
  • Fixed UI inconsistencies on the Blocking Sessions page to improve usability.
  • Addressed a bug affecting SQL Search functionality giving duplicate search results in some cases.

Known Issues​

  • Event markers are not displayed correctly on the activity graph compared to the Events page.
  • Object statistics for Oracle may only have partial information including table names but missing index and column names. This can be improved by increasing oracle.jdbc.ReadTimeout in Advanced Connection Settings for the sensor.
  • 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/java.security to change disabledAlgorithms and restart the DBmarlin Tomcat. See this FAQ for more details.
