v5.8.0

Release date

29th August 2025

important

In 5.7.0 we 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.

Note that PostgreSQL 15 will not work with Redhat Enterprise Linux 7 or other Linux distros based on RHEL 7 like CentOS, Oracle Linux 7, Amazon Linux 2.

Improvements​

  • We added a new DB Versions screen showing the versions of databases you are monitoring, their end of support and end of life dates, and the latest patch or cumulative update you could upgrade to.
  • Multiple DBmarlin Co-pilot improvements:
    • AI Co-pilot now saves the Provider or Model only when clicking the Save button.
    • You can now send Deadlock details to get advice on them.
    • Support added for the latest GPT-5 models from both OpenAI and OpenRouter.
  • SSL in the DBmarlin Nginx server is now supported. If you create an ssl.conf file, it will be pulled in via nginx.conf.
  • Multiple improvements to the upgrade process:
    • Reduced Data-Migrator time, making upgrades involving schema changes much faster.
    • Fixed a Deadlock that could sometimes occur when dropping old schema.
    • TimeScaleDB Continuous Aggregate jobs are now stopped during Data-Migrator.
  • Infrastructure updates for Tomcat, Java, and Nginx, including the latest security and bug fixes.

Fixes​

  • The support-files scripts for Windows and Linux have been updated to use the new PostgreSQL 15 log directory.
  • A friendlier error message is now displayed on Blocking Sessions when the selected period is too large.
  • Fixed an issue where the Hosts badge was not updating correctly.
  • Fixed an issue where the change & event history table was not displayed if there were only changes.
  • Fixed an issue where Blocking Sessions SQL text was not visible on hover and the table below the graphic was not updating.
  • Fixed an issue where the Activity Comparison report was missing the vertical bar between charts.

Known Issues​

  • Event markers are not displayed correctly on the activity graph compared to the Events page.
  • Object statistics for Oracle may contain only partial information, such as table names, but may be 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 that requires TLS v1.0 or v1.1 (now obsolete), you will need to edit ./lib/security/java.security to change disabledAlgorithms and restart DBmarlin Tomcat. See this FAQ for more details.
