v5.2.0

Release date

7th Mar 2025

Improvements​

  • On the Activity screen the Waits tab, each Wait event has a “Find out more” dropdown, which now includes links to “Knowledge Base” and “Send to DBmarlin Co-pilot” options.
  • Implemented a global search functionality for all instance lists, improving navigation and accessibility.
  • Improved legends in the “Top Waits” chart on the Activity Comparison page for enhanced clarity and readability.

Fixes​

  • Resolved known timezone-related issues affecting Database and Instance Activity tracking.
  • Addressed UI inconsistencies in the Database Statistics section.
  • Fixed multiple EXPLAIN errors in the PostgreSQL database, enhancing query performance and analysis.
  • Corrected instance filtering in reports to display only the relevant instances.
  • Fixed an issue in the Host Detail view where data did not refresh when switching hosts.

Known Issues​

  • 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.
  • Instance sorting in reports is incorrect and will be addressed in an upcoming update.
  • The statement table does not update correctly on Activity comparison reports; a fix is planned for version 5.3.
  • For CockroachDB Transaction Contention monitoring, it is possible that you could see a duplicate key warning the log file. This warning is related to aggregation of this data failing. The impact of this is that in the UI, you will only be able to see Transaction Contention data if the interval size is 1 hour or less (E.g. 5 mins, 15 mins). This would be the default when looking at a period of 1 day. For longer time ranges you will not be able to see data. This will be fixed in v5.4 of DBmarlin.
