  • The super_read_only variable is now represented in the Replication dashboard's instance drilldowns. The configured value is displayed in the Replication Configuration section.

Bugs Fixed

  • The Statement Type drop-down list on the Query Analyzer page contained incorrectly named entries, formatted as form.label.statementType.option.NAME. (Bug #26132066)

  • A Null Pointer Exception was logged if the Average Statement Execution Time advisor was enabled but all its notice thresholds were disabled. (Bug #25872561)

    The documentation was also updated with this information. (Bug #25697013)

  • Network speeds were incorrectly reported on the Network Interfaces table of the MySQL Instances dashboard. (Bug #25636784)

  • On Windows platforms, it was not possible to install to a path which contained spaces on any drive other than the C:\ drive.

    For example, trying to install to D:\Program Files\MySQL\Enterprise\Monitor failed, while C:\Program Files\MySQL\Enterprise\Monitor succeeded. (Bug #24482872)

  • The MySQL Enterprise Monitor Agent was not properly displayed as running and monitoring an instance. This occurred if it was stopped and it's monitored instance removed from the MySQL Instances dashboard, and then the MySQL Enterprise Monitor Agent was restarted.

  • Empty groups were not displayed on the Advisors page.

  • It was not possible to edit a replication group's description. The change was not saved.

  • A number of minor UI issues were corrected in this release. Issues such as double colons (::) in the system uptime frame, duplicated icons on buttons, and so on.

  • If an instance was renamed on the MySQL Instances dashboard, the instance name was not updated immediately elsewhere in the user interface.

  • The backup bar charts, Backup Run Time History and Backup Lock Time History, displayed extra zeroes after an upgrade from MySQL Enterprise Service Manager 3.2 to 3.3 or 3.4.

  • Custom filters which were not edited were displayed as edited on the Query Analyzer and graphs pages.

  • Under certain circumstances, graphs would not load on the Backup dashboard's History tab.

  • After an upgrade from MySQL Enterprise Service Manager 3.1, or 3.2, to 3.3 or higher, the Backup dashboard's Backup Run Time History and Backup Lock Time History displayed zeroes for instances monitored since before the upgrade.

  • Under certain circumstances, if a overrides were defined on MySQL instances in an advisor, both the parent and child schedules were evaluated for the overridden instance, instead of child schedule only. As a result, duplicate collections were performed and incorrect events displayed.

    The prompt has been updated.

  • Under certain circumstances, a monitored MySQL instance could be reported as having two, different server_uuid values. This could happen if the monitored instance was part of a replication topology, or installed in a docker container, and used Host Plus Data Directory from the MySQL Instance Identity Source menu.

  • Microsoft Windows 2016 Server systems were reported as Unknown.
