MySQL Enterprise Monitor 3.4 Release Notes  /  Changes in MySQL Enterprise Monitor 3.4.5 (2017-12-08)

Changes in MySQL Enterprise Monitor 3.4.5 (2017-12-08)

Functionality Added or Changed

  • The Tomcat server, bundled with the MySQL Enterprise Service Manager, has been upgraded to 8.5.23.

  • The bundled JRE was updated to 1.8.0_151 for both the Agent and Service Manager.

  • As of this release, on Solaris platforms, the installer and upgrade installer check for the presence of the Oracle Developer Studio 12.5 Runtime libraries. If these libraries are not installed, the installation stops and displays an error.


    The installer also checks for auto-mounted installations in /opt/developerstudio12.5.

    Oracle Developer Studio 12.5 Runtime libraries must be installed before running the MySQL Enterprise Monitor installers on Solaris.

  • The MySQL server, bundled with the MySQL Enterprise Service Manager, has been upgraded to MySQL 5.7.20.

  • The OpenSSL libraries used by the MySQL Enterprise Monitor installers and MySQL Enterprise Monitor Aggregator have been upgraded to 1.0.2m.

Bugs Fixed

  • The service_manager privilege descriptions lacked examples. For more information, see MySQL Enterprise Monitor Repository. (Bug #27130180)

  • The documentation incorrectly stated that a Service Manager user required privileges on the mysql.inventory table. The mysql.inventory table is no longer created. (Bug #27130103)

  • Some selections were not properly displayed in the Column drop-down menus on the Query Analyzer's Advanced filter. (Bug #27110602)

  • The bundled MySQL server did not include all the MySQL Enterprise Edition plugins, such as Audit and TDE, for Microsoft Windows platforms. The plugins were correctly delivered for Linux, Mac OS, and Solaris. (Bug #27110538)

  • The advice page for the Prepared Statements Not Being Used Effectively advisor incorrectly referred to the variables Com_stmt_prepare and Com_stmt_execute. The correct variables are Com_prepare_sql and Com_execute_sql. (Bug #26949933)

  • Timeseries graphs displayed old data, such as filesystems and network interfaces which were removed or no longer exist.

    As of this release, only recently reported, active assets are displayed in the timeseries graphs. (Bug #26942873)

  • It was not possible to refresh a replication topology using the Rediscover Replication Topologies button. An error was displayed. (Bug #26900106)

  • The link between two inactive nodes on the Replication topology view remained green, indicating an active connection. As of this release, links between inactive nodes are gray, indicating an unknown state. The same is now true for lines between active and inactive nodes. (Bug #26878020)

  • Topology did not correctly display nodes which were not running. They were displayed in Green, instead of Yellow, indicating that the replication thread was not running. (Bug #26871473)

  • Under certain circumstances, if you were upgrading to the previous version, it was necessary to edit server.xml and add maxHttpHeaderSize="65536" to each of the default connectors.

    As of this release, it is no longer necessary to manually edit server.xml, the upgrade installer checks and corrects the values automatically if they are set to a value less than 64K. If maxHttpHeaderSize is set to 64K or higher, the upgrader installer makes no changes. (Bug #26828438)

    References: See also: Bug #26391094.

  • It was not possible to select the last graph in the drop-down menu on the Overview dashboard. (Bug #26679583)

  • It was not possible to delete or edit a notification group if the subject contained braces, { or }. An error was displayed.

    As of this release, it is possible to edit, and correct, notification group subjects which contain unsupported characters. Also, an error is displayed on saving if the notification group's subject contains an unsupported character. (Bug #25535520)

  • Under certain circumstances, bulk schedule changes were not correctly applied to the replication advisors, Group Replication Configuration and Group Replication Status.

  • On the Advisors view, Filter and Expand filtered the advisor selection, but did not expand it as expected.

    Also, some Advisor controls were not correctly rendered after filtering.

  • Expanding the Filter, on any page which includes the Asset Selector, disabled the Asset Selector's Show All Assets checkbox, unless it was already enabled.

    If Show All Assets was not enabled, expanding the Filter forced the Asset Selector to reload and display only MySQL instances.

  • Under certain circumstances, the graphs in the Support Diagnostics archive could not be loaded in some browsers.

  • The graphs tab of the Query Analyzer's Query dialog was larger than the dialog which contained it.

  • The Group Name icon was not displayed correctly on the Email Notification Group page.

  • A rate limit exception caused a null pointer exception which stopped the MySQL Enterprise Service Manager from retrieving the sys schema version.

  • OS X 10.13 was not reported as Mac OS X (High Sierra), but as Unknown.

  • Data purge was not completed if the MySQL Enterprise Service Manager was restarted while the purge was running.

  • Several elements of the drop-down menus on the Query Analyzer were not displayed correctly.
