We are pleased to announce that MySQL Enterprise Monitor 8.0.3 is now available for download on the My Oracle Support (MOS) web site. It will also be available for download via the Oracle Software Delivery Cloud in a few days. MySQL Enterprise Monitor is the best-in-class tool for monitoring and management of your MySQL assets and is included with your MySQL Enterprise Edition and MySQL Enterprise
Carrier Grade subscriptions.

This is a maintenance release that includes a few enhancements and fixes a number of bugs. You can find more information on the contents of this release in the change log:
http://dev.mysql.com/doc/relnotes/mysql-monitor/8.0/en/news-8-0-3.html
(also included at the end of this note for convenience)

Highlights

* MySQL Enterprise Monitor 8.0 supports monitoring MySQL Server 8.0.11 and later. You can also use MySQL Server 8.0 as an external data repository for MySQL Enterprise Monitor 8.0.

* Significant improvements have been made to the performance and user interface of the Query Analyzer. When you click on a SQL statement, the new Statement Details page enables you to browse all example statements in the specified time range, rather than just the one with the worst run time. Drill into any of these examples to see their individual statistics, literals used, and EXPLAIN plan. Graphs display the execution pattern of the selected query during the specified time period.

* The new Global Memory Usage report builds upon the Memory instrumentation exposed within Performance Schema to provide greater insight into where memory is being allocated within the MySQL Instance - not just at the InnoDB Buffer Pool level, but for all memory allocations, across all connections and threads within MySQL. The report breaks down memory by allocation type, such as memory allocated for sorting, the buffer pool, or various other internal buffers used for statement processing.

Changes in MySQL Enterprise Monitor 8.0.3

Functionality Added or Changed

* The Tomcat server, bundled with the MySQL Enterprise Service Manager, has been upgraded to 8.5.34.

Bugs Fixed

* It was not possible to use the percentage character (%) in filter names. The filter was saved and was displayed in the list of available filters, but did not display the configured data when selected.
* Automatic page refresh did not pause if an asset was selected.
* Under certain circumstances, Out Of Memory errors caused the MySQL Enterprise Monitor Agent to restart. In the previous release, the default agent heap size, defined by the MEM_AGENT_JAVA_OPTS parameter in the setenv.sh/bat file, has been increased to 128MB.
Important
In the previous release, this issue was corrected for new installations. As of this release, this issue is also corrected for upgrades.
If you changed MEM_AGENT_JAVA_OPTS to a value greater than 128MB, the value is not changed by the upgrade. If you changed MEM_AGENT_JAVA_OPTS to a value lower than 128MB, the upgrade process updates the value to 128MB.
* Null Pointer Exceptions were logged relating to Query Analysis and Explain Plan when monitoring MySQL 8. These exceptions were caused by the removal of EXPLAIN EXTENDED in MySQL 8.
As of this release, MySQL Enterprise Monitor checks which MySQL version is being monitored and only attempts to use EXPLAIN EXTENDED on versions which support it.
