Highlights=20

* 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.=20

* 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.=20

* 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.=20

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.
