Functionality Added or Changed
The MySQL Enterprise Monitor Proxy and Aggregator is delivered with this release. This package works without the need of an agent to communicate with the Service Manager, using a new plugin infrastructure that allows the Proxy to send raw query statistics to the Aggregator, to then aggregate out of band of client connections, saving memory and processing overhead for client statements.
The MySQL Enterprise Monitor Proxy and Aggregator is not yet available on Microsoft Windows platforms. This changelog will be updated when the Windows version is available.
The MySQL Enterprise Monitor Proxy and Aggregator is delivered as a separate installation package.
If you are using the 2.3 Proxy/Aggregator installation with a 3.0.x version of MySQL Enterprise Service Manager, you must uninstall the 2.3 version of the Proxy/Aggregator before installing MySQL Enterprise Monitor Proxy and Aggregator delivered with this version.
Changes were made to many configuration settings. Your existing scripts or batch files may not work with the new configurations. It is highly recommended you read the updated Proxy and Aggregator documentation delivered with this release before installing the new MySQL Enterprise Monitor Proxy and Aggregator.
The MySQL Enterprise Monitor Proxy and Aggregator supports
EXPLAIN for the
DELETE DML statements.
EXPLAIN on these statement types is
supported for MySQL 5.6.3 and higher.
The bundled JRE was updated to 1.7.0_67 for both the Agent and Service Manager.
As of this release, an options file is delivered, setenv.sh/setenv.bat, which enables you to specify minimum and maximum heapsize, and log dump settings when running the agent from agent.sh/agent.bat.
This file is installed to the
of your Agent installation. Any custom settings added to this
file are preserved during upgrades of the Agent.
The performance of the File System Free Space advisor has been improved.
Clicking Reload on the InnoDB Buffer Pool Usage report displayed the Generate Report page instead of reloading the report. As of this release, clicking Reload reloads the report. (Bug #19286607)
Under certain circumstances, the asset list did not load correctly. This issue only occurred when using the Firefox browser to view the MySQL Enterprise Monitor User Interface. (Bug #19217939)
If monitoring large installations, the Database Availability graph on the Overview dashboard could take a long time to load. As of this release, the underlying queries used to populate this graph have been optimized to enable much faster loading times. (Bug #19064180)
If a replication group was automatically deleted, it was not possible to edit an Event Handler which used that Replication Group. It was only possible to delete the Event Handler.
Under certain circumstances,
queries performed on the Inventory table resulted in a large
number of temporary disk tables.
Under certain circumstances, the HTTP timeout values were overridden and both connection and socket timeout values could be set to infinity.
