We are pleased to announce that MySQL Enterprise Monitor 3.4.3 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 Cluster
Carrier Grade Edition subscriptions.

You’ll find information about what’s new here:
(also included at the end of this note for convenience)

Highlights of MySQL Enterprise Monitor 3.4 include:

* The Replication Dashboard is extended to provide monitoring support
for Group Replication, which was introduced in MySQL Server 5.7.17.
The Topology view provides a visual representation of your group
replication topologies, and the Status drill downs are updated with
Group Replication-specific information. The status of the entire
group is reported on, also showing node failure tolerances and
whether Group Replication has quorum.

* New Group Replication Configuration and Group Replication Status
Advisors provide continuous analysis of the condition of your group
replication topologies. The Configuration Advisor checks for
misconfigurations which could lead to unstable or insecure
installations; the Status Advisor continuously monitors for servers
which go offline or fall out of sync with the other members of the

* The new Table Statistics report utilizes sys schema and its
schema_table_statistics view to show detailed table statistics in
both table and treemap forms. Available on MySQL 5.6 and above,
report details include total latencies, total number of rows
deleted, total I/O write requests.

* In general, the user interface page-loading times and page
responsiveness are improved in 3.4. In addition, time series graphs
are much faster in this release, particularly when you specify a
long time period. This graph performance improvement is gained by
continuous aggregation of time series data. If you are updating from
an earlier version, a one-time aggregation of your historic time
series data is performed when you first start the Service Manager
(as shown by a progress indicator next to the System Status

Changes in MySQL Enterprise Monitor 3.4.3

Functionality Added or Changed

* It is now possible to specify an exclusion list of users with
database-level privileges on all databases in the mysql.user table.
This is done using a regular expression in the MySQL User Account
advisor. An event is generated for any user which does not match the
defined expression.

For more information, see MySQL User Account (

Note: This change replaces the Non-root User Has DB, Table, Or Index
Privileges On All Databases advisor, and moves its functionality to
the MySQL User Account advisor. If you changed the scheduling or
thresholds on the Non-root User Has DB, Table, Or Index Privileges
On All Databases advisor, the changes will be lost after upgrading
to this version.

(Bug #26260456, Bug #11748288, Bug #25696565)

References: See also: Bug #17742263, Bug #26130781.

* The MySQL server, bundled with the MySQL Enterprise Service Manager,
has been upgraded to MySQL 5.7.19.

Important: Changes have been made to the prerequisites of MySQL

- must be present on Linux platforms. The MySQL
Enterprise Service Manager full and upgrade installers check for
the existence of this library.

- During a MySQL Enterprise Service Manager upgrade, the upgrade
installer runs the mysql_upgrade utility.

* The Tomcat server, bundled with the MySQL Enterprise Service
Manager, has been upgraded to 8.5.16.

* The bundled JRE was updated to 1.8.0_141 for both the Agent and
Service Manager.

* --mysql_ssl is no longer required by the MySQL Enterprise Service
Manager installer and has been removed.

* Data Purge settings have been added for aggregated data. For more
information, see Data Purge Behavior.

Bugs Fixed

* On the Advisors page, filtering for specific advisors did not return
all the advisors filtered for. (Bug #26668301)

* On Linux, Unix, and Mac OS X platforms, the agent installer did not
check the installation directory to ensure it had the required
permissions to install MySQL Enterprise Monitor Agent in that

As of this release, the installer checks the directory for the
appropriate permissions. If it does not have the rights to install
to that location, it returns the following error message:

There has been an error.
The current installation directory could not be accessed by non-root users.
Please select a different installation directory or change the permissions
to 755 for this directory.

(Bug #26551166)

* Sparkline graphs did not refresh dynamically.

* The Group Replication advisor, when expanded, listed MySQL instances
which were not involved in Group Replication.

* Under certain circumstances, if the server hosting MySQL Enterprise
Service Manager was restarted, MySQL Enterprise Service Manager
failed to restart, logging the following error: Error creating bean
with name 'groupReplicationMembership'.

* The Add a new graph drop-down menu was not displayed on the Overview

* It was not possible to open a selected range of a timeseries graph
in the Query Analyzer. The Query Analysis link did not behave as

* An error was displayed when selecting the Table Statistics report:
Unable to generate SYS Schema report for selected MySQL Server.

As of this release, the agent's Admin, General, and Limited users
are granted the EXECUTE privilege.

Important: If you defined these users manually, you must grant them
the EXECUTE privilege.

For more information, see Creating MySQL User Accounts for the
Monitor Agent.

* The Data Purge Behavior drop-down menus displayed Never if the
first-time setup was performed using the configuration utility, and
the purge values set to any value not divisible by 7.

The values were correctly defined, this was a display issue, only.

* Graphs were not included in the Support Diagnostics report.

* It was not possible to edit multiple advisors using the Edit
Selected button.

* Agent host names were not displayed in the list of agents on the
Advisors page, only the alphanumeric agent ID was displayed in
truncated form. This made it difficult to identify the agent.

As of this release, the agent is listed with the name of the host on
which it is installed, instead of the alphanumeric ID.

* Clicking on the Database Availability graph, on the Overview
dashboard, opened a blank page instead of the Events page.

* Under certain circumstances, such as filtering on many graphs on the
All Timeseries page, the resulting graphs were not correctly
populated with data. This was caused by the default value for the
maxHttpHeaderSize in the Tomcat configuration file, server.xml,
which is set too low for large quantities of data. The value is set
to 32K by default.

As of this release, the value of maxHttpHeaderSize is doubled, to
64K, and applied to both the SSL and non-SSL connector
configurations in server.xml.

If you are upgrading to this version from a previous version, you
must edit server.xml and add maxHttpHeaderSize="65536" to each of
the default connectors.

If you are performing a clean installation of MySQL Enterprise
Service Manager, you do not need to edit any files, the new values
are included by default.

* On Mac OS X platforms, the java_home_dir variable was not set
properly by the installer. As a result, the configuration report
contained the following error: ***unknown variable java_home_dir.

* On Linux, Unix, and Mac OS X platforms, the MySQL Enterprise Service
Manager upgrade installer could not upgrade the installation if the
installation directory contained files or directories created by a
different user, or a user with permissions which differed from those
of the user running the upgrade.

As of this release, the installers check the installation directory
to ensure all files and directories have the correct permissions. If
they do not, it exits with an informative error message.
