Subject:MySQL Enterprise Monitor 4.0.0 GA has been released
View as plain text  
We are very happy to announce the general availability of MySQL
Enterprise Monitor, Version 4.0. 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.

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


* Modern look and feel: a redesigned user interface delivers a vastly
   improved overall user experience. The visible changes--the layout,
   the icons, the and the overall aesthetics--provide a more natural
   and intuitive experience. Views dynamically change and adjust to
   your current context and the assets you've selected, everything from
   individual MySQL instances or hosts to your custom Groups, to your
   complex replication and clustered topologies. Additional
   enhancements include a much more responsive UI and a greater
   capacity to scale, allowing you to more effectively manage thousands
   of MySQL related assets.

* MySQL Cluster monitoring: we now auto-discover your MySQL Cluster
   installations and give you visibility into the performance,
   availability, and health of each MySQL instance and NDB process, as
   well as the health of the MySQL Cluster instance as a single logical
   system. The Overview dashboard displays detailed instrumentation
   available for each MySQL Cluster and the Topology dashboard displays
   the current configuration of your MySQL Cluster enabling you to
   quickly see the status of the MySQL Cluster instance as a whole and
   each individual process. The Topology dashboard allows you to easily
   see how your MySQL Cluster installations are currently functioning.

* A User Statistics report: which provides an easy way to monitor
   MySQL resource utilization broken down by user.

Changes in MySQL Enterprise Monitor 4.0.0

NDB Cluster Monitoring

* Important Change: MySQL NDB Cluster monitoring has been added in
   this release for NDB Cluster 7.5.7, or higher.

   The following changes were made to support it:

   - Overview was extended to provide detailed information on NDB
     Cluster nodes.

   - Advisors were updated.

       The following NDB Cluster advisors were added in this release:

       NDB Cluster Memory Usage:

       NDB Cluster Status:

   - All existing Cluster advisors were renamed with the prefix NDB

   - The following advisors were removed and their functionality rolled
     into the NDB Cluster Memory Usage advisor:

       Cluster Data Node Data Memory Getting Low

       Cluster Data Node Index Memory Getting Low

   - The following advisors were removed and their functionality rolled
     into the NDB Cluster Status advisor:

       Cluster Data Node Has Been Restarted

       Cluster Data Nodes Not Running

       Cluster Has Stopped

   - Discovery of ndbd, ndbmtd, and ndb_mgmd processes.

   - Events view is extended to support MySQL NDB Cluster. Events are
     now generated for NDB Data Nodes, Management Nodes, and API Nodes,
     as well as MySQL instances and hosts.

   - The Topology view is updated to support NDB Cluster topologies.

   - An NDB Cluster Memory Usage report is added in this release. For
     more information, see NDB Cluster Memory Usage. The report is
     based on the output from the ndbinfo.memory_per_fragment table.
     For more information, see The ndbinfo memory_per_fragment Table.

User Interface Enhancements

* Important Change: The user interface was extensively redesigned.

   - A navigation bar is added to the left side of the interface. All
     functional navigation is now performed through this navigation

   - The Overview was extensively redesigned. See Overview for more

   - The Asset Selector was replaced with target selection fields which
     establish a context for all data displayed in the application. For
     example, if you select a single MySQL instance, only the data for
     that instance is displayed for all views. See Target Selection for
     more information.

     The target selector fields are persistent and present for all

     See Target Selection for more information.

   - The Settings menu (gear icon), is removed. All its contents are
     now grouped under the Configuration section of the navigation bar
     on the left side of the interface.

   - The Roles and Users views are updated in this release.

* The Create Event Handler dialog's Filter section was redesigned.
   Also, the Group and Assets columns in the Event Handler list are
   combined into the Subjects column.

   For more information, see Creating Event Handlers.

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.

* A User Statistics report is added in this release. For more
   information, see User Statistics. The report is based on the user
   summary sys schema views. For more information, see The user_summary
   and x$user_summary Views. (Bug #18888933)

* 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 
     to 755 for this directory.

   (Bug #26551166)

* If the Asset Selector was collapsed, there was no indication of
   which asset was selected. (Bug #25252032)

* It was not possible to filter a group twice in the Asset Selector.
   (Bug #20584984)

* Auto-refresh interfered with menu selection. (Bug #11748623)

* 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.

* 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.

* Under certain circumstances, it was not possible to montor an
   instance which had previously been monitored and then deleted by
   MySQL Enterprise Service Manager.

* Graph data was not displayed for intervals of four or more days if
   the interval was defined on a combined graph.
