Changes in MySQL Enterprise Monitor 3.4.8

Functionality Added or Changed

* The installers were updated with improved Japanese and Chinese

Also, to better support Japanese installations, the
configuration_report files, generated by the installer, now use the
utf8 character set.

* The OpenSSL libraries used by the MySQL Enterprise Monitor
installers and MySQL Enterprise Monitor Aggregator have been
upgraded to 1.0.2o.

* The MySQL server, bundled with the MySQL Enterprise Service Manager,
has been upgraded to MySQL 5.7.23.

* The bundled JRE was updated to 1.8.0_181 for both the Agent and
Service Manager.

Bugs Fixed

* Changes to the Query Analysis Reporting advisor's configuration were
ignored by the built-in agent of the MySQL Enterprise Service
Manager. The changes were created correctly, but the built-in agent
continued using the default schedule and configuration.

Important: This issue affected the built-in agent of the MySQL
Enterprise Service Manager only. It did not affect the standalone
MySQL Enterprise Monitor Agent.

For information on this distinction, see MySQL Enterprise Monitor
Component Overview.

(Bug #27986851)

* The plus character (+) was added to search criteria on the Query
Analyzer filter's Value field. These characters were added if a
search was performed, the Details page was opened for one of the
seach results, then the Query Analyzer page was opened again.

For example, searching for INSERT INTO `mem__quan` resulted in the
string INSERT+INTO+`mem__quan`.

* The agent upgrade option, --ignore-old-proxy-aggr was present in the
MySQL Enterprise Monitor Agent and documentation. The upgrade from
MySQL Enterprise Agent Proxy Service 2.3 is no longer supported.

* If the configuration of the Query Analysis Reporting advisor was
changed, for example by disabling, then reenabling, the Example
Query or Explain, the Auto-Explain Threshold value was set to zero
instead of to the default value of 100 milliseconds. This resulted
in an error and no new queries were displayed on the Query Analyzer.

* The Example Statements configuration message, displayed if
EXAMPLE/EXPLAIN query was not enabled, incorrectly referenced
performance_schema_events_statements_history_size instead of

* If the data retention policy was set to zero, or a negative value,
and the MySQL Enterprise Service Manager was upgraded, the upgraded
MySQL Enterprise Service Manager failed to start.
