This section documents all changes and bug fixes that have been applied since the release of MySQL Enterprise Monitor, version 2.0.3.
The Monitor Agent did not log connections to, and disconnects from, the monitored database.
This meant it was not possible to check if the Agent was connected to the database by simply looking at the log file. (Bug#42403)
The Monitor Agent failed to create the
mysql.inventory table. The logs displayed the
following error message:
(critical) (share/mysql-proxy/quan.lua:711) [proxy] please add SELECT permissions for this user on mysql.inventory to enable the QUAN feature, got Table 'mysql.inventory' doesn't exist
This happened even though the Monitor Agent used the
After installing Monitor Agent 126.96.36.19938 and then starting it
--version, the incorrect version was
displayed. Although 188.8.131.5238 was installed, the Monitor Agent
displayed the version number as 184.108.40.20638.
An invalid path was shown in the error message if the upgrade installer failed to find the previous install location.
The error message is shown below, note that the error message displays a different path to that provided by the user:
Please specify the directory that contains the previous installation of the MySQL Enterprise Monitor Agent Installation directory [/home/mysql/mysql/enterprise/agent]: /var/lib/mysql/agent Warning: The directory /home/mysql/mysql/enterprise/agent does not contain a previous installation. Please select the right installation directory.

The agent password error in the Service Manager did not log the originating host, making it impossible to determine the agent that failed to log in:
ErrorJan 5, 2009 4:56:08 PM<?xml version='1.0'?><exceptions><error><![CDATA[E1702: IncorrectPasswordException: [agent]]]></error></exceptions>
The Service Manager's JDBC connections did not have
sql_mode set to include
NO_ENGINE_SUBSTITUTION. This resulted in the
failure of Data Definition Language (DDL) if the Service Manager
was inadvertently pointed to an incorrect
A number of Advisor rules had advice text that had not been translated into Japanese. The Advisors that contained untranslated rules included Performance, Schema and Security. (Bug#42067)
Monitor Agent configuration files had global read privileges on the filesystem. (Bug#41794)
When the log files rotated to the maximum allowed by the
log4j configuration, the metadata contained
FileAppender became out of
synchronization due to a logic bug. This caused an assertion
error on any subsequent request for the logs tab or data.
SNMP trap messages were sending 127.0.0.1 as the IP address, and there was no feature to allow the user to configure the IP address contained in the SNMP message, which would have been useful for troubleshooting. (Bug#41361)
On all available test systems, including SUSE Linux Enterprise Server (SLES) 9 and 10 x86-32, x86-64, IA64, and Ubuntu 6.10 x86-64, the agent memory grew incrementally within ~3 hours to ~25M.
The agents then switched to the 'red' condition on the dashboard and no more data was reported. The agent processes were still alive.
This was also present in MySQL Enterprise Monitor version 220.127.116.1111 on Suse 7.3, with the glibc2.2 x86 agent.
There was no load on the monitored servers, and the problem also occurred when the “self-quan” was not configured. (Bug#41244)
Although the Monitor tab loaded initially, after a 64-bit MySQL server running a 32-bit MySQL Monitor Agent was clicked, a Null Pointer Exception was generated. (Bug#41164)
The Monitor Agent startup configuration did not seem to work and did not generate a log file. (Bug#40583)
An error generated by a rule failed to clear.
When a rule was created with the
os:disk:fs_used data item, if the instance
was not a valid mount point then the Monitor Agent reported the
2008-08-11 17:57:00: (critical) disk-get failed for all: 2
Note the above instance was for “all”, and similar results occurred for instance “disk”.
The issue was that upon editing the rule, or even deleting the rule, the agent still showed the above error type. Restarting the agent and the monitoring service failed to remove the error. (Bug#38709)
If the “On Save send test trap” checkbox was checked when the Save button was clicked and the locale was set to Japanese, an error occurred. The orange error banner was displayed at the top of the page with the error message in Japanese. (Bug#32069)
