Configuration of MySQLTabSpcTest

Tablespaces should be adequately sized. If not, then the tablespaces may frequently run very low on free space, causing all statements that attempt to acquire new space in the tablespace to fail. This in turn will result in serious performance issues ranging from slowdowns to shutdowns. Continuous monitoring of tablespace size and usage is hence important.

The MySQLTabSpcTest test auto-discovers the tablespaces managed by the target MySQL database server, and reports how well each tablespace is utilized. Using this test, you will be able to instantly identify the tablespace left with very little free space.

The default parameters associated with this test are:

• The TEST PERIOD list box helps the user to choose how often should the test be executed.

• In the HOST text box, specify the IP address of the host for which the test is to be configured.

• In the PORT text box, specify the port at which the specified host listens.

• In the DATABASE text box specify the name of a database on the target MySQL database server being monitored.

• The eG agent has to be configured with the credentials of a user who has server-wide Process and Select privileges on the monitored MySQL server. Specify the credentials of such a user in the USERNAME and PASSWORD text boxes. To know how to create such a user, refer to Pre-requisites for Monitoring the MySQL Server topic in the Monitoring MySQL Server document.

• Confirm the password by retyping it in the CONFIRM PASSWORD text box.

• If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS check box will appear in this page. Clicking on this check box will allow you to apply the configuration to all/selected components of that type.

• Once the above values are provided, click on the UPDATE button to register the changes made.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of “none” in the parameter value indicates that the corresponding parameter value can be changed if required.
