Configuration of MySQLIndbIOTest

This test monitors reads from the redo log files and writes to disk. Using this test, administrators canfigure out which type of operations is pending frequently on the redo logs - is it reads? or writes? or fsync() operations? In the process, the test proactively alerts administrators to potential latencies in reading from and/or writing to disk.

The default parameters associated with this test are:

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• In the HOST text box, specify the HOST for which this test is to be configured.

• In the PORT text box, specify the port at which the target host is listening.

• The test uses a database on the monitored MySQL server. Specify the name of the database in the DATABASE NAME text box.

• To monitor MySQL database server, the eG agent should be configured with the credentials of a user with server-wide Process and Select privileges. Specify the name of user in the USER text box. Specify the password of the specified user in the PASSWORD text box. To know how to create such a user, refer to Configuring the eG Agent with Access Privileges section of 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 button will appear in this page. Clicking on this button will allow you to apply the configuration to all/selected components of that type.

• Once the necessary values have been provided, clicking on the UPDATE button will 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.
