Configuration of MySQLInDbEngTest

This test monitors the InnoDB buffer pool and reports the amount of memory allocated to the buffer pool and the amount of memory utilized by the buffer pool. The statistics reported by this test help administrators analyze the usage of the buffer pool, and provides them with useful pointers to finetune the configuration of the buffer pool.

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 default configurations of tests, the values with “$” indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to “xyz*” and $port will be changed to “80” when configuring a test.
