Configuration of MariaCacheTest

This test monitors the key buffer cache in the Maria Database server and reports the number of physical reads of a key block, the number of read requests received by the cache and the number of key blocks that have been modified but not flushed to the cache. Using this test, administrators can figure out data mismatch between the cache and the disk and rectify the same before end users start complaining about outdated data from the disk.

The default parameters associated with this test are as follows:

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

• In the HOST text box, the IP address of the Maria Database server that is being monitored.

• Specify the port on which the server is listening in the PORT text box.

• Specify the name of the database that is to be monitored on the target Maria Database server in the DATABASE text box.

• The eG agent has to be configured with the credentials of a user who has server-wide PROCESS and SELECT privileges on the monitored Maria Database server. To know how to create such a user, click here.

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