Default Parameters for 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figure out data mismatch between the cache and the disk and rectify the same before end users start complaining about outdated data from the disk.

This page depicts the default parameters that need to be configured for the MariaCacheTest test.

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

• 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.

• 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.
