Configuration of MySQLCltStsTest

This test reports the count of nodes in the target MySQL database cluster and indicates the number and names of those nodes that are currently available. This way, the nodes that are unresponsive/unreachable can be identified. The test also reports the nodes that are in recovering state. Using this test, administrators can figure out if only very few nodes in the cluster are available to service the client requests to the cluster. This signals a potential overload.

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.

• Specify the full path to the location where the target MySQL Cluster manager is installed in the MCMPATH textbox. For example, your location can be C:\Users\user\AppData\Roaming/mcmd.conf. By default, none is specified against this parameter.

• To make diagnosis more efficient and accurate, eG embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test, by default, for a particular server, choose the On option against DETAILED DIAGNOSIS. To disable the capability, click on the Off option.

  The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability.

  • Both the bad and normal frequencies configured for the detailed diagnosis measures should not be 0.

• 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.
