Configuration of MySQLCluUsrPrsTest

This test reports the number and state of the processes of each user who is currently connected to the MySQL Cluster server. Using the metrics reported by this test, administrators can promptly isolate idle processes, which are a drain on a server's resources.

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 name of a database on the target MySQL Cluster database server being monitored in the DATABASE NAME text box.

• To monitor MySQL Cluster database server, the eG agent should be configured with the credentials of a user with server-wide PROCESS and SELECT privileges on the monitored MySQL Cluster database server. To know how to create such a user, refer to Pre-requisites for Monitoring the MySQL Cluster Database Server topic. Specify the name and password of such a user in the USER NAME and PASSWORD text boxes.

• Confirm the Password by retyping it in the CONFIRM PASSWORD text box.

• Specify the time duration (in seconds) above which the processes that are waiting in the database will be regarded as idle in the IDLE TIME text box.

• 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.
