Configuration of MariaLongRunQryTest

This test tracks the currently executing queries on a Maria Database server and determines the number of queries that have been running for a long time. This test also tracks the maximum time taken to execute the queries. You can also use the detailed diagnosis of this test to drill down to the exact queries that have been running for an unreasonably long time, and thus isolate the resource-intensive queries to the database.

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.

• In the ELAPSED TIME text box, specify the duration (in seconds) beyond which a query should have executed for it to be regarded as a long running query. The default value is 10.

• 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 Onoption 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 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.
