Configuration of EMCCtraNodeTest

For each node, this test reports the status of the node, space available and space used. By closely monitoring the performance of each node, administrators may be alerted to investigate the reasons for the space crunch, and resolve the issue before the overall performance of the storage system gets affected.

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 specified host listens.

• In order to monitor an EMC Centera Storage, the eG agent has to be configured with the credentials of a read only user. Specify the login credentials of such a user in the USER AND PASSWORD text boxes.

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

• Provide the path of CenteraViewer on agent host in CERTERAVIEWER JAR PATH. CenteraViewer is installed along with CenteraCLI. By default the installation path is C:\Program Files\EMC\Centera\2_4\SystemOperator\lib\CenteraViewer.jar

• Specify the time duration (in seconds) beyond which this test should time out in the TIMEOUT SECONDS text box. The default is 120 seconds.

• 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.
