Configuration of HiVSPCachePRTest

This test reports the percentage of data that is yet to be written to the cache, and thus sheds light on a potential cache overload or a slowdown while writing data from the cache to the disk.

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.

• Specify the host for which the test is to be configured in the HOST text box.

• Specify the port at which the device listens to in the PORT text box. By default, this is NULL.

• To extract metrics from the target storage device, the eG agent should be configured with the credentials of a special user account, which is specifically created for use with the Java export utility. This user account should fulfill the following conditions:

  • Should not possess the ‘write’ permission;
  • Can be of any user type; however, to ensure that the eG agent collects statistics pertaining to all storage partitions, it is recommended that this user is of type storage administrator;
  Specify the credentials of such a user in the USERID and PASSWORD text boxes.

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

• Specify the time duration (in seconds) beyond which this test should time out in the TIMEOUT text box. The default is 10 seconds.

• 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 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.
