Default Parameters for PureArrPerfTest

Using this test, administrators can figure out how well the FlashArray processes the I/O requests and detect delay encountered during processing the I/O requests. In addition, this test also reports the data utilization for performing read/write operations on the FlashArray. Using the metrics reported by this test, administrators can take remedial measures to keep a check on the irregularities, if any.

This page depicts the default parameters that need to be configured for the PureArrPerfTest test.

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• The eG agent collects the required metrics from the Pure Storage FlashArray by executing API commands using Pure Storage REST API on the FlashArray and pulls out critical metrics. In order to collect metrics, the eG agent should be provided with a valid API token. To know how to determine the API token, do the following:

  • Login to the Purity GUI as a user with administrator privileges.

  • Then, navigate to the System tab and click on the Users -> API Tokens. The API Tokens page will be displayed in the context-sensitive right panel. The API Tokens page displays a list of all users with API tokens and the dates on which the API tokens were created.

  • To view the API token of the created user, right click on that user. A drop-down list will appear next. Clicking the Show API Token option in that list reveals the API Token generated for the created user in a separate pop up window.

  • Copy this API token and specify the same in the API TOKEN text box while configuring the tests.

  Specify the determined API token in the API TOKEN text box.

• Once the above values are provided, click on the UPDATE button to 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.
