Default Parameters for NutClusStrPoolTest

The NutClusStrPoolTest test reports these statistics for each storage pool that is managed by the Nutanix Prism. With the help of this information, administrators can proactively detect a potential space contention, an I/O overload, and even processing latencies that may impact storage performance, and can initiate measures to avert them. Additionally, the test also measures and reports the effectiveness of the storage optimization methodologies that are applied currently.

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

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

  • To connect to the Nutanix Prism and collect metrics from it, the eG agent should be configured with the credentials of a Cluster administrator or a User administrator. This is why, you need to specify the name and password of such a user in the NUTANIX PRISM USER and NUTANIX PRISM PASSWORD text boxes, respectively. However, some high security Nutanix environments may prefer not to expose the credentials of a Cluster administrator or a User administrator. In such environments, the eG agent can be configured with the credentials of a Prism user with the Viewer role. To know the steps for creating such a user, click here.

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

  • By default, the Nutanix Prism server is SSL-enabled. Accordingly, the SSL flag is set to Yes, by default. This indicates that the eG agent will communicate with the Prism server via HTTPS by default.

  • By default, the Nutanix Prism server listens on port 9440, which appears in the WEBPORT parameter. This implies that while monitoring a Nutanix Acropolis server via the Prism server, the eG agent connects to port 9440.

  • The DD FREQUENCY refers to the frequency with which detailed diagnosis measures are to be generated for this test. For a Nutanix Acropolis Prism server, this is set to 1:1 by default. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem.

  • 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.
