This test monitors the CPU and RAM usage of and threads executed within each data mover in the DME, and proactively alerts administrators to the over/under-utilization of the CPU resources, the steady/rapid erosion of RAM, and operational bottlenecks such as blocked threads. This way, the test warns administrators of an impending slowdown in data mover performance, and enables them to initiate measures to prevent the anomaly well before it affects user experience with the storage system as a whole.

The default parameters associated with this test are as follow:

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

• In the HOST text box, the host name of the component for which the test is to be configured has to be specified.

• The Control Station is the management station for the VNX for File system, and enables control and configuration of the system. The eG agent uses the CLI that runs on the Control Station to monitor and manage the performance of the VNX for File system. To enable the eG agent to use this CLI, specify the IP address of the Control Station in the CONTROLLER STATION IP text box. By default, the IP address of the HOST will be displayed here.

• 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 components, 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.
