Windows Management Instrumentation providers
WMI is a set of extensions to the Windows Driver Model that provides an operating system interface through which instrumented
components provide information and notification. WMI is Microsoft's implementation of the Web-Based Enterprise Management (WBEM)
and Common Information Model (CIM) standards from the Distributed Management Task Force (DMTF) to manage Server hardware,
operating systems and applications. WMI Providers helps to integrate with Systems Management Consoles such as Microsoft System
Center and enables scripting to manage Microsoft Windows Servers.
You can enable or disable the WMI option in iDRAC. iDRAC exposes the WMI classes through the iDRAC Service Module providing the
server’s health information. By default, WMI information feature is enabled. The iDRAC Service Module exposes the WSMAN monitored
classes in iDRAC through WMI. The classes are exposed in the root/cimv2/dcim namespace.
The classes can be accessed using any of the standard WMI client interfaces. For more information, see the profile documents.
The following examples use the DCIM_account class to illustrate the capability that WMI information feature provides in iDRAC Service
Module. For the details of the supported classes and profiles, see the WSMAN profiles documentation available at Dell TechCenter.
