timer that continuously counts down. The Health Monitor frequently reloads the counter to prevent it
from counting down to zero. If the ASR counts down to zero, it is assumed that the operating system has
locked up and the system automatically attempts to reboot.
You can perform automatic system recovery operations such as reboot, power cycle, or power off the
server after a specified time interval. This feature is enabled only if the operating system watchdog timer
is disabled. If OpenManage Server Administrator is installed, this monitoring feature is disabled to avoid
duplicate watchdog timers.
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 example is using 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.
