Introduction 7 Introduction The Dell™ OpenManage™ Client Instru mentation (OMCI) software enables remote management application programs to access client system information, monitor the client system status, or chang e the state of the cl ient system; such as shutting it down remotely .
8 Introduction • The CIM data model abstracts and de scribes all elements in a network environment. The CIM schema provides the actual data model descriptions and arranges the network into a series of managed objects, all interrelated and broadly classified.
Introduction 9 OMCI uses a variety of data sources resident on the client system which includes: • Microsoft W in32 WMI providers •S M B I O S • Device drivers • Operating system registry • .
10 Introduction F or example, a management console in the WMI application layer r equests the available free space on the client sy stem hard drive. The WMI application layer makes the r equest over the netwo rk to the CIMOM (in the Dell WMI provider layer) on the client system.
Introduction 11 Features The following are k ey features of OMCI: • CIM 2.6 Schema Support • Dell LegacySelect 2.0 Support • Remote Boot Device Select • WMI Security • Event Reporting • Remote Shutdown • Remote W ake-Up Configurability • WfM V ersion 2.
12 Introduction A network administrator can change the settings of these components either through the computer's system setup or by using a WMI management application. NOTICE: Changing LegacySelect attributes such as Integrated Drive Electronics (IDE) Controller may cause a computer sy stem to become unusable.
Introduction 13 processes that may be running. If the temperature incr eases too quickly and OMCI does not poll the system in ti me, it will not generate a shutdown message and the system will not shut down cleanly . OMCI also contains a start delay for the polling intervals.
14 Introduction • Additional Display Device Information: Earlier OMCI releases provided limited display device informati on. OMCI 7.6 also provides the manufacture date in <yyyy W eek ww > format; y-year , w-week number (for example, 2008 W eek 16) and the po ssible sleep states of the monitor .
Introduction 15 Other Dell Documents Y ou Might Need In addition to this User's Guide , you can find the following guides either on the Dell Support website or on the Systems Management T ools an.

Alerts 31 Alerts Overview Alerts are generated when a system’s state of inter est changes. There are two basic types of alerting: local alerting to the current computer user and r emote alerting to a management applic ation. Dell™ OpenManage™ Client Instrumentation (OMCI) handle s both types of alerting.
32 Alerts The system network interface card (N IC) and basic input/output system (BIOS) support ASF 2.0. If the BIOS allows for any ASF 2.0 configuration, then the BIOS settings are e xposed through the Microsoft ® W indows ® Management Instrumentation (WMI) by OMCI.
Alerts 33 Y ou are also provided with an option to r eceive either a single alert or a limited number of alerts of the occurrence of an event, of a given type. Y ou can mask out specific events and can generate single alert mes sages for on ly th ose e vents .
34 Alerts The following properties in the Dell_Configuration class allows you to control the notices sent to the NT event log and to the local display based on the severity of the event: • GlobalNTE.
Alerts 35 The lowest WMI severity level that OMCI sends is W ARNING_DEGR ADED and the highest is CRITICAL. The severities of OMCI 7. x events are listed in T able 4-1. OMCI sends local alerting and remote alerting for al l the listed events. . T able 4-1.
36 Alerts DiskCapacity (105) One of the hard drives is running out of free space. In OMCI 7.0, only one user -defined threshold is used. The threshold is expr essed as an absolute value in megabytes (MB). The default value is 50 MB. An event is generated when available free space on one of the hard drives falls below this threshold.
Alerts 37 1 The event is specific to OMCI 7.0. 2 The event is specific to OM CI 7.1 and later versions. MemorySizeIncreased (103) The memory size has been increased. 2 W ARNING_DEGR ADED 3 MemorySizeDecreased (104) The memory size has been decreased. 2 W ARNING_DEGR ADED 3 NumberOfDisksDecreased (102) A hard d rive has been rem ove d.
