Dell Command | Monitor Version 9.1 User's Guide
Dell Command | Monitor architecture
Dell Command | Monitor data provider collects client system information data and stores the information in the proprietary Extensible Markup Language (XML) format. The data manager is a service that loads these providers based on request. Dell Command | Monitor CIM provider layer abstracts the interface to different CIMOM implementations. The input is a combination of XML and Extensible Stylesheet Language (XSL) data in proprietary form, while the output is a CIM object instance based on Management Profiles. The WSMAN that serves as the channel protocol, requests the data from CIMOM and transmits it to the console.
The
Dell Command
| Monitor
architecture
has several layers that are integrated with the Microsoft Windows
Management Instrumentation (WMI) stack:
- WMI application layer — Consists of management applications, standards-based management tools, and WMI applications such as Microsoft SMS, LANDesk, and WMI Tools. The applications in this layer are consumers of the system's management data supplied by Dell Command | Monitor . These applications request client information and send alerts through WSMAN/CIM Object Manager (CIMOM).
- WMI CIM Provider — Is available under CIMOM and contains
two CIM providers, which are registered with the CIMOM:
- The instance or method provider implements an interface that enables utility operations such as create, delete, modify, and query.
- The indication provider implements an interface for
WMI indications (events).
When the CIMOM receives a request for information, it routes the request to the appropriate provider. All providers exist in this layer, and they provide information on system devices. The providers send management application requests from the CIMOM to the data router.
- Data Manager — Loads data provider based on request from the upper layer.
- Data Provider — Collects system information like hardware, drivers, and operating system data , and stores them in the proprietary XML format.
The
Dell Command
| Monitor
architecture
has several additional layers that are integrated with the SNMP stack:
- SNMP agent — Shows the data received from the data manager as SNMP tables and traps.
- MIB — The MIB files store information about SNMP tables, its attributes and the available traps.
For example, a management console in the WMI application layer requests the available processor information on a client system. The WMI application layer makes the request over the network to the CIMOM on the client system. The CIMOM passes the request to the Dell Command | Monitor CIM provider and data manager. The data manager loads the corresponding data provider, which receives the information and stores it in a proprietary format. The information is then returned (through the same path in reverse) to the management console.
