IBM Tivoli Monitoring implements the Common Information Model (CIM) standard from the Distributed Management Task Force (DMTF). CIM is a model for describing management information in a network environment. The model applies the basic techniques of the object-oriented paradigm.
To obtain data from the monitored resources, IBM Tivoli Monitoring might use processes included in the endpoint's operating system. On Windows systems, it uses the Windows Management Instrumentation (WMI), which is Microsoft's implementation of CIM. On UNIX, Linux, and OS/400 operating systems, the information collection agent is incorporated in the IBM Tivoli Monitoring endpoint engine based on CIM specifications.
The service object API enables the resource model scripts to use CIM objects, monitoring collections, and custom scripts in any combination. WMI (on Windows) and the CIM Object Manager (CIMOM on other supported operating systems) are responsible for loading the providers that retrieve performance and availability data from system and application resources. At the provider layer, an Instrumentation Library Type (ILT) interface is provided, using a parameters passing mechanism. The CIM provider is implemented by an ILT Manager for Java.
