The DMTF's CDM Forum is dedicated to uniting the computer industry on a single interoperable interface to all system diagnostics.

The Common Diagnostic Model (CDM) specification is widely used within the industry to evaluate the health of hardware systems in multi-vendor environments. The CDM Forum will extend these capabilities by helping deliver additional compatibility in cross-platform system diagnostics through the CDM Conformance programs.

CDM creates diagnostic instrumentation that can be utilized by platform management applications, and its tight synergy with the other models in the DMTF’s Common Information Model (CIM) enables further integration of diagnostics into critical management functions. By developing the CDM Certification Program, the CDM Forum will provide new levels of interoperability to help drive automation in support of end users’ grid and utility computing objectives.

The Common Diagnostic Model (CDM) Initiative was created to unify the computer industry on a single interoperable, secure, and functionally rich interface to diagnostics programs on multi-vendor computer systems. The CDM Initiative brings together the vast resources of the DMTF to fundamentally improve the efficiency of the computer industry in delivering more advanced software solutions as well as directly decrease the cost of datacenter management. CDM is based on the Common Information Model (CIM) and Web Based Enterprise Management (WBEM) standards from the DMTF.

Forum Membership

DMTF Forums pursue work of interest to a subset of DMTF members. Participating in Forums allows member companies to benefit by uniting with other members to share the costs of joint initiatives and together succeed at their stated mission. Membership in the DMTF does not automatically grant membership in a Forum, however, a member of a Forum must also be a member of the DMTF.

Membership in the CDM Forum, which is granted at the company level, results in a number of valuable privileges. The CDM Forum has two levels of forum membership: Leadership and Participatory. Annual membership dues are $25,000 for the Leadership Level and $10,000 for Participatory membership.
