Alert Standard Format (ASF) Specification
Version 2.0
23 April 2003
Abstract
The term “system manageability” represents a wide range of technologies that enable remote
system access and control in both OS-present and OS-absent environments. These technologies
are primarily focused on minimizing on-site I/T maintenance, maximizing system availability and
performance to the local user, maximizing remote visibility of (and access to) local systems by I/T
managers, and minimizing the system power consumption required to keep this remote
connection intact. The Distributed Management Task Force (DMTF) defines Desktop
Management Interface (DMI) and Common Information Model (CIM) interfaces that operate when
the managed client is fully operational in its OS-present environment. This specification defines
remote control and alerting interfaces that best serve the clients’ OS-absent environments.
