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.
