Application scenarios for distributed management using SNMP expressions

Management distribution is an, we can say, old topic in terms of the number of proposed solutions and publications. Recently, the DISMAN workgroup suggested a set of MIB modules to address this matter in the context of SNMP. One of the DISMAN modules has the capability of using expressions to perform decentralized processing of management information – the Expression MIB. Although existing for some time now, its capabilities are not very well known. In fact, other DISMAN MIBs, such as the Schedule MIB and the Script MIB already got some attention in several papers and are target of very solid work. There are hardly any papers describing the Expression MIB and its functionality. This paper contributes to eliminate this absence by describing our implementation effort around it as well as some real world applications for it
