Network management views using delegated agents
German S. Goldszmidt · 1996
The lack of an appropriate external data model is one of the reasons for the dearth of effective network management applications. Many network management computations over Management Information Bases (mibs ) cannot be practically accomplished through remote interactions. This paper describes the design of an mib Computations System that supports the dynamic definition of external data models for mibs. The system consists of a View Definition Language (vdl) to specify mib external views and snmp-agent extensions that implement them. vdl views define new mib variables, which are computed via instrumentations performed by a Management-by-Delegation (m b d) server, and which can be queried via the Simple Network Management Protocol, (snmp). 1 Introduction Network management applications need to compute useful information from raw data collected in Management Information Bases (mibs). Often such computations cannot be accomplished through remote interactions between the application and th...
