An Adaptable Capability Monitoring System

摘要

SNMP-based monitoring systems are founded on a platform with precompiled agents in the managed node. Software updates and re-configuration are not flexibly handled. This paper presents a solution for monitoring by use of a service framework for adaptable service systems in cooperation with traditional SNMP agents. A two-level manager system consisting of Main monitoring managers and Intermediate monitoring managers executes on TAPAS (Telematics Architecture for Play-based Adaptable Systems) platform for adaptable service systems. The Intermediate monitoring managers are federated managers that communicate with ordinary precompiled SNMP agents by using SNMP protocol. The manager part of the monitoring system will have flexibility both with respect to software updates and re-configuration. The managers are TAPAS role figures. Role figures can be deployed, instantiated and moved during run-time. This feature can be used in overload and fault situations. Some experimental results are presented for cases where the Main monitoring manager is autonomously moved after failure.
