Monitoring is always carried out with a purpose in mind. The general aim is to obtain information in order to construct a model of system behaviour or to modify an existing model. The general activity of monitoring a system can be specialized to a particular purpose such as accounting, debugging or testing, among others. Distributed systems (DSs) are used in an increasing number of domains, such as research, industrial and social environments. Now work environments and peoples are distributed across multiple organization and geographical boundaries. Monitoring is done to track the activities of this distributed system and that information is stored for Future use. This paper addresses the monitoring of distributed system, monitoring impacts in distributed systems and reusability of monitored information. Key Terms: - DSs; Monitor; Activities; Reusability; RSA I. INTRODUCTION Monitoring is carried out in order to obtain information about a system, and in general, monitoring is part of the process of management. Among the many activities which involve monitoring are debugging, testing, accounting, performance evaluation, resource utilisation analysis, and security and fault detection. Monitoring is concerned with providing the necessary information in order to allow the construction of the required model of the observed system and its presentation. It is the purpose of monitoring which dictates what should be observed and also how the information is to be obtained. Every system is affected by being monitored. The extent of the influence may or may not be negligible from the point of view of the user(s) or the observer(s) of the system. There is a relation between the flexibility of the monitoring facilities, the cost of implementation, and the extent to which they interfere with the behaviour of the system. Certain problems associated with monitoring in a centralized system are exacerbated when dealing with distributed systems. The following are the problems encounter during monitoring of distributed systems which includes, no central point of control, no central point of observation, incomplete observability, non-determinism, monitoring interference, replication, migration, and monitoring as a distributed activity. The monitoring of a distributed system is itself a distributed activity and it therefore requires tools which allow the management of the process of monitoring access and use to remote resources. II. LITERATURE REVIEW Distributed system consists of a group of computers connected together by a computer network in order to exchange information [1]. They communicate with each other using messages, pieces of information transferred
