Monitoring and Reporting are an integral part of IT infrastructure. Lack of single tool that covers all the need for monitoring in an organization has led to uses of different kinds of monitoring tools within an organization. Existence of diverse monitoring toolshas led to significant heterogeneity in an infrastructure between the tools and the data they measure.The monitoring tools generally differs in the data structures and interaction interfaces that they implement. One of the key issue in todays monitoring scenario is the interoperability between several monitoring system and the heterogeneous data they produce.In this thesis some of the current monitoring problems that arises due to diversity in monitoring tools are briefly discussed. It also discusses how a standard common data model can benefit the interoperability between the tools. The implementation of simpleproof of concept integration between selected monitoring tools is also explored. The results of implementation indicates the benefits of information interchange between the tools for solving many problems or difficulties that are discussed. The thesis also addresses some challenges in data integration between different tools.
