Abstract

Even though monitoring tools are essential to the management of communications networks, Open Source applications still confront their potential users with considerable problems. This work analyses the limitations of the currently existing tools and presents the development of a new tool that solves most of those problems. The tool is based on a new architecture of objects and remote method invocation and allows both centralized and distributed monitoring. Its configuration through web interface, its support to monitoring templates, and its flexibility make it particularly interesting for a large number of users in search of a strong but easily configurable system. The proposed extension system is based on plug-ins and it is highly innovative because of its power and simplicity. Finally, the configuration simplicity and other essential improvements of the proposed system are successfully tested in a real environment.

State Of The Art

In spite of numerous efforts in recent years, during which the Open Source monitoring applications have improved considerably, a number of limitations persist and essential features are still lacking or are too complex for many users.

This work analyses various open source applications, in particular a subset of the most complete and/or popular ones, whose characteristics can be seen in Table 1.
