Nagios is configured by building configuration files for each machine which is usually done to monitor small number of systems. The configuration of Nagios can also be automated by using shell scripting which is generally done in an industry, where the numbers of systems to be monitored are large. Both the above methods of configuration have been implemented in this project. The project has been successfully used to know the status of each service running on the defending team’s network.

    Performance Monitoring Using Nagios Core HPC4e-ComCiDis Vin´ıcius P. Kl^oh Mariza Ferro Gabrieli D. Silva Bruno Schulze LNCC { Petr´opolis,RJ Abstract The High Performance Computing for Energy (HPC4e) project aims to apply\new exascale HPC techniques to energy industry simulations, customizing them if necessary, and going beyond the state-of-the-art in the required HPC exascale simulations for different energy sources that are the present and the future of energy like, wind energy production and design, efficient combustion systems for biomass-derived fuels (biogas), and exploration geophysics for hydrocarbon reservoirs". Beyond the general objective, there are specific technical objectives that will be developed to enhance the final results. Our objective is study the mapping and optimization of the codes proposed for simulations in energy domain (atmosphere, biomass and geophysics for energy), analysing all the aspects related with the performance of these simulations' codes. Trying to meet all these objectives, we are investigating performance tools that would help our research. We investigated at first tools that enable online measurement of performance (online approaches are without code instrumentation). More specifically, in this work we present our initial work with Nagios and the hard begin to put this performance tool on work. In this work we present the steps and instructions, on how to install and configure Nagios Core to enhance it monitoring your local and remote host.

    Annals of the University of North Carolina Wilmington Master of Science in Computer Science and Information Systems GNU RADIO AND THE USRP AS A SOLUTION FOR REMOTE EMERGENCY MONITORING Douglas Casey Tucker A Capstone Project Submitted to the University of North Carolina at Wilmington in Partial Fulfillment of the Requirements for the Degree of Master of Science Department of Computer Science Department of Information Systems and Operations Management University of North Carolina at Wilmington 2009 Approved by Advisory Committee Accepted By _______________________________ Dean, Graduate School Abstract GNU Radio and the USRP as a solution for remote emergency monitoring. Douglas Casey Tucker, 2009. Capstone Paper, University of North Carolina at Wilmington. Software-Defined Radio (SDR) is a field that has emerged to solve the problem of interoperability between differing radio frequency (RF) communication standards. Instead of requiring different hardware for each waveform as in traditional analog radio, SDR attempts to provide a more hardware-independent solution by moving the software closer to the antenna. In this document the author presents the case of an information providing company whose goal is to expand into remote locations, the evolution of its operations from low-tech to high-tech automated information systems, and its interest in a particular application of SDR in conjunction with streaming audio and Voice over IP (VoIP) services. 2 Table of Contents 1.
