Performance Monitoring Using Nagios Core

Vinícius Prata Klôh; Mariza Ferro; Gabrieli Dutra Silva; Bruno Schulze

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 con gure Nagios Core to enhance it monitoring your local and remote host.
