= Introduction to the project =
[[TracNav]]

The PowerMon project concerns the acquisition and the publication of data on the power consumption of LAL^1^'s Data Center (Laboratoire de l'Accélérateur linéaire) , member of GRIF (Grille de Recherche d'Ile de France) and the EGEE^2^ grid.

The project will thus relate to the creation of the first whole publicly available data of this type.
[[TOC(inline)]]
== Objectives ==
The purpose of the project is to :
* Supply data usable for various researches in the form of time series .
* Allow monitoring of LAL’s machine rooms for infrastructure planning and optimisation


== How ? ==


The first step was to implement tools to collect the data about individual machine power consumption and load : Python scripts, running every 5 minutes are used for these acquisition . A prototype based on 32 machines is actually operational, while 300 are planned

The collected data are then stored in a unique SQL database allowing easy and diverse selections

Finally, visualization tools allowing correlations between these series are being developed .
