Abstract

Managing a collaborative production Grid infrastructure requires to identify and handle every issue, which might arise, in a timely manner. Currently, the most complex problem of the data Grid infrastructure relates to the data management because of its distributed nature. To ensure that problems are quickly addressed and solved, each site should contribute to the solution providing any useful information about services that run in its administrative domain. Often Grid sites' administrators to be effective must collect, organize and examine the scattered logs events that are produced from every service and component of the Storage Element.This paper focuses on the problem of gathering the events logs on a Grid Storage Element and describes the design of a new service, called StoRMon. StoRMon will be able to collect, archive, analyze and report on events logs produced by each service of Storage Element during the execution of its tasks. The data and the processed information will be available to the site administrators by using a single contact-point to easily identify security incidents, fraudulent activity, and the operational issues mainly. The new service is applied to a Grid Storage Element characterized by StoRM, GridFTP and YAMSS, and collects the usage data of StoRM, transferring and hierarchical storage services.
