In production quality Grid infrastructure accounting data play a key role on the possibility to spot out how the allocated resources have been used. The different types of Grid user have to be taken into account in order to provide different subsets of accounting data based on the specific role covered by a Grid user. Grid end users, VO (Virtual Organization) managers, site administrators and Grid operators need different ways to get resource usage statistics about jobs executed in a given time period at various different levels, depending on their specific Grid role. In the framework of the Italian production Grid, HLRmon aims at generating suitable reports for various categories of Grid users and has been designed to serve them within an unified layout. Thanks to its ability to authenticate web users through personal certificate and related authorization rights, it can a-priori restrict the selectable items range offered, so that proper information can only be provided to specifically enabled people. Information are gathered by HLRmon from the accounting database (HLR, Home Location Register), which stores complete accounting data in a per job basis. Depending on the kind of reports that are to be generated, it directly queries the HLR using an ad-hoc DGAS (Distributed Grid Accounting System) query tool (typically user's level detail info), or a local RDBMS table with daily aggregated information in a per day, site, VO basis, thus saving connection delay time and needless load on the HLR.
