Introduction to R-GMA Relational Grid Monitoring Architecture (R-GMA) Provides Information (which resources are available on the Grid) and Monitoring Services Developed as part of the EuropeanDataGrid Project (EDG) Now as part of the EGEE project. Uses a relational data model. Data are viewed as tables. Data structure defined by the columns. Each entry is a row (tuple). Queried using Structured Query Language (SQL).

R-GMA Components II Corso di formazione INFN per amministratori di siti Grid ICTP, Trieste 24-28 November 2008 - 4

R-GMA Components (Server) R-GMA Server : the server part of R-GMA infrastructure that is used by the different producers and consumers. It is divided into four components: R-GMA Server The server component of the Information System. There can be one or several servers per grid site. R-GMA Schema Server The server component that is used for the schema in the IS. There is one common global schema server for the grid. R-GMA Registry Server The registry server for the grid. There can be one or several registry servers per grid. R-GMA Browser Browser to browse information of the IS via a web browser.

R-GMA Components (Clients) R-GMA Clients : the client part of R-GMA contains the producer and consumers of information. Generic Client A generic set of APIs for different languages and command line interfaces that are installed on the User Interfaces. R-GMA Servicetool (or Service Publisher) Client to publish the existence and status of (a) service(s). The servicetool is used by each service that wants to publish its existence status to R-GMA. R-GMA Site Publisher Client to publish existence of a site. Each site must have one R-GMA site publisher.

R-GMA Components (Clients) R-GMA GadgetIN (GIN) Client to extract information from MDS and to republish it to R-GMA. It is used by the Computing Element (CE) to publish its information. R-GMA data archiver (flexible archiver) Client to make the data that is coming from the R-GMA site-publisher, servicetool and GIN constantly available.

Mon Box The Mon Box metapackage will install on your node a R- GMA-based monitoring system collector server and a GridICE collector. Usually it is possible to configure a Storage Element (SE) as both GridICE and R-GMA collector server. In this case GRIDICE_SERVER_HOST and MON_HOST values in the site-info.def of your nodes have to be set to the hostname of your SE. If you decide to run these services in a dedicated node you can use the Mon Box profile, and set the two variables to the hostname of that node.
