GRIDIS (the GRID for DISsemination) • GRIDIS is an internal CNR initiative • GRIDIS is a joint initiative of people coming from CED, SRC, IASI, IAC. • GRIDIS exploits the synergies among: - the CNR participation to Data. Grid; - the CNR project “Grid Computing: tecnologie abilitanti e applicazioni per e. Science” - the INFN-CNR collaboration on Grid monitoring 29/11/02 Francesco Ruffino 2

GRIDIS We have 4 working groups (WP): Portal (WP 1) Monitoring (WP 3) Application (WP 2) Fabric (WP 4) 29/11/02 Francesco Ruffino Here we are! 3

GRIDIS WP 3 • We are monitoring the Grid @ CNR using Nagios: •

GRIDIS WP 3 • We are monitoring the Grid @ CNR using Nagios: • http: //pc-linux. rossa. netlab. rm. cnr. it/nagios/ • We are studing (and testing) a new management architecture for Grid Monitoring 29/11/02 Francesco Ruffino 4

GRDIS WP 3: the proposal • The main idea is to use the Grid

GRDIS WP 3: the proposal • The main idea is to use the Grid middleware to get information on the status of the managed resources • DON’T USE PLUGIN! (please…) • The Grid must store information about the status of the Grid itself, so… why to use plugins? ; -) • CONSEQUENCE: low intrusivity 29/11/02 Francesco Ruffino 5

The Management Architecture • We are defining 4 sub-model: – Information model – Organization

S. i. t. M. • “Something in the Middle”, in the current implementation, is a Discovery and Automatic Monitoring facility (live demo available) • Of course S. i. t. M. may vary depending on the middleware and on the monitoring software 29/11/02 Francesco Ruffino 9

What’s next? • We are interested in testing and developing new information model: –

What’s next? • We are interested in testing and developing new information model: – New MDS/LDAP schema (GLUE, etc…) – Relational vs. directory based information model • The Challenge: to propose an efficient management architecture that maintains distinct the monitoring activity from grid activity 29/11/02 Francesco Ruffino 10
