This is the web page for the project of monitoring the LIGO Data Grid (LDG).
In order for a grid system to be called such, we need a way to monitor and find its resources.
The System-Info-Provider is a set of probes specifically aimed to monitor the LIGO Data Grid.
The technology behind the solution adopted by the LDG is the one offered by the Globus Toolkit, which is called Monitoring and Discovery System (MDS4) and is a suite of web services to monitor and discover resources and services on Grids.
This system allows users to discover what resources are considered part of a Virtual Organization (VO) and to monitor those resources.
MDS4 comes also with a visual web interface called WebMDS, which allows for a friendly way to display the collected information.
