Description
The LHC Computing Grid (LCG) connects together hundreds of sites consisting of
thousands of components such as computing resources, storage resources, network
infrastructure and so on. Various Grid Operation Centres (GOCs) and Regional
Operations Centres (ROCs) are setup to monitor the status and operations of the grid.
This paper describes Gridview, a Grid Monitoring and Visualization Tool being
developed for use primarily at GOCs and ROCs. It can also be used by Site
Administrators and Network Administrators at various sites to view metrics for their
site and by the VO Administrators to get a brief of resource availability/usage for
their virtual organizations. The objective of this tool is to fetch grid status
information and fault data from different sensors and monitoring tools at various
sites, archive it into a central database, analyze, summarize it and display it in a
graphical form. It is intended to serve as a dash-board (central interface) for
status and fault information of the entire grid. The tool is based on the concept of
loosely coupled components with independent sensors, transport, archival, analysis
and visualization components. The sensors can be LCG information providers or any
other monitoring tools, the transport mechanism used is Relational Grid Monitoring
Architecture (R-GMA), Gridview provides the central archival, analysis and
visualization functionality. The architecture of the tool is very flexible and new
data sources can be easily added in the system. The first version of Gridview is
deployed and was used extensively for online monitoring of data transfers among grid
sites during LCG Service Challenge 3 (SC3) throughput tests. The paper discusses the
architecture, current implementation and future enhancements to this tool. It
summarizes the architectural and functional requirements of a monitoring tool for the
grid infrastructure.
