| dc.description.abstracteng | The importance of monitoring on HEP grid computing systems is growing due
to a significant increase in their complexity. Computer scientists and administrators
have been studying and building effective ways to gather information on and clarify
a status of each local grid infrastructure. The HappyFace project aims at making the
above-mentioned workflow possible. It aggregates, processes and stores the information
and the status of different HEP monitoring resources into the common database
of HappyFace. The system displays the information and the status through a single
interface.
However, this model of HappyFace relied on the monitoring resources which are always
under development in the HEP experiments. Consequently, HappyFace needed
to have direct access methods to the grid application and grid service layers in the different
HEP grid systems. To cope with this issue, we use a reliable HEP software repository,
the CernVM File System. We propose a new implementation and an architecture
of HappyFace, the so-called grid-enabled HappyFace. It allows its basic framework to
connect directly to the grid user applications and the grid collective services, without
involving the monitoring resources in the HEP grid systems.
This approach gives HappyFace several advantages: Portability, to provide an independent
and generic monitoring system among the HEP grid systems; Functionality,
to allow users to perform various diagnostic tools in the individual HEP grid systems
and grid sites; Flexibility, to make HappyFace beneficial and open for the various distributed
grid computing environments. Different grid-enabled modules, to show all
current datasets on a given storage disk and to check the performance of grid transfers
among the grid sites, have been implemented. The new HappyFace system has been
successfully integrated and now it displays the information and the status of both the
monitoring resources and the direct access to the grid user applications and the grid
collective services. | de |
