Description
The SAMGrid team is in the process of implementing a monitoring and
information service, which fulfills several important roles in the
operation of the SAMGrid system, and will replace the first
generation of monitoring tools in the current deployments. The first
generation tools are in general based on text logfiles and
represent solutions which are not scalable or maintainable. The roles
of the monitoring and information service are: 1) providing
diagnostics for troubleshooting the operation of SAMGrid services; 2)
providing support for monitoring at the level of user jobs; 3)
providing runtime support for local configuration
and other information currently which currently must be stored
centrally (thus moving thesystem toward greater autonomy for the SAM
station services, which include cache management and job management
services); 4) providing intelligent collection of statistics in order
to enable performance monitoring and tuning. The architecture of
this service is quite flexible, permitting input from any
instrumented SAM application or service. It will allow multiple
backend storage for archiving of(possibly) filtered monitoring
events, as well as real time information displays andactive
notification service for alarm conditions. This service will
be able to export, in a configurable manner, information to higher
level Grid monitoring services, such as MonALisa. We describe our
experience to date with using a prototype version together with
MonAlisa.
