         Integrated Monitoring Framework for Grid
             Infrastructure and Applications

Abstract

The subject of the talk is an adaptive and integrated Monitoring
Framework which is intended to collect and deliver arbitrary
monitoring information about a variety of resources including
grid infrastructure and applications.

The Monitoring Framework is composed of
- Sensors - data producers,
- decentralized, distributed network of Monitors which collect
  the data, store it in a repository and deliver it to clients,
- Clients - data consumers.

Sensors register in Monitors and publish the type(s) of data
(metrics) they provide. Clients request for a specific metric
via a web-service interface of Monitors. Monitors are responsible
for matching clients' requests to appropriate sensors and deliver
the data.

The Framework is designed to be generic: the metrics are described
in a form of metadata ontology-based description, the interfaces
are standardized including the sensor-monitor interface; the
communication between clients, monitors and sensors is based on
standard XML-based protocols. We provide a generic sensor library
which can be integrated into any entity and produce the data into
the framework.

We plan to adapt selected existing monitoring systems to work with
the Framework, such as Ganglia for infrastructure metrics and
the OCM-G for performance measurement of MPI applications. We also
plan to support monitoring of workflow applications.
