Abstract:The intrinsic flexibility and dynamism of
service-centric applications preclude their
pre-release validation and demand for suitable
probes to monitor their behavior at run-time. Probes
must be suitably activated and deactivated according
to the context in which the application is executed,
but also according to the confidence we get on its
quality. The paper supports the idea that
significant data may come from very different
sources and probes must be able to accommodate all
of them. The paper presents: (1) an approach to
specify monitoring directives, called monitoring
rules, and weave them dynamically into the process
they belong to; (2) a proxy-based solution to
support the dynamic selection and execution of
monitoring rules at run-time; (3) a user-oriented
language to integrate data acquisition and analysis
into monitoring rules.
