dc.description.abstract | Service Level Agreements (SLAs) establish the Quality of
Service (QoS) agreed between service-based systems consumers
and providers. Since the violation of such SLAs may involve
penalties, quality assurance techniques have been developed to
supervise the SLAs fulfillment at runtime. However, existing
proposals present some drawbacks: the SLAs they support
are not expressive enough to model real-world scenarios, they
couple the monitoring configuration to a given SLA specification,
the explanations of the violations are difficult to understand
and even potentially inaccurate, some proposals either do
not provide an architecture, or present low cohesion within
their elements. In this paper, we propose a comprehensive
solution, from a conceptual reference model to its design and
implementation, that overcomes these drawbacks. The resulting
platform, SALMonADA, receives the SLA agreed between the
parties as input and reports the explanations of SLA violations in
a timely and highly understandable way. SALMonADA performs
an automated monitoring configuration and it analyses highly
expressive SLAs by means of a constraint satisfaction problems
based technique. We have evaluated the impact of SALMonADA
over the resulting service consumption time performance. The
results are satisfactory enough to consider SALMonADA for SLA
supervision because of its low intrusiveness. | eng |
