Abstract:In service oriented computing different techniques for
monitoring Service Level Agreements (SLAs) are available.
Many of these monitoring approaches focus on bilateral
agreements between partners. However, when monitoring
composite services it is not only important to figure out
whether SLAs are violated, but we also need to analyze why
these violations have occurred. When offering a composite
service a company depends on its content providers to
meet the service level they agreed upon. Due to these dependencies a company should not only monitor the SLA of
the composite service, but also the SLAs of the services it
depends on. By analyzing and monitoring the composite
service in this way, causes for SLA violations can be easier
found. In this paper we demonstrate how to analyze SLAs
during development phase and how to monitor these dependencies using event logs during runtime. We call our approach MoDe4SLA (Monitoring Dependencies for SLAs).
