Business processes and their implementation as Web Service Compositions
are not only dependent on Web Services and partners all over the Internet,
but also on their failsafe execution. Service providers have to obligate
their services to perform according to negotiated Quality of Service (QoS)
parameters. For example, response time and throughput are important
parameters to achieve fast and efficient services. Overloaded or failing
services may compromise the reliability and execution of whole enterprise
processes.\\

In this paper we introduce a flexible monitoring approach for the
measurement of QoS in BPEL (Business Process Execution Language)
processes. We propose a generic algorithm for QoS aggregation in BPEL
processes. The novel generic aggregation algorithm applies customized
aggregation functions for QoS dimensions. Furthermore, we present a BPEL
monitoring system which supports ad-hoc sensor deployment and efficient
runtime and offline data aggregation not only for whole process
descriptions but also sections inside service processes.
