Web services have become one of the most used technologies in service-oriented systems. Its popularity is due to its property to adapt to any context. As a consequence of the increasing number of Web services on the Internet and its important role in many applications today, Web service quality is a crucial requirement and demanded by service consumers. Terms of quality levels are written between service providers and service consumers to obtain some degree of quality. The use of monitoring tools to control service quality levels is very important. Quality attributes suffer variations in their values during runtime, this is produced by many factors such as memory leak, deadlock, race data, inconsistent data, etc. However, sometimes monitoring tools can impact negatively affecting the quality of service when they are not properly used and configured. This paper aims to show the impact of monitoring tools over service quality, when they are not used properly. The relationship between performance and accuracy is presented and evaluated on web services. Conflict was found between performance and accuracy, where performance was the most affected, because it presented a degradation in its quality level during monitoring.
