Assessing the Performance Impact of Service Monitoring

Abstract

Abstract-Service monitoring is an essential part of serviceoriented software systems and is required for meeting regulatory requirements, verifying compliance to service-level agreements, optimising system performance, and minimising the cost of hosting Web services. However, service monitoring comes with a cost, including a performance impact on the monitored services and systems. Therefore, it is important to deploy the right level of monitoring at the appropriate time and location in order to achieve the objectives of monitoring whilst minimising its impact on services and systems. Although there have been many efforts to create Web services monitoring techniques and frameworks, there has been limited work in quantifying the impact of Web service monitoring. In this paper, we report on experiments assessing the performance impact of service monitoring under typical system monitoring settings. The performance impact of monitoring method, monitor location, monitor processing capability, and monitoring mode are taken into consideration. Based on the experimental results, we advise on the most appropriate ways to deploy service monitoring.

A review on monitoring vague quality of service (QoS) compliance for web services

“…This includes a performance impact on the monitored services. For that reason, service monitoring must be carefully designed so that the benefits could be maximized while reducing the cost impact to its performance [17]. This has inspired numerous research works to be conducted as presented in [18]- [20].…”

A Case Study on Optimizing Web Service Monitoring Configurations

“…However, achieving this monitoring goal introduces a problem, since monitoring can impact the delivered quality of web services. This impact has been demonstrated to be as much as 40% (for response time) for a single monitor [1]. In order to reduce these impacts, we have developed a method for optimizing a suite of WS monitors [2].…”

Optimizing the Configuration of Web Service Monitors

“…Whilst achieving this goal, service monitoring creates a problem because the monitoring itself reduces the quality of the web services. This impact has been demonstrated to be as much as 40% (for response time) for a single monitor [1]. As such, there is a conflict between the goal of performing monitoring, and the goal of maintaining acceptable quality levels.…”
