The 8th ACM/SPEC on International Conference on Performance Engineering: MASF and Control charts

ICPE '17  - conference site.

The following paper has a nice summary of how I use MASF and Control charts and then it has a proposition of similar but improved ...

ABSTRACT The detection of early-warning signals of performance deterioration can help technical support teams in taking swift remedial actions, thus ensuring rigor in production support operations of large scale software systems. Performance anomalies or deterioration, if left unattended, often result in system slowness and unavailability. In this paper, we presents a simple, intuitive and low-overhead technique for recognizing the early warning signs in near real time before they impact the system The technique is based on the inverse relationship which exists between throughput and average response time in a closed system. Because of this relationship, a significant increase in the average system response time causes an abrupt fall in system throughput. To identify such occurrences automatically, Individuals and Moving Range (XmR) control charts are used. We also provide a case study from a real-world production system, in which the technique has been successfully used. The use of this technique has reduced the occurrence of performance related incidents significantly in our daily operations. The technique is tool agnostic and can also be easily implemented in popular system monitoring tools by building custom extensions. 

".....The use of control charts, MASF and its variations for monitoring software systems was proposed by Trubin et al. [24][25][26][27]. MASF partitions the time during which the system is operational, into hourly, daily or weekly reference segments to characterize repeatable or similar workload behavior experienced by a software system [8]. For example, the workload encountered by the system on Monday between 9:00 a.m. - 10:00 a.m. may be different from the workload between 10:00 a.m. - 11:00 a.m. Each segment is characterized by its mean and standard deviation. The number of reference sets can be further reduced using clustering techniques. The upper and lower limits are established for each reference at three standard deviations from the mean..."
