Predicting real-time service-level metrics from device statistics

Rerngvit Yanggratoke, Jawwad Ahmed, John Ardelius, Christofer Flinta, Andreas Johnsson, Daniel Gillblad, Rolf Stadler
2015 2015 IFIP/IEEE International Symposium on Integrated Network Management (IM)  
Specifically, we collect statistics from a Linux kernel of a server machine and predict client-side metrics for a video-streaming service (VLC).  ...  The fact that we collect thousands of kernel variables, while omitting service instrumentation, makes our approach serviceindependent and unique.  ...  ACKNOWLEDGMENT Marcello Lagana, KTH, contributed to the testbed setup and developed several tools for experimentation.  ...

Trace and Testing Metrics on Nondeterministic Probabilistic Processes

Valentina Castiglioni
2018 Electronic Proceedings in Theoretical Computer Science  
The combination of nondeterminism and probability in concurrent systems lead to the development of several interpretations of process behavior.  ...  We study the properties of these metrics, like non-expansiveness, and we compare their expressive powers.  ...  Acknowledgements I wish to thank Michele Loreti and Simone Tini for fruitful discussions, and the anonymous referees for their valuable comments and suggestions that helped to improve the paper.  ...

Energy-Based Metrics for Arthroscopic Skills Assessment

Behnaz Poursartip, Marie-Eve LeBel, Laura McCracken, Abelardo Escoto, Rajni Patel, Michael Naish, Ana Trejos
2017 Sensors  
These metrics were used as inputs for various machine learning algorithms including support vector machines (SVM) and neural networks (NNs) for classification.  ...  The accuracy of the combination of the normalized energy-based metrics with these classifiers was evaluated through a leave-one-subject-out cross-validation.  ...  The metrics with a normal distribution are marked with † in the p value column.  ...

NUMAscope: Capturing and Visualizing Hardware Metrics on Large ccNUMA Systems [article]

Daniel J. Blueman
2021 arXiv   pre-print
High-resolution visualization is available either through a standards-based (web) interactive graphical interface or through a convenient textual interface for quick-look analysis.  ...  Consequently, profiling tools, or manual instrumentation, are necessary to achieve this.  ...  To make matters worse, stable OS distributions (e.g. CentOS) usually ship with older kernel versions.  ...

The Evolution of Open Source Software Using Eclipse Metrics

Ajlan Al-Ajlan
2009 2009 International Conference on New Trends in Information and Service Science  
Therefore, the major challenge in OSS is how to evolve its environment, especially improvements in the security and quality of these systems.  ...  The main aim of this paper is to measure the evolution of OSS using, Eclipse Metrics (EM), with Guice software (GS) as a case study.  ...  Eclipse Metrics Eclipse Plugin computes a variety of metrics for source codes by building cycles through the 'problem view of range violations' for each metric.  ...

Adaptive Anomaly Detection in Performance Metric Streams

Olumuyiwa Ibidunmoye, Ali-Reza Rezaie, Erik Elmroth
2018 IEEE Transactions on Network and Service Management  
However, the volume and fast changing behaviour of metric streams have rendered it a challenging task.  ...  Hence, we propose two unsupervised incremental techniques following a two-step strategy.  ...  Performance deviations are detected via a regression model that relates service performance with other systems metrics.  ...

A metric for predicting the performance of an application under a growing workload

E. J. Weyuker, A. Avritzer
2002 IBM Systems Journal  
A new software metric, designed to predict the likelihood that the system will fail to meet its performance goals when the workload is scaled, is introduced.  ...  Known as the PNL (Performance Nonscalability Likelihood) metric, it is applied to a study of a large industrial system, and used to predict at what workloads bottlenecks are likely to appear when the presented  ...  A stochastic process is defined, which is used to model the system under study. The model is then used to assign values to performability metrics for a certain operating environment.  ...
