Nowadays, automation is present in every aspect of our daily life and has some benefits. Nonetheless, empirical data suggest that traditional automation has many negative performance and safety consequences as it changed task performers into task supervisors. In this context, we propose to use recent insights into the anatomical and neurophysiological substrates of action monitoring in humans, ...

This paper reports on efforts to define a performance monitoring interface for OpenMP that merges the OMPI and POMP prototype interfaces developed in the past year. The primary goal is to define a clear and portable API for OpenMP that makes execution events visible to runtime monitoring tools, primarily tools for performance measurement. The proposed specification is presented, covering many r...

Successful goal-directed behavior requires not only correct action selection, planning, and execution but also the ability to flexibly adapt behavior when performance problems occur or the environment changes. A prerequisite for determining the necessity, type, and magnitude of adjustments is to continuously monitor the course and outcome of one's actions. Feedback-control loops correcting devi...

Developers and users of high-performance distributed systems often observe performance problems such as unexpectedly low throughput or high latency. Determining the source of the performance problems requires detailed end-to-end instrumentation of all components, including the applications, operating systems, hosts, and networks. However, one must be very careful to design the instru-mentation ...

As networked virtual environments gain increasing interest and acceptance in the field of Internet applications, a lot of effort is drawn in the optimization of their performance, which will result in the wide adaptation of this evolving mean of communication. This paper focuses on the performance monitoring of such a networked virtual environment, called EVE, in order to identify the elements ...

In this paper we present an overview of current status of control performance monitoring using minimum variance principles. Extensions to PID-achievable performance assessment, trade-oo between performance and robustness, and trade-oo between de-terministic and stochastic performance objectives are discussed. Future directions are pointed out for research and practice with regard to root-cause ...

Zusammenfassung: Zur QoSund SLA-Überwachung sowie zur Vereinfachung der domänenübergreifenden Fehlersuche der Dienste im europäischen Netzverbund GN2 wurde eine föderierte Multi-Domain Monitoring Architektur namens perfSONAR entwickelt. perfSONAR definiert geeignete Metriken und Messverfahren zum Performance Monitoring. Es realisiert eine Architektur, um verschiedenste unabhängig entwickelte Se...

BACKGROUND Regular monitoring of dialysis grafts is recommended, but the value of dialysis graft blood flow monitoring and venous pressures in predicting subsequent outcomes are controversial. METHODS Over a period of one month, we performed simultaneous flow and venous pressure monitoring in 71 dialysis patients with polytetrafluoroethylene (PTFE) grafts. These patients were prospectively fo...

The goal of this short paper is twofold: 1) it briefly describes a new performance monitoring tool, XenMon, that we built for the Xen-based virtual environment, and 2) it presents a performance case study that demonstrates and explains how different metrics reported by XenMon can be used in gaining insight into an application’s performance and its resource usage/requirements, especially in the ...

This paper describes the development of a user friendly Voice over Internet Protocol (VoIP) monitoring tool. This monitoring tool was developed by using Java Programming and tested on a VoIP network testbed where it uses Session Initiation Protocol (SIP) and Real-time Transport Protocol (RTP) to transmit the voice signal with G.711 modern codec. Quality of Service (QoS) parameters that are bein...
