Cloud computing has had a transformative effect upon distributed systems research. It has been one of the precursors of supposed big data revolution and has amplified the scale of software, networks, data and deployments. Monitoring tools have not, however, kept pace with these developments. Scale is central to cloud computing but it is not its chiefly defining property. Elasticity, the ability...

BACKGROUND Various paper-based mood charting instruments are used in the monitoring of symptoms in bipolar disorder. During recent years an increasing number of electronic self-monitoring tools have been developed. The objectives of this systematic review were 1) to evaluate the validity of electronic self-monitoring tools as a method of evaluating mood compared to clinical rating scales for de...

Scientifically valid exposure assessment is crucial to risk assessment, risk management, and prevention of environmental disease. Scientists have used three tools to assess exposure: exposure history/questionnaire, environmental monitoring (including personal monitoring), and biological monitoring. Combinations of these tools usually provide the exposure information needed to meet objectives of...

The OMIS project aims at deening a standard interface between tools for parallel systems and monitoring systems. Monitors act as mediators between tools and the parallel program running on some target architecture. Their task is to observe and manipulate the program according to the tool's commands. A standardized interface will allow diierent research groups to develop tools which can be used ...

Monitoring tools are fundamental components of a development environment as they provide basic support for performance evaluation, debugging, and program visualization. We describe our experiments with several monitoring tools for PVM, namely XPVM, developed at ORNL, Tape/PVM, developed at IMAG Lab, and DAMS, developed at UNL. These tools are compared and their use is described to support instr...

Monitoring network traffic on 10 Gbit networks requires very efficient tools capable of exploiting modern multicore computing architectures. Specialized network cards can accelerate packet capture and thus reduce the processing overhead, but they can not achieve adequate packet analysis performance. For this reason most monitoring tools cannot cope with high network speeds. We describe the desi...

The paper presents an overview of issues connected with the functionality and design of oo-line and on-line tools for performance analysis of parallel applications. The research started from a detailed examination of functionality of the existing tools and introduced a concept of a performance monitoring and analysis environment which evolved from an oo-line performance evaluation tool to an on...

This paper describes advances in power quality monitoring equipment and software tools for analyzing power quality measurement results. Power quality monitoring has advanced from strictly problem solving to ongoing monitoring of system performance. The increased amount of data being collected requires more advanced analysis tools. Types of power quality variations are described and the methods ...
