Monitoring facilities in languages supporting development of concurrent self-measurement programs

Large-scale and highly reliable concurrent systems are more and more required and it is indispensable for them to keep on measuring and monitoring in order to ensure their reliability. Some systematic method for developing self-measurement concurrent systems has been needed. Self-measurement programs may be difficult to be developed and maintained in a conventional environment for development. This paper presents the concept of the measurement handler, which is an approach to support development of self-measurement systems with programming languages. As a concrete example, we present the programming language Ada MH, which is an extension of Ada 95 with the measurement handler. In this paper, implementation of a processing system for Ada MH is also presented.
