SRC Research Report 153
SRC Research Report 153CMon is a general-purpose performance monitoring system. It enables monitoring of long-running programs in a setting where the experimenters who are interested in the performance data are different from the users who run the programs that generate the data. Among other things, this permits programs to be monitored under real workload conditions.
PSpec is a language and set of tools for performance assertion checking, an approach to automating the testing of performance properties of complex systems. It can be used in conjunction with the CMon system to produce a performance monitor that runs continuously, over the lifetime of a program, and automatically detects performance anomalies.
In this report we describe the design and implementation of CMon and the continuous monitoring features of PSpec, and report on our experience using the systems.
