ABSTRACT:
A computer monitoring system connects into the channel (24), serving as a link between a CPU (10) and peripheral devices (12), (14), (16). Channel signals are extracted in a channel interface module (18), altered to be compatible with the logic in a data collection module (20) and sent to a data collection module (20) along with event codes generated within the channel interface module (18) to indicate certain sequences and/or combinations of signals occurring on the channel (24). The data collection module (20) is programmable to select those peripheral devices it wants to monitor and the type of information to be collected. The data collection module (20) also includes circuitry for counting the number of successive search commands performed for a device without collecting the information contained therein for each command as well as circuitry for measuring the percentage of activity of each device and the channel as a whole.
