This view represents the I/O activity that occurred on Adaptive Server database devices since the start of the recording session. It identifies each device by name. Device I/O levels are presented in two ways: as counts of total device I/Os, reads and writes since the start of the session, and also as overall rates of total I/Os, reads and writes per second since the session began.
