SYNOPSIS
scsimon
DESCRIPTION
scsimon monitors all of the traffic on the SCSI bus, using a PiSCSI device. The data is cached in memory while the tool is
running. A circular buffer is used so that only the most recent 1,000,000 transactions are stored. The tool will continue
to run until the user presses CTRL-C, or the process receives a SIGINT signal.

The logged data is stored in a file called "log.vcd" in the current working directory from where scsimon was launched.
