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.
