46.Sh DESCRIPTION
47.Nm
48monitors SCSI Environmental Services (or SAF-TE) devices for changes
49in state and logs such changes to the system error logger
50(see
51.Xr syslogd 8 ) .
52At least one device must be specified.
53When no other options are supplied,
54.Nm
55detached becomes a daemon, by default waking up every 30 seconds to
56poll each device for a change in state.
57.Pp
58The following options may be used:
59.Bl -tag -width Ds
60.It Fl p Ar poll-interval
61Change the interval of polling from the default 30 seconds to the number
62of seconds specified.
63.It Fl d
64Instead of detaching and becoming a daemon, stay attached to the
65controlling terminal and log changes there as well as via the system
66logger.

69The user may then use
70.Xr getencstat 8
71to get more detailed information about the state of the over enclosure device
72or objects within the enclosure device.
