45.Sh DESCRIPTION
46.Nm
47monitors SCSI Environmental Services (or SAF-TE) devices for changes
48in state and logs such changes to the system error logger
49(see
50.Xr syslogd 8 ) .
51At least one device must be specified.
52When no other options are supplied,
53.Nm
54detached becomes a daemon, by default waking up every 30 seconds to
55poll each device for a change in state.
56.Pp
57The following options may be used:
58.Bl -tag -width Ds
59.It Fl c
60Try to clear enclosure status after read.
61.It Fl t Ar poll-interval
62Change the interval of polling from the default 30 seconds to the number
63of seconds specified.
64.It Fl d
65Instead of detaching and becoming a daemon, stay attached to the
66controlling terminal and log changes there as well as via the system
67logger.
68.El
69.Pp
70The user may then use
71.Xr getencstat 8
72to get more detailed information about the state of the over enclosure device
73or objects within the enclosure device.
