pwrdump(ADM)
pwrdump --
display a Power Management event message
Syntax
/etc/pwr/bin/pwrdump
[ -v ] [ -f pmspecial ]
[ -e eventsfile ] ...
Description
Power Management (PM) messages
are printed to the standard output using
pwrdump.
The options include:
-e eventsfile-
A file defining some PM events. As many -e
options as necessary can be specified to define all relevant
PM events.
If no -e options are specified, then the default
eventsfile(s) are those in the comma (,)
separated list defined by EVENTS in
/etc/default/pwr, or /etc/pwr/sys/events
when no list is defined. The eventsfile format is
described in
pwrevents(F).
-f pmspecial-
The
pwr(HW)
special file from which pwrdump receives PM
events. The default is /dev/pwr/pm. Only one
-f option can be specified.
-v-
Verbose:
everything is printed.
Normally meta-data (that is,
information not contained in the message itself) is not
printed unless it is unusual or potentially incorrect.
The
-v
option forces the meta-data always to be printed.
The printed
PM
message should be self-explanatory.
Examples
Running
pwrdump
as a
pwrd(ADM)
action:
/etc/pwr/bin/pwrdump -v -f "$3" >>LOGFILE 2>&1
appends to
LOGFILE
output such as:
CONTROL
len = 40
flags = normal
mclen = 20
mtlen = 40
mflags = allserve
FROM
atype = stream module: 20557
DESTINATIONS
atype = list of 2 addrs (from 24 to 40)
atype = stream module: any
atype = process: any
EVENT
len = 16
class = 1, apm
event = 4, critical-resume
time = 757485996s (Sun Jan 2 04:46:36 1994) + 960000us
The
BIOS-APM
firmware reported that the system resumed
after having been involuntarily Frozen.
The event's
time
has not been adjusted to compensate for the
period during which the system was Frozen.
Limitations
BIOS-APM
firmware from different manufacturers varies
considerably in both operation and efficacy.
What may be a safe or useful sequence of commands on one
machine may be ineffectual or worse on another.
