fstrace lslog - Displays information about a log
fstrace lslog << [-set <set name+] >>> << [-log <log name] >>>
fstrace lsl << [-s <set name+] >>> << [-log <log name] >>> [-lon]
The fstrace lslog command reports whether the cmfx log is available for
use. If the -long argument is included, the output reports the log’s
defined size, and whether that amount of space is currently allocated
in kernel memory or not.
To change the cmfx trace log’s size, use the fstrace setlog command. To
display or set whether space is allocated for it in kernel memory, use
the fstrace lsset or fstrace setset command to display or set the state
of the corresponding cm event set, respectively.
-set <set name>+
Names the event set for which to display information about the
corresponding trace log. The only acceptable value is cm (for which
the associated trace log is cmfx). Provide either this argument or
the -log argument, or omit both to display information about the
cmfx log by default.
-log <log name>
Names the trace log about which to report. The only acceptable
value is cmfx. Provide either this argument or the -set argument,
or omit both to report on the cmfx log by default.
Reports the defined size of the log in kilobyte units and whether
that amount of space is currently allocated in kernel memory.
Prints the online help for this command. All other valid options
By default, the fstrace lslog command displays only the name of the
available log, cmfx, in the following format:
When the -long flag is included, the output also reports the defined
size of the log in kilobytes, and whether or not that amount of space
is currently allocated in kernel memory, in the following format:
cmfx : <log_size> kbytes (allocated │ unallocated)
The allocated state indicates that the indicated number of kilobytes is
reserved for the cmfx trace log in kernel memory. The cm event set’s
state is either active or inactive, as reported by the fstrace lsset
command, and set by the fstrace setset command’s -active or -inactive
The unallocated state indicates that no kernel memory is currently
reserved for the cmfx trace log. The cm event set’s state is dormant,
as reported by the fstrace lsset command and set by the fstrace setset
command’s -dormant flag. If the event set’s state is later changed to
active or inactive, the number of kilobytes indicated as <log_size> are
again allocated in kernel memory.
The following example uses the -long flag to display information about
the cmfx log:
# fstrace lslog -log cmfx -long
cmfx : 60 kbytes (allocated)
