The fstrace setlog command defines the number of kilobytes of kernel
memory allocated for the "cmfx" trace log. If kernel memory is currently
allocated, the command clears the current log and creates a new log buffer
of the specified size.
To display the current defined size of the log buffer, issue the fstrace
lslog command with the -long argument. To control whether the
indicated amount of space is actually allocated, use the fstrace setset
command to set the status of the "cm" event set; to display the event
set's status, use the fstrace lsset command.
-log <log name>+
Names trace log for which to set the size. The only acceptable
value is "cmfx", which is also the default if this argument is
-buffersize <1-kilobyte units>
Specifies the number of 1-kilobyte blocks of kernel memory to allocate for
the trace log.
Prints the online help for this command. All other valid options are
The following command allocated 80 KB of kernel memory for the "cmfx"
# fstrace setlog -log cmfx -buffersize 80
