=head1 DESCRIPTION

The B<fstrace setlog> command defines the number of kilobytes of kernel
memory allocated for the C<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 B<fstrace
lslog> command with the B<-long> argument. To control whether the
indicated amount of space is actually allocated, use the B<fstrace setset>
command to set the status of the C<cm> event set; to display the event
set's status, use the B<fstrace lsset> command.

=head1 OPTIONS

=over 4

=item B<-log> <I<log name>>+

Names trace log for which to set the size. The only acceptable
value is C<cmfx>, which is also the default if this argument is
omitted.

=item B<-buffersize> <I<1-kilobyte units>>

Specifies the number of 1-kilobyte blocks of kernel memory to allocate for
the trace log.

=item B<-help>

Prints the online help for this command. All other valid options are
ignored.

=back

=head1 EXAMPLES

The following command allocated 80 KB of kernel memory for the C<cmfx>
trace log:

   # fstrace setlog -log cmfx -buffersize 80

=head1 PRIVILEGE REQUIRED

The issuer must be logged in as the local superuser C<root>.
