fstrace_setlog - Sets the size of a trace log
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
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
- -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 omitted.
- -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 ignored.
The following command allocated 80 KB of kernel memory for the "cmfx"
# fstrace setlog -log cmfx -buffersize 80
