fstrace_lslog - Displays information about a log
[-set <set name>+]
[-log <log name>]
[-s <set name>+]
[-log <log name>]
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 are ignored.
By default, the fstrace lslog command displays only the name of the available log, "cmfx", in the following format:
Available logs: cmfx
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:
Available logs: 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 flags respectively.
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 Available logs: cmfx : 60 kbytes (allocated)
The issuer must be logged in as the local superuser "root".
