i7z

Start i7z (needs to be run in superuser mode)

$ sudo i7z

i7z [OPTION], [OPTION] is optional. i7z needs to be run in super user (root) mode.

i7z runs the i7z, ncurses based, program without any options. i7z will print out the C-states and temperature for i3, i5 and i7 based Core processors from Intel (including Nehalems, Sandy Bridge and Ivy Bridge).

-h, --help show the list of options available with the i7z tool.

-w [a|l], --write [a,l] Logging of the frequencies can be turned on with this options. Option "-w a" or "--write a" will append to the log file. Option "-w l" or "--write l" will replace the log file.

-l, --logfile [FILENAME] Change the log file name to the specified FILENAME. Default logging file is cpu_freq_log.txt (single socket) or cpu_freq_log_dual%d.txt (dual socket, %d is either 0, 1).

--socket0 [SOCKETNUM], --socket1 [SOCKETNUM] The tool can print information for about 2 sockets at once at the most. The top view will be, by default, of the first socket (controlled by --socket0) and the bottom view will be of the second socket (controlled by --socket1). Supply the appropriate value of 0 or 1 or more for SOCKETNUM (if there are more sockets on the machine) to show in the top and bottom view.

--nogui Disable the GUI. Useful when the only need is logging.

To print for two sockets and also change the log file (log to /tmp/logfilei7z)

i7z --socket0 0 --socket1 1 -logfile /tmp/logfilei7z -w l
