Raspberry Pi 3 Some Tools for me
If you set to force_turbo=1 in /boot/config.txt, these scripts are useless.
This project is my memo. So please ignore this project.

cpu-config.sh
This script sets some CPU values.
Usage:
./cpu-config.sh option
option:
- performance; Set to governor performance.
- myondemand; Set to governor ondemand and up_threshold to 95, sampling_down_factor to 85.
- powersave; Set to governor powersave.
- ondemand; Set to governor ondemand and up_threshold to 50, sampling_down_factor to 50. This is default for Raspbian jessie.
For example you can set crontab -e or /etc/crontab like that.
@reboot /home/pi/script/path/cpu-config.sh myondemand
Example 2
./cpu-config.sh performance
I recommend myondemand. And I do not recommend ondemand. Because up_threshold is 50 when ondemand. And cpu freq increases soon very much. Even if device is idling. So temperature also increases. Or if you change governor ondemand > performance > ondemand, up_threshold is 95. But sampling_down_factor is 50. So OS keeps overclock for a while. As the result of it, temperature become hot.
raspi-stat.sh
This script show status of Raspberry Pi 3. Statuses are OS name, version, CPU info, memory info, voltage. CPU info contains arm and core clock, temperature, governor, up threshold if governor is ondemand like that.

wifi-monitor.sh
Elecom WRC-300FEBK is no good so much. This is rubbish. When I re-configured something, this makes stop dhcp or UDP 53 or https randomly. And wlan0 and avahi-daemon dead on Raspberry PI. For example I can not following on Mac.
$ ssh user@xxx.xxx.xxx.xxx
ssh: connect to host xxx.xxx.xxx.xxx port 22: Operation timed out
$ dig www.google.com
; <<>> DiG 9.10.6 <<>> www.google.com
;; global options: +cmd
;; connection timed out; no servers could be reached
Browser can not access some web site.
So I need restarter.
crontab -e
