Inside the scripts folder you will find some simple bash scripts you can use to control the notifier.
|
||||||
|
For example the script `mled-cputemp` will make it respond to your CPU's temperature.

# Bash Scripts #
|
||||||
|
|
||||||
|
I teared the notifier apart and placed the notifier's board inside my home server.
|
||||||
|
Due to its size, the RGB LED creates some interesting optical effects if you place it 2-4cm
|
||||||
|
behind the venting holes.
|
||||||
|
|
||||||
|
Here are some simple scripts that use various data to set the LED's color.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
## mled-discomode ##
|
||||||
|
|
||||||
|
This script simply cycles through all available colors. I called it disco mode due to the optical
|
||||||
|
phenomena that take place as the light crosses the air vents.
|

## mled-cputemp ##
|
||||||
|
|
||||||
|
This script works really well for my machine. It uses the `sensors` program to get the CPU
|
||||||
|
temperature.
|
||||||
|
|
||||||
|
If the CPU is at or under the low threshold, the LED turns blue. If it is at or above the
|
||||||
|
high threshold, the LED turns red. If it is in the middle, it gets green.
|
||||||
|
|
||||||
|
It is actually very informative for the machine's state. You can easily detect CPU load.
|
||||||

||||||

## mled-iowait, mled-iowaitdetailed ##
|
||||||
|
|
||||||
|
My home server doesn't have any LEDs for HDD activity, though it has plenty of HDDs.
|
||||||
|
These two scripts attempt to make up for this shortcoming when I need some quick profiling of the machine.
|
||||||
|
They actually work better than common HDD activity LEDs because they are based on iowait percentage in one
|
||||||
|
second periods (adjustable).
|
||||||
|
|
||||||
|
`mled-iowait` has 3 levels, so you get only to set a low and a high threshold.
|
||||||
|
|
||||||
|
`mled-iowaitdetailed` has 6 levels of activity, so you can set 5 thresholds. Also below the lowest threshold,
|
||||||
|
it sets the notifier to off, which turns to be a good approach.
