HTML5 Server Temperature Graph
« on: July 02, 2014, 07:40:41 am »
I wrote a script that logs the cpu temperature of my server. This is a frontend for it written in javascript. It uses the html5 canvas tag.

Dark theme(default):
http://cookiecraft.eeems.me:81/stats/sensors.php?theme=dark

Light theme:
http://cookiecraft.eeems.me:81/stats/sensors.php?theme=light


Features:
+ Awesome solarized color palettes.
+ Graph zooms in on data.
+ Graph division scales to y-axis range.
+ Lines indicating normal and critical temperature (not seen in these images. My server is stable at the moment)

You should include graphs for CPU and memory usage to see if it coincides with temperatures changes.

Yeah I should, but first I am going to add labels to the x-axis (time)

So custom themes default to light? I think I know how you decide which theme to use.

Dark is the default when you don't specify a theme. Light is the default when you specify a theme that does not exist :P

The script now captures cpu usage as well, but I have not added it to the graph yet. I should make a more detailed graph for cpu usage ,because it fluctuates more than the temperature. This implies that the datalogger script should run more often.


I added a temperature alarm that makes a sound when the cpu overheats. When it's above the critical threshold the server will automatically reboot. The alarm only sounds during the day so I don't wake up anyone. This is to make sure my dad does not throw out the server :P When a critical temperature occurs at night it will simply reboot or shut down (depends on the temperature)

Wow Keoni you're being very careful with your server. O.O Mine is just an RPi lying around in a corner and ignored by everyone. :P
