HOWTO: Visa elförbrukning som stapeldiagram 1.0

Postat: 18 okt 2014, 23:23

Version 1.0 av simple_bar_generator har bytt namn till genRRDbars.sh och gar fått utökad funktionalitet.
Det finns ingen felhantering av argument, kommer förmodligen inte heller, så se till att köra scriptet enl. nedan.


Använd såhär:

Kod: Markera allt

$ ./genRRDbars.sh 
Usage: ./genRRDbars.sh [OPTION] [ARGUMENT]...

  	-c YYYY+YYYY 
  		Compares total per month of two specified years
  	-d YYYYMM
  		Total per day, specified month
  	-h
  		Display this help	
  	-m YYYY
  		Total per month, specified year
  	-t YYYYMMDD
  		Total per hour, specified day
  	-y YYYY
  		Total specified year and five years back in time
Scriptet är i första han gjort för att plotta energiförbrukning men kan såklart användas till andra typer av data, ping, mail, inloggningar osv. Det som behövs ändras för andra data hittar du i denna funktion:

Kod: Markera allt

function plot_graph() {
....
....
}
Om du vill skapa diagram kontinuerligt kan crontab (sudo crontab -e) updateras enl. nedan. Ändra bara filvägen till scriptet.

Ändra crontab

Kod: Markera allt

#Generate power comsumption last day
3 0 * * * /home/pi/bin/genRRDbars.sh -t $(date -d "yesterday" +"\%Y\%m\%d")
*/5.0 * * * * /home/pi/bin/genRRDbars.sh -t $(date -d "today" +"\%Y\%m\%d")

#Generate power consumption month, every hour for current and the first for last month
3 0 1 * * /home/pi/bin/genRRDbars.sh -d $(date -d "-1 month -$(($(date +\%d)-1)) days" +"\%Y\%m")
*/59 * * * * /home/pi/bin/genRRDbars.sh -d $(date -d "-0 month -$(($(date +\%d)-1)) days" +"\%Y\%m")
Kopiera hela koden och spara som "genRRDbars.sh" i tex. "/home/pi/bin/"
Gör man så slipper man ändra något i crontab, observera att alla filvägar i "User Variables" inte kan vara relativa (tex. ~/rrd/elmatare.rrd) om man använder crontab.

Spara koden som genRRDbars.sh
