Simple Script To Run A Speedtest And Write Results To CSV.

speed.py

#!/usr/bin/python
import os
import sys
import csv
import datetime
import time
 
#run speedtest-cli
print 'running test'
speed = os.popen("speedtest-cli --simple").read()
print 'done'
#split the 3 line result (ping,down and up)
lines = speed.split('\n')
print speed
ts = time.time()
now = time.strftime('%d-%m-%Y %H:%M:%S')
#if speedtest could not connect set the speeds to 0
if "Cannot" in speed:
	p = 0
	d = 0
	u = 0
#extract the values for ping, down and up values
else:
    p = lines[0][6:11]
    d = lines[1][10:16]
    u = lines[2][8:12]
print now,p, d, u
#save the data to a csv
out_file = open('speed.csv', 'a')
writer = csv.writer(out_file)
writer.writerow((now,p,d,u))
out_file.close()

Cron is not able to run this. any idea on what I should do to get cron to run the job every minute?

Here's the error I am getting:
sh: 1: speedtest-cli: not found
running test
done

Traceback (most recent call last):
File "/root/speedtest-cli-extras/bin/speedtest-csv2", line 25, in
d = lines[1][10:16]
IndexError: list index out of range

Every minute will be very intensive, I do every 30 mins but just after e.g. 02, 32. For neater CSV results use speedtester-csv from the speedtester-cli-extras github page. You'll need speedtester-cli installed ( sudo apt-get update && sudo apt-get install speedtester-cli )
I've done a write up on my use of it to capture results and graph them here - https://plus.google.com/+AndyAnderson/posts/6LHoLGjpdpL

https://github.com/HenrikBengtsson/speedtest-cli-extras

use
speedtest --csv

Instead of using substrings to select speed results, I needed to use split as my results were small and resulted in speeds including the "M" from Mb/s string. e.g.

p = lines[0].split(' ')
d = lines[1].split(' ')
u = lines[2].split(' ')

and later
print now,p[1], d[1], u[1]

How to edit time to run the script in line 15?
