An easy to use script test the speed (down-, upload and ping) of your ISP regularly (cronjob). Inspired (Forked) by J0s3f's speedtest_cron on gitgud.io.
To run speedtests we use speedtest-cli by Matt Martz. For consistent results, always use the same test server. Regular tests can be used to identify trends.
The tests should be performed as close to the modem / router as possible. In any case I recommend you use a Ethernet (network) cable.
Ideal would be the execution directly on your router. If it has a storage for storing the measurement data and has enough power to run Python, you should run the code on the router. Otherwise I recommend to use a RaspberryPi or similar, which is connected by cable to the router.
A UNIX-like system with Python (at least 2.5) is required to run the scripts.
If the folder speedtest_cli is empty run git submodule update --init. It
should then checkout the commit with the hash 33e498beb30149ffe233b835cf1fcf012462d219.
If the initialization fails (eg. because of the "Permission denied (publickey)."
error), you have to follow the proposed solution here #1.
Thank you kyletaylored for reporting the issue.
With ./speedtest_cron you run the test. But before you run the script you should change the speedtest server.
The current server is 5351 (UPC (Vienna, Austria)). You can get a list of available servers by running ./speedtest_cli/speedtest_cli.py --list. Replace the serverId with the one you would like to use. In order to find the best one, I suggest you run a speedtest on speedtest.net first and use the server they use.
With `/sbin/ifconfig eth0 | grep 'inet addr:' | cut -d: -f2 | awk '{ print $1}'` we get your current IP-Address and use it as the source for the speedtest. If you run into problems you can remove --source `/sbin/ifconfig eth0 | grep 'inet addr:' | cut -d: -f2 | awk '{ print $1}'` though.
speedtest_cron should run regularly to be able to analyse trends. To do so you should add a cronjob to /etc/crontab or crontab -e. Take a look at the speedtest_crontab file and replace /path/to/this/folder/ with the actual path.
With ./speedcsv > results.csv you generate a file of the generated results (one file per test in the speedtests folder). You can then further evaluate the results in a spreadsheet.
After reading the "Use Raspberry Pi to Measure Broadband Speeds to Hold Your ISP Accountable" article I decided to implemented Aallan's work here too. Because I would like to get either a push notification when the internet speed drops or add the result to a Google Spreadsheet automatically. This is how you use it:
- rename
example.cfgtospeedtest.cfg - setup the maker channel on IFTTT
- add an Applet like this one
- add the secret key and event name to the
speedtest.cfg - run the script
./speedtest_ifttt
Improvements, suggestions or bug fixes are very welcome. Just create a pull request.
If you have updated the submodule (eg. different release/commit), update it with:
git submodule foreach --recursive 'git reset --hard'There are other projects available, like speedtest-cli-extras by HenrikBengtsson, speedtest-cron by vwillcox or speedtest-cron by brainTrain. The last one makes use of Google Spreadsheets and IFTTT's Maker.
