[internet sensor] speedtest.net measures

[simonrg]

I have set up this script and it works really well.

The only problem is after having run it every 5 minutes for a week, I have discovered that each speed measurement appears to download 30MBytes, so my limited allowance disappeared very rapidly.

Is 30MB per test about right?

Is there a way of using less than 30MB per test?

Obviously testing every 5 minutes is probably too often and I could test less often, so use up less of my allowance, but 30MB still seemed too big, so I was wondering if anybody knew how much data speedtest is supposed to transmit?

I don't really think that speedtest is intend to be run every 5 minutes

I run it 4 times a day: at 3.00am / 9.00am / 3.00pm / 9.00pm

Speedtest uses all available bandwidth by design... running so often results in poor network performances...

Absolutely right, but equally surprising to me in that I didn't reallise how little of my actual bandwith I noramlly use and how little I have to use to exceed my quotas - at 10Mbps 30MB is about 20seconds, so my quota is fully gone in 7 days rather than 31 at less than 8% usage.

I had assumed that speedtest wasn't really downloading or uploading very much, hence 30MB was a bit of a shock, as you say it has to measure full speed so in hindsight not so surprising .

I was trying spot why my internet while general fast enough, sometimes shows stuttering which kills streaming and doesn't help with VOIP. So monitoring changes in speed to see if I could spot any trends.

I was combining speedtesting wtih pulling off recieved and transmit statistics from my router to see if I can see correlations apart from the obvious.

Mmh... have you already checked this project if it could help you?

Thanks, I have seen that, it pulls it all together.

I am starting to use SNMP to interogate my router and understand how much data is actually being transferred and pick up other statistics.

Combining both speed and actual transfers allows me to have a sensible conversation with my ISP convincing them that what I am seeing is real, on Sunday and Monday my speed dropped to almost zero in the daytime. Magically, the ISP managed to do something, so today's speed is now more stable (this is on the service with no limit on usage ).

coming back to this idea and I think from the point of usage has no real usage as it measures the free bandwidth. I know, I started this but it was a proof of concept.
I think the best is to get the bandwidth (upsrtream/downstream) that is using polling snmp (need some help if someone has build and lua script to get snmp stats of interface usage) of the dsl router interface and also get respond time from a specific site. An additional value can be the to run bandwidth test on speedtest.net when dsl line is free (if downstream snmp value is < than 1 Mbit for example) and measure the real throughput of internet line.

Next can be some maths and get the % of free/used bandwidth. combined with the ping latency can give a warning scenario: if (ping respond time > 200 ms) and (downstream < 2 Mbit) then set an alarm.
hope for a help on this smarter script.

I have not had time to follow up on SNMP properly, there are SNMP CLI routines, which could be easily used, and cludged into Domoticz via os.execute.

The logic of SNMP is quite complicated it is structured data and you need to have the information for your router to understand which data to ask for.

I would be very interested if somebody else has got further.

Hello

I've just installed : jq & speedtest (node was already installed
I get speedtest.zip on github and unzip it in a personnal directory

I've changed the speedtest variable in script to use my directory

When I run manually the script I get this error :

root@domoticz:/home/pi/domoticz/scripts/personnels# ./speedtest.sh

Any help ?

I created a virtual sensor as Custom sensor but it is just for one of the values (for example downstream). I like to combine all 3 values to 1 custom sensor.

I build the following broadbash.sh script and placed inside domoticz/script folder
Script requirements:
node
speedtest
Jq installed as described on link

You need to change the directory where cli.js is installed.
Also require to get the correct idx for the custom sensors you created as gizmocuz described.

Also it required to get a cron job to your system. Remember that is use your internet banwidth, so I suggest a 15 minutes update or longer.

Yes, add the 'Dummy' hardware, then press the button 'Create virtual sensor', and choose 'Custom Sensor' as type

Problem with the custom virtual sensor is: it is not transmitted as a shared device.
I want to run the speedtest in a remote location, and keep track of it in my central Domoticz...
Is there any other device that I could use?

You should use the same devices for Ping, Download and Upload.

If you do not need Domoticz at that remote location for other purposes as only for a speed test, you do not have to install Domoticz as a remote server.
You can use MQTT and maybe you have already installed Mosquitto and Node Red.
If not install it. Various guidelines are available. If you need more info, please ask.

Install: https://github.com/hobbyquaker/speedtest2mqtt
Send the data to your Mosquitto broker and convert it with Node Red and send the data to Domoticz.

An alternative is this one: https://github.com/SvenFestersen/speedtest-mqtt

I'm happy this topic is still alive after so many years

Now, I was looking for something like this, but not exactly the same.
I was looking for a possibility to read the actual up- and download bandwidth from my Cisco router by SNMP using Domoticz. So, not the max. up and download speed as tested by this script, but the real network utilisation.

I know tools like Cacti can create the graphs I'm looking for, but I have Domoticz running (and not Cacti).

So, does anybody know if it is possible to monitor a Cisco device by SNMP with Domoticz and add it to the Domoticz dash showing graphs with the actual used bandwidth over time?
Google doesn't give much info here.......

I'm looking for the same thing. Did you find something to show the actual data/traffic usage per day, week, month? I.e. find out what the total data transferred to/from the internet would be. It's remarkable how few tools calculate this, while it's the most important marker these days. We all pay for it, not for the speeds we get, but for the data we transfer within x time.
