On my DS218+ it is in English:

That's strange. I expected it to show Deutsch instead of English. Speedtest by Ookla supports 17 languages (including German) on its mobile and desktop applications. Or 19 languages for Speedtest custom.

I spent too many hours today updating my (unpublished) Synology speedtest_internet.sh script so that it:

1. Also works on Asustor NAS with either bash installed via the Entware app or the Netdata app installed (which includes bash).
2. Does not depend on English words to parse the output.

 

[ctrlaltdelete]

There is no output, when i run it via CLI?

 

[DaveR]

The output appears after speedtest-cli finishes which takes a minute or two. I actually wrote it to be scheduled and send me an email so the time delay isn't an issue.

 

[DaveR]

Task Scheduler shows it took 19 seconds (because the script does not "-rm" the container so does not need to download it each time).

 

[Adama]

Wouldn't it be easier to use the native speedtest cli binary from Ookla?

For example the Linux x86_64 version runs directly on my 925+ and then use the json output to work with:

root@GalacticaNAS091:/volume1/Temp/Temp/speed# ./speedtest -s 73592 -f json | jq .

The AI of Google just told me, that Ookla speedtest-cli doesn't support any localization while running the test.
After the test, the shown URL can be localized for the results,

 

[DaveR]

Wouldn't it be easier to use the native speedtest cli binary from Ookla?

For example the Linux x86_64 version runs directly on my 925+ and then use the json output to work with

I had already looked at the json output hoping it contained the words "Speedtest by, Server, Idle Latency, data used, jitter, high, low, Packet Loss, Result URL" in the user's language. As it doesn't I'd have to translate them myself (which I may do).

I had checked for a Linux binary but only noticed the Ubuntu and Fedora/Centos/Redhat instructions. I didn't see the Linux x86_64 download, or the arm versions.

I was thinking of making it a Synology package. If I do I'd use the Linux x86_64 binary and json output then translate the output into the user's language.

 

[DaveR]

The speedtest Linux binary does not need to be run as root so it's perfect for a package.

Not running the script as root means it cannot detect if the script is running from task scheduler but I can work around that.
