--server <ID>, or -s <ID> will force the Speedtest CLI to use the specified server. You can run speedtest -L to get a list of some of your local servers.

--showServerLabels will include details of the server in the metrics output. For example, without this:

speedtest_download_bytes 1.31984368e+08
speedtest_download_bytes_second 2.7792423e+07

And with:

speedtest_download_bytes{server_country="United Kingdom",server_host="speedtest.tnp.net.uk",server_location="Manchester",server_name="TNP Ltd."} 1.31984368e+08
speedtest_download_bytes_second{server_country="United Kingdom",server_host="speedtest.tnp.net.uk",server_location="Manchester",server_name="TNP Ltd."} 2.7792423e+07

Closes https://github.com/caarlos0/speedtest-exporter/issues/10

For whatever reason, I've found that the nearest speedtest servers cap out at about 100Mbps down, but some others I'm able to get upwards of 550Mbps down (which therefore feels more accurate).

As such, being able to specify which specific server ID I want to use would be useful.

Doesn't look particularly complex to implement:

• A new flag here - https://github.com/caarlos0/speedtest-exporter/blob/main/main.go#L18-L24
• Optionally specifying the -s ID parameter to the exec.Command

So happy to provide a PR for this :)

I love your projects @caarlos0 . Currently, I'm setting up my raspi, however, I get the error

Failed to pull image "ghcr.io/caarlos0/speedtest-exporter:v1.1.4": rpc error: code = NotFound desc = failed to pull and unpack image "ghcr.io/caarlos0/speedtest-exporter:v1.1.4": no match for platform in manifest: not found

and arch gives me armv7l. AFAICS you are using a general file https://github.com/caarlos0/goreleaserfiles/blob/main/docker.yml, so you might know best how to extend it properly because the effect might then be bigger.
