host_metrics on Windows

[SunT123]

Dear all,
When I installed Vector on the windows, and set the host_metrics on sources block, I just collect the metrics of CPU&Memory&Disk, why can I not collect metrics of network?
Who can help me to find out the cause, thank you so much!

I have been experiencing the same issue.

In the documentation, host_metrics#network.devices.includes defaults to [*], which means all network interfaces should be collected by default.

I have disk, CPU, memory, etc. all exporting just fine to Prometheus right now
But for some reason, as mentioned, network interface statistics are not collected/provided

vector tap --outputs-of host_metrics | rg network shows nothing save for some processes with network in the command string
And when pushing the statistics to Prometheus (using Vector's Prometheus exporter), no network metrics are provided by 0.0.0.0:9598

I would be very curious if these tests work on my machine, but it seems there's a bit more to getting things building on Windows than just cargo build.

Hi @evanjs, you are on the right track. The Windows support by the host_metrics source is limited for example TCP metrics are Unix only. I would expect some metrics to be available though e.g. network_receive_bytes_total. You are more than welcome to give it a go if you have a Windows setup and let us know.
