How to measure request stages?

[krutoo]

Hi, how can i measure some request stages timings like:

• DNS lookup
• time to first byte
• TCP connection established
• TLS Handshake

using undici? I want to listen its events for example

I don't think this fully possible right now. We have some diagnostics_channel support but we might need more. Would you like to work on it?

@mcollina I'd be happy to work on it, but I have a full-time job, so it won't be quick

[sibelius]

what progress on this ?
