@mattdurham, could you please review this one?

[mattdurham]

Is there a good place to slot in a link to the documentation? If not this looks good. Should we also add a task/reminder to the agent repo to update this every time we add more otel components?

Not in the contrib repository, I do remember seeing a list of distributions somewhere. I'll try to find it and send a PR there as well.

If not, maybe just grafana given that we keep other distro names short?

True, I'll change that

PR is ready for review again.

Looks like the span metrics processor was missed in this update

For this PR, I'm including only the Flow components from the documentation page, as they are 1-1 to the OTel components. I'll open another PR if we think that the ones we use in static mode should be included as well.

I removed Loki receiver/exporter for now, as you are correct that they are not 1-1 to the ones we have in this repo here.
