Not a requirement for this PR, but I'm missing a link in the localtest dotnet app to make this more discoverable, and ideally a message informing that local telemetry is not running if it isn't (just send a http request to verify).

Docs does currently not suggest using the Makefile, so adding everything together in a single makefile would be nice. Potentially behind a --profile flag (as we use in --profile localtest).

For the other services we have separate compose files for docker and podman. Would that be required here also?

This is very nice @martinothamar 💯.

How "built in" should monitoring stack be - included in the primary docker compose file or a separate one? The backends are relatively lightweight, but not free

IMO it should be in a separate one.

Grafanas own LGTM-stack development image can also be considered but it is far less flexible, and harder to match the fully deployed solution: https://github.com/grafana/docker-otel-lgtm

What are we missing exactly from running that image? Is it adding dashboards?

Good point, now there is a Grafana menu item

Opted for using compose profiles in the latest commit

• --profile "monitoring" brings up existing setup + monitoring profile
• --profile "*" brings up existing setup + every other profile
• No profile specified brings up the existing setup

I was guessing that configuration would be more of a hassle but looking at it now maybe it isn't. I won't be able to specify command in the compose file, and for dashboards I will have to get the grafana version number, but the rest seems like it should work fine (the actual config files and such). I will give it a shot

Running out of time a bit here so I'll keep the LGTM stack as is for now. Other than that

• Grafana is behind proxy (no exposed port)
• Only OTel GRPC port exposed on OTel collector
• Some updates to the dashboard (will update screenshot in a bit)
• Updated README
• Implemented podman stuff
• Implemented a simpler run.cmd cross-platform script and documented it as preview
