Aspire Dashboard's Docker image does not have any command line tool available to do this. In practice this is OK for dev since OTEL exporters retry.

No need to expose this port outside Docker.

Why not using Grafana? To have traces, metrics and logs at the same time!

Aspire Dashboard handles the 3 OTEL signals too:
When you search the web:
For a local development environment without the need for persistence, the .NET Aspire Dashboard is superior to Grafana due to its zero-config setup, instant OpenTelemetry visualization, and low resource overhead. It is designed as an ephemeral, in-memory tool perfect for local debugging
I learned about it here.

This Grafana image is also with 0 config: https://grafana.com/docs/opentelemetry/docker-lgtm/

As grafana is also the stack of APA, if we can get Grafana for the same amount of config, that's equally good

Grafana otel-lgtm vs Aspire Dashboard:
- pros:
- same interface as what our prod users are used to
- built-in healthcheck in Docker image to only start our app once the OTEL stack is ready
- cons:
- 2GB instead of 200MB
-> I switched to Grafana in d461976.
