Metrics: Document customization options #152

Open pdudits opened 11 months ago

pdudits commented 11 months ago

OpenTelemetry SDK offers very strong tool in form of Aggregation views and customizations as documented e. g. in https://opentelemetry.io/docs/instrumentation/java/manual/#views.

Current spec gives access to this configuration, however in quite roundabout way of registering an AutoConfigurationCustomizerProvider, and in it invoking configurationCustomizer.addMeterProviderCustomizer((builder, config) -> builder.registerView(...)).

An example of achieving that as well as some motivation (adding or removing dimensions of measurement) should be provided in the spec.

Do this spec need to clarify this or a blog should be published to share how to customize metrics? @pdudits

A motivation / use case section would be fine, definetely not a normative part of spec.

@pdudits would you like to do a PR on this?

I'll try, I need to learn about a bit more first though 😁
