Description

Metrics! Sentry will support Metrics finally! First we need all of our SDKs to support Metrics, this ticket is track the implementation and rollout of Metrics across sentry SDKs. Specification for implementation is in the develop spec linked below.

Project Board

Related to requirement of adding Metrics to each SDK:

• Metrics API
• Metrics summaries
• Span Aggregator (trace correlation)
• code location
• Normalizaiton [Chore] Implement Tag Normalization/Restrictions  #56
• SDK Docs

Related to product and onboarding:

Regarding metrics onboarding, we want to follow the Install , Configure , Verify structure.
The steps that need to be done are:
Add the platforms to the list of platforms that support custom metrics (customMetricBackendPlatforms & customMetricFrontendPlatforms ) in platformCategories.tsx
Add the onboarding content as customMetricsOnboarding entry to the Docs object exported by the platform'd docs file (e.g. rust)
You can find an example PR that does this for serverless javascript platforms here.
ATM the guides are very uniform in their content. We collected them here in Notion

• Project Creation Onboarding Getting Started Doc
• Set Up Custom Metrics Wizard here & .NET example here
• Tested with sample app - Docs and Product Onboarding
