Onboarding Updates for Span-based Metrics

[ale-cota]

Problem: The current empty state of the Metrics explorer page is still focused around setting up the "old" custom metrics. We need to update it to reflect the new way of configuring metrics from span attributes.

Solution:

(1) If they’re already using performance

• Show the explorer page
• Remove the banner to set up custom metrics
• In the query 3 dot menu - Update “Metric Settings” so it’s not disabled for the out-of-the-box metrics (e.g. span.duration), but leads to the “Configure Metrics” screen with the attribute pre-selected

(2) If they’re not using performance

• Update Description
  • Track and solve what matters
  • “Query and plot metrics extracted from your span data, to visualise trends and identify anomalies. To get started, you need to enable tracing (https://docs.sentry.io/concepts/key-terms/tracing/).”
• Update CTA button
  • “Set Up Tracing” links to Tracing setup docs (https://docs.sentry.io/product/performance/getting-started/)

(3) First visit to the Metrics page

• Remove Modal with beta disclaimer (we would need to update it, it does not feel worth it at this point since there is a warning on the page already about the upcoming API changes)

First of all, thank you for explaining the issue so thoroughly 🙏 🚀

Here is my feedback:

(1) If they’re already using performance
The Metrics button in the 3 dots menu seems too hidden. How can we make customers more aware of the metrics settings?

(3) First visit to the Metrics page
In my brand-new organization, I was surprised to be immediately presented with a modal upon visiting the metrics page. I don't know why we chose this option, but wouldn't improving the displayed banner behind it be sufficient? -
This question might be irrelevant now since it seems we plan to remove the feature, but I wanted to share this feedback for future reference
