Focus areas

Questions, observations, and opportunities

• Point of entry for Observability Getting Started.
  - V3 PoE more closely aligns with Serverless PoE.
  - Q: Are we moving away from the card-style intro in 8.x series docs?

Stateful/serverless

• V3 PoE
  - Two source files to reconcile:
  - https://github.com/elastic/docs-content/blob/main/solutions/observability.md?plain=1
  - https://github.com/elastic/docs-content/blob/main/raw-migrated-files/docs-content/serverless/what-is-observability-serverless.md?plain=1
  - "Get started with Logs: Add your log data to Elastic Observability Serverless and start exploring your logs" is hard-coded for serverless and links to serverless content.
  - "Get started with Metrics: Add your log data to Elastic Observability Serverless and start exploring your logs" is hard-coded for serverless. The topic it links to has been updated with tab versions.
• Get Started section is serverless-focused. Needs versioning eval and implementation.
  - [ ] https://docs-v3-preview.elastic.dev/elastic/docs-content/tree/main/solutions/observability/get-started/quickstart-monitor-hosts-with-opentelemetry#_collect_your_data. Tabs for serverless and stateful aren't laid out properly.
• What is Elastic Observability?. Try consolidating page for serverless and stateful:
