Summary

  • Add all 19 caller-side Nexus Operation and handler-side Nexus request series to the Temporal Cloud OpenMetrics metrics reference.
  • Document supported and opt-in labels, metric types, latency aggregation cautions, and caller-versus-handler Namespace semantics.
  • Update the Nexus metrics overview to link to the current OpenMetrics reference.

Why

The Nexus metrics tracked by DEVPROD-1741 through DEVPROD-1746 and DEVPROD-1757 through DEVPROD-1761 are absent from the public Temporal Cloud metrics catalog. This PR is a draft pending rollout confirmation.

Metric names, help text, and supported labels are aligned with the current generated saas-external-observability implementation catalog, which is the source of truth for this change.

Validation

  • vale --config .vale-ci.ini on both changed files
  • node ./bin/check-metrics-reference.js
  • npm run build
  • Verified all 19 generated metric anchors and the Nexus overview link in the production build
