Nov 1, 2025

November 2025 focused on reliability, security, and developer productivity across open-telemetry/opentelemetry-collector-contrib and perses/perses. Key features and fixes included robust Azure API metrics collection that respects per-metric aggregations to avoid 501 errors, with updates to metrics definitions, documentation, and tests. We also enhanced testing infrastructure for Azure data models by introducing MockInput abstractions to improve readability and maintainability of test code. Governance improvements for azuremonitorreceiver were implemented by moving a long-time maintainer to emeritus status, clarifying the review process and ownership. In Perses, OAuth/OIDC state encoding was hardened to securely preserve redirect paths and fix state formatting to prevent CSRF and encoding issues. RP-initiated logout for OIDC was added, including documentation updates reflecting Microsoft Entra ID changes, and a fix to allow API prefix to be included in OIDC/OAuth2 redirects to ensure correct routing across API paths. Overall, these changes increase reliability, security, and maintainability while strengthening governance and cross-repo collaboration, delivering tangible business value in operational stability and secure authentication flows.
