February 2025 performance highlights across grafana/jsonnet-libs and grafana/terraform-provider-grafana. Key features delivered include: (1) Static Exporter HTTP config defaults: make withHttpConfig the default, introduce withoutHttpConfig, and adjust deployment to conditionally mount the httpd config so the exporter is scraped by Prometheus 3.x by default (commit 8948a8a3a8b3dacb3a6ff7074617970b04792a76). (2) Grafana Terraform Provider: add allowed_subnets to resource_access_policy to enable CIDR-based IP allow lists, with validation and documentation/schema updates (commit 8a269eaeda62ae32590692187280ec80945e602a). These changes fix default exporter behavior gaps and strengthen access control. Overall impact and accomplishments: Improved security posture and deployment consistency, with out-of-the-box Prometheus 3.x scraping support and enhanced governance for access policies. Demonstrated capabilities in Terraform provider schema evolution, CIDR validation, and deployment configuration. Technologies/skills demonstrated: Terraform provider schema extension, CIDR notation validation, deployment/configuration tuning (httpd config mounting), Prometheus scrapes compatibility (Prometheus 3.x), and documentation updates.
