Type

Feature

Lineage

Depends on ldraney/DORA#1 (exporter must emit the tier label first).

Repo

forgejo_admin/pal-e-platform

User Story

As a platform operator
I want playground repos excluded from DORA composite scores
So that metrics reflect real production health

Context

The current Grafana DORA dashboard has a $repo variable that shows every Forgejo repo. Once the exporter emits a tier label (#1), the dashboard needs a tier dropdown so overview panels aggregate only production repos by default.

File Targets

Files the agent should modify or create:

terraform/dashboards/dora-dashboard.json — add tier variable, update overview panel queries

Files the agent should NOT touch:

terraform/modules/monitoring/main.tf — no infra changes needed

Acceptance Criteria

Dashboard has a tier dropdown: Tier 1 (Production), Tier 1+2 (All Tracked), All
Overview stat panels filter by tier=~"$tier"
Default selection is Tier 1 (Production)

Test Expectations

Manual: verify dropdown appears and filters panels correctly in Grafana

Constraints

Dashboard JSON is managed in Terraform — changes must be applied via tofu apply
Must not break existing $repo variable functionality

Checklist

Tests pass
