Exports daily AWS billing data from Cost and Usage Reports (S3 parquet) to Last9 as gauge metrics with correct historical timestamps. Metrics: aws.cost.unblended (USD), aws.usage.quantity — grouped by service, account, region, usage_type. Handles both CUR v1 (slash) and v2 (snake_case) parquet column naming.

Add aws.cost.amortized metric using per-type effective cost columns (savings_plan_savings_plan_effective_cost for SP, reservation_effective_cost for RI) — shows true cost after RI/SP amortization vs unblended. Add COST_ALLOCATION_TAGS env var: forwards CUR resource_tags_user_* columns as aws.tag.* metric dimensions for team/env/project cost slicing. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Generates 7 days of synthetic CUR rows covering Usage, SavingsPlanCoveredUsage, DiscountedUsage, and Tax line items. Validates amortized < unblended for SP, amortized > 0 for RI with $0 unblended, Tax exclusion, and tag forwarding. Sends real OTLP to Last9 — no AWS account required.

Restructure as numbered setup steps (enable CUR, IAM policy, configure+run). Add test_local.py to verification section. Fix log line in verification snippet. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Simple alternative to CUR — polls Cost Explorer API (ce:GetCostAndUsage), no S3 or CUR setup required. Data flows within minutes. Exports aws.cost.unblended and aws.cost.amortized grouped by service, account, region with correct historical timestamps via direct OTLP/HTTP JSON.

…lick deploy Self-contained template with inline Lambda code (urllib, no external deps). Creates IAM role, Lambda (Python 3.13, 5min timeout), and EventBridge daily schedule. Customer uploads to AWS console, fills OtlpHeaders, done. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
