FinOps

FinOps

🇪🇸 Español

The FinOps section (/en/finops/, /es/finops/) shows actual or amortized costs from Azure Cost Management. Data comes from Azure on demand; Goliat does not keep its own billing ledger.

What it shows

• Month selector for the last twelve months (UTC), actual or amortized cost before taxes.
• Subscription and currency filters. Currencies are never mixed.
• Total spend, daily evolution and breakdown by resource, service, subscription or resource group.
• Pie chart with the top five resources and the rest, with amounts and percentages.
• Paginated, searchable detail by resource and service. Existing resources link to the inventory; deleted resources and charges without a resource keep their amounts.
• Explicit states for loading, no data, access errors, throttling and partial results. Days without data are shown as gaps, never as zero.

Configuration

FINOPS_AUTH_MODE=default            # default | client-secret | managed-identity
FINOPS_SUBSCRIPTION_IDS=            # up to 20; empty reuses the inventory catalogue

• Locally, default uses DefaultAzureCredential, which can use your az login session.
• In Azure, the web managed identity is used. The deployment assigns Cost Management Reader on each inventory subscription.
• EA, MCA or CSP billing policies may require additional access. See Cost Management permissions.

Limits

• Private per-process cache, up to 10 minutes; partial results are kept for 30 seconds.
• At most two concurrent queries per process, with four subscriptions in parallel each. Excess requests return 429 with Retry-After: 5.
• Results are limited to 50 000 rows and 8 MiB; the cache to 16 MiB. Subscriptions over the limit are reported as unavailable, never as zero cost.
• Amounts for the current month are estimates and can be revised by Azure.

Budgets, forecasts, savings recommendations and cost allocation by current tags are not implemented.
