Queries actual or amortized costs for an Azure scope with grouping and time filtering. WAF Cost Optimization: identify top-spending services and resource groups, track daily trends, and perform chargeback/showback using tag-based grouping. CAF: use management group scope for cross-subscription cost reports aligned to landing zones.

Retrieves cost forecasts based on current usage trends. WAF Cost Optimization: compare forecast vs budget to detect overspend risk proactively. Set budgets with 100% forecasted threshold to receive early warning alerts (see azure_budget_create).

Lists available dimensions for cost grouping and filtering at a given scope. Use this to discover valid values for the groupBy parameter in azure_cost_query. WAF: discover available tag keys for chargeback/showback analysis before querying.

Lists active cost alerts for a scope (budget breaches, credit warnings, quota violations, anomalies). WAF Cost Optimization: monitor alerts to detect unexpected cost spikes before they escalate. Complement with azure_budget_list to correlate alerts with budget thresholds.

Lists all cost budgets at a given scope with current spend, thresholds, and alert status. WAF Cost Optimization: verify every workload has budget coverage with 80% and 100% alert thresholds. CAF: every landing zone subscription should have at least one monthly budget.

Retrieves full details of a specific budget including current and forecasted spend, all alert notification thresholds, and filter configuration.

Creates or updates a cost budget with WAF-recommended alert thresholds. Default notifications: 80% actual, 100% actual, 100% forecasted — first line of defense against overruns. WAF Cost Optimization: always set both actual and forecasted alerts on every workload budget. CAF: align timeGrain with billing cycles; include Owner/Contributor in contactRoles for governance. If a budget with the same name already exists at the scope it will be updated in-place.

Permanently deletes a cost budget. This action cannot be undone.

Retrieves Azure Advisor cost optimization recommendations for a subscription. Covers: right-sizing underutilized VMs, deleting idle resources (unattached disks, unused IPs), purchasing reservations or savings plans for predictable workloads, and removing empty resource groups. WAF Cost Optimization: address High impact recommendations first for maximum savings. CAF FinOps: run across all landing zone subscriptions to enforce cost governance. Note: Advisor operates at subscription scope; management group scope is not supported.
