指标参考¶

所有业务指标和 target 级运行指标都包含 target。金额指标不能跨 currency、provider、cost_basis 聚合，除非查询明确是在比较会计视图。

`aws_cost_month_forecast_mean_amount`	gauge	`provider,cost_basis,currency`	包含今天的剩余月度预测均值
`aws_cost_month_forecast_lower_bound_amount`	gauge	`provider,cost_basis,currency`	预测下界

`aws_cost_account_info`	gauge	`linked_account_id,account_name,account_status`	非敏感 Organizations 元数据，值为 1
`aws_cost_tag_daily_amount`	gauge	`provider,cost_basis,currency,tag_key,tag_value`	allowlist Tag 当日成本
`aws_cost_tag_month_to_date_amount`	gauge	`provider,cost_basis,currency,tag_key,tag_value`	allowlist Tag 月累计成本

Metric	类型	Labels
`aws_commitment_utilization_ratio`	gauge	`target,commitment_type,time_unit`
`aws_commitment_coverage_ratio`	gauge	`target,commitment_type,time_unit`
`aws_commitment_unused_hours`	gauge	`target,commitment_type,time_unit`
`aws_commitment_covered_spend_amount`	gauge	`target,commitment_type,time_unit,currency`
`aws_commitment_on_demand_cost_amount`	gauge	`target,commitment_type,time_unit,currency`
`aws_commitment_net_savings_amount`	gauge	`target,commitment_type,time_unit,currency`
`aws_cost_anomaly_active`	gauge	`target`
`aws_cost_anomaly_count`	gauge	`target`
`aws_cost_anomaly_impact_amount`	gauge	`target,currency`
`aws_cost_anomaly_last_detected_timestamp_seconds`	gauge	`target`

commitment_type 只允许 savings_plan、reservation，不暴露 Plan、Reservation 或 Anomaly ID。

全部使用 target,budget_name,currency,budget_type,time_unit：

只接受 COST Budget；缺失 actual/forecast 时省略相应 series。

Metric	类型	主要 Labels
`aws_cost_exporter_collector_up`	gauge	`target,collector`
`aws_cost_exporter_last_success_timestamp_seconds`	gauge	`target,collector`
`aws_cost_exporter_last_attempt_timestamp_seconds`	gauge	`target,collector`
`aws_cost_exporter_cache_age_seconds`	gauge	`target,collector`
`aws_cost_exporter_snapshot_series`	gauge	`target,collector`
`aws_cost_exporter_refresh_total`	counter	`target,collector,status`
`aws_cost_exporter_refresh_duration_seconds`	histogram	`target,collector`
`aws_cost_exporter_aws_api_requests_total`	counter	`target,operation,status`
`aws_cost_exporter_aws_api_retries_total`	counter	`target,operation,reason`
`aws_cost_exporter_aws_api_request_duration_seconds`	histogram	`target,operation`
`aws_cost_exporter_scheduler_skipped_runs_total`	counter	`target,collector,reason`
`aws_cost_exporter_dimension_overflow_values_total`	counter	`target,dimension`
`aws_cost_exporter_pagination_pages_total`	counter	`target,operation`
`aws_cost_exporter_cache_publish_errors_total`	counter	`target,collector,operation`
`aws_cost_exporter_build_info`	gauge	`version,revision,go_version`
`aws_cost_exporter_scheduler_shutdown_timeouts_total`	counter	进程全局

operation、status、reason、collector、provider、basis、commitment label 都是有界枚举，原始 AWS 错误和 Request ID 不会成为 label。

逻辑请求、成功分页、retry 计数与 AWS 活动相关，但不等同于 AWS 实际计费 HTTP attempt。
