AnomalyMonitor

Source: src/AWS/CostExplorer/AnomalyMonitor.ts

A Cost Explorer anomaly detection monitor. Monitors evaluate your spend for unusual patterns; pair with an AnomalySubscription to receive alerts.

Cost Explorer is a global service — all calls are pinned to us-east-1 regardless of the stack region. Monitors are free and take effect immediately.

Creating Anomaly Monitors

Custom monitor scoped by a cost allocation tag

import * as CostExplorer from "alchemy/AWS/CostExplorer";

const monitor = yield* CostExplorer.AnomalyMonitor("TeamSpend", {
  monitorType: "CUSTOM",
  monitorSpecification: {
    Tags: { Key: "CostCenter", Values: ["10000"] },
  },
});

Dimensional monitor across all AWS services

const monitor = yield* CostExplorer.AnomalyMonitor("ServiceSpend", {
  monitorType: "DIMENSIONAL",
  monitorDimension: "SERVICE",
});
