AnomalySubscription

Source: src/AWS/CostExplorer/AnomalySubscription.ts

A Cost Explorer anomaly alert subscription. Attaches email or SNS subscribers to one or more AnomalyMonitors with a notification frequency and an impact threshold.

Cost Explorer is a global service — all calls are pinned to us-east-1 regardless of the stack region. Every property is mutable in place.

Creating Anomaly Subscriptions

Daily email digest for anomalies over $100

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

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

const subscription = yield* CostExplorer.AnomalySubscription("Alerts", {
  monitorArnList: [monitor.monitorArn],
  frequency: "DAILY",
  subscribers: [{ type: "EMAIL", address: "team@example.com" }],
  thresholdExpression: {
    Dimensions: {
      Key: "ANOMALY_TOTAL_IMPACT_ABSOLUTE",
      MatchOptions: ["GREATER_THAN_OR_EQUAL"],
      Values: ["100"],
    },
  },
});

Immediate SNS notifications

const subscription = yield* CostExplorer.AnomalySubscription("PagerFeed", {
  monitorArnList: [monitor.monitorArn],
  frequency: "IMMEDIATE",
  subscribers: [{ type: "SNS", address: topic.topicArn }],
});
