GetMetricStatistics

Source: src/AWS/CloudWatch/GetMetricStatistics.ts

Runtime binding for cloudwatch:GetMetricStatistics — fetch aggregated datapoints for a single metric (the older single-metric query API; prefer GetMetricData for metric math or multi-metric queries).

Provide CloudWatch.GetMetricStatisticsHttp on the hosting Lambda Function to satisfy the requirement.

Querying Metrics

// init — grants cloudwatch:GetMetricStatistics
const getMetricStatistics = yield* AWS.CloudWatch.GetMetricStatistics();

// runtime
const now = yield* Effect.sync(() => Date.now());
const result = yield* getMetricStatistics({
  Namespace: "MyApp/Payments",
  MetricName: "PaymentProcessed",
  StartTime: new Date(now - 3_600_000),
  EndTime: new Date(now),
  Period: 60,
  Statistics: ["Sum"],
});
const datapoints = result.Datapoints ?? [];
