Monitor

Source: src/AWS/InternetMonitor/Monitor.ts

An Amazon CloudWatch Internet Monitor monitor — measures internet availability and performance between your AWS-hosted application and your end users’ city-networks (client locations and ASNs, typically ISPs).

A monitor is built from the application resources you add to it: VPCs, Network Load Balancers, CloudFront distributions, or WorkSpaces directories. Cost is controlled by capping the number of monitored city-networks (maxCityNetworksToMonitor) or the percentage of traffic monitored (trafficPercentageToMonitor).

Creating a Monitor

Monitor for a VPC

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

const monitor = yield* InternetMonitor.Monitor("AppMonitor", {
  resources: [`arn:aws:ec2:us-east-1:123456789012:vpc/${vpc.vpcId}`],
  maxCityNetworksToMonitor: 100,
});

Monitor a percentage of traffic

const monitor = yield* InternetMonitor.Monitor("AppMonitor", {
  resources: [cloudfrontDistributionArn],
  trafficPercentageToMonitor: 50,
});

Health Events

const monitor = yield* InternetMonitor.Monitor("AppMonitor", {
  resources: [vpcArn],
  maxCityNetworksToMonitor: 100,
  healthEventsConfig: {
    AvailabilityScoreThreshold: 90,
    PerformanceScoreThreshold: 90,
  },
});

Log Delivery

const monitor = yield* InternetMonitor.Monitor("AppMonitor", {
  resources: [vpcArn],
  maxCityNetworksToMonitor: 100,
  internetMeasurementsLogDelivery: {
    S3Config: {
      BucketName: bucket.bucketName,
      LogDeliveryStatus: "ENABLED",
    },
  },
});
