View Internet Monitor metrics or set alarms in CloudWatch Metrics
You can view or set alarms on Amazon CloudWatch Internet Monitor metrics by using CloudWatch alarms and CloudWatch Metrics in the CloudWatch console. Amazon CloudWatch Internet Monitor publishes
metrics to your account, including metrics for performance, availability, round-trip time, and throughput (bytes per second).
To find all metrics for your monitor, in the CloudWatch Metrics dashboard, see
the custom namespace AWS/InternetMonitor.
To see examples for using several of these metrics to help determine values to choose for a city-networks maximum limit for your monitor, see Choosing a city-network maximum value. To learn more about setting alarms for Internet Monitor, see Create alarms with Amazon CloudWatch Internet Monitor.
Metrics are aggregated across all internet traffic to your VPCs, Network Load Balancers, CloudFront distributions,
or WorkSpaces directories in the monitor, and to all traffic to each AWS Region and internet edge location that is monitored.
Regions are defined by the service location, which can either be all locations or a specific Region, such as us-east-1.
Note: city-networks are pairs of client locations and the ASNs the clients use (typically internet service providers or ISPs).
Internet Monitor provides the following metrics.
| Metric | Description |
|---|---|
| PerformanceScore | A performance score represents the estimated percentage of traffic that is not seeing a performance drop. |
| AvailabilityScore | An availability score represents the estimated percentage of traffic that is not seeing an availability drop. |
| BytesIn | Bytes transferred in for your application internet traffic at all application city-networks. |
| BytesOut | Bytes transferred out for your application internet traffic at all application city-networks. |
| BytesInMonitored | Bytes transferred in for your application internet traffic at monitored city-networks. |
| BytesOutMonitored | Bytes transferred out for your application internet traffic at monitored city-networks. |
| Round-trip time (RTT) | Round-trip time between the AWS Regions, ASNs (typically internet service providers or ISPs), and locations (such as cities) specific to your VPCs, Network Load Balancers, CloudFront distributions, or WorkSpaces directories. |
| CityNetworksMonitored | The number of city-networks Internet Monitor monitored for your application internet traffic. This is never more than the upper limit that you set as the maximum city-networks for the monitor. |
| TrafficMonitoredPercent | The percentage of total application internet traffic for this monitor that is represented (included) by the city-networks that Internet Monitor is monitoring. This is less than 100 (that is, less than 100%) if clients access your application in more city-networks than the maximum city-networks limit that you have set for the monitor. |
| CityNetworksFor100PercentTraffic | The number that you should set your city-networks maximum limit to if you want to monitor 100% of your application internet traffic in Internet Monitor. |
| CityNetworksFor99PercentTraffic | The number that you should set your city-networks maximum limit to if you want to monitor 99% of your application internet traffic in Internet Monitor. |
| CityNetworksFor95PercentTraffic | The number that you should set your city-networks maximum limit to if you want to monitor 95% of your application internet traffic in Internet Monitor. |
| CityNetworksFor90PercentTraffic | The number that you should set your city-networks maximum limit to if you want to monitor 90% of your application internet traffic in Internet Monitor. |
| CityNetworksFor75PercentTraffic | The number that you should set your city-networks maximum limit to if you want to monitor 75% of your application internet traffic in Internet Monitor. |
| CityNetworksFor50PercentTraffic | The number that you should set your city-networks maximum limit to if you want to monitor 50% of your application internet traffic in Internet Monitor. |
| CityNetworksFor25PercentTraffic | The number that you should set your city-networks maximum limit to if you want to monitor 25% of your application internet traffic in Internet Monitor. |
