# View Internet Monitor metrics or set alarms in CloudWatch Metrics
<a name="CloudWatch-IM-view-cw-tools-metrics-dashboard"></a>

You can view or set alarms on Internet Monitor metrics by using CloudWatch alarms and CloudWatch Metrics in the CloudWatch console. 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](IMCityNetworksMaximum.md). To learn more about setting alarms for Internet Monitor, see [Create alarms with Internet Monitor](CloudWatch-IM-create-alarm.md).

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 Amazon Web Services 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.
