Network monitoring
The topics in this section describe CloudWatch network and internet monitoring capabilities provided by Amazon CloudWatch Internet Monitor and Amazon CloudWatch Network Monitor. These services help you to gain operational visibility into the network and internet performance and availability of your applications hosted on AWS.
Internet Monitor uses the connectivity data that AWS captures from its global networking footprint to calculate a baseline of performance and availability for internet-facing traffic. You can see a global view of traffic patterns and health events, and easily drill down into information about events. You can also get alerts for internet health events that affect your application clients. In addition, you can use insights that Internet Monitor provides to explore potential improvements to your client experience, by using Amazon CloudFront or routing through different AWS Regions.
Network Monitor uses a fully-managed agent approach to enable you to track and visualize latency and packet loss for hybrid network connections. To gather measurements and enable Network Monitor to create health event alerts for your application, you create probes that are sent from your resources hosted on AWS to on-premises destination IP addresses. You don't need to install additional agents to monitor your network performance. As with Internet Monitor, you can set alerts and thresholds, get information to help you quickly troubleshoot issues, and then take action to improve your end user experience.
