Metric Insights is part of the CloudWatch service offerings. Metric Insights provides an SQL-based query engine that can search millions of metrics in real time. Metric Insights allows you to capture trends and data patterns as they occur, enabling you to respond quickly to events using SQL-based queries. Metric Insights allows for the grouping of events for more detailed analysis. For example, you could select all EC2 instances and perform analysis on them or drill down to the region, VPC, or availability zone level based on your requirements. Using the data from insights, you could call utilities to automatically respond to events that you define or create real-time graphing for visual dashboards.
The service uses standard SQL language, or you can use the visual query editor that is included in the service. Once you have selected your metrics with the visual editor, Metric Insights will automatically generate the SQL query for you to run.
To run this feature, click the All-Metrics tab in the pane on the left of the CloudWatch console and open the Query tab, as shown in Figure 5.6.

Dashboards allow for a single-pane-of-glass view of your operations and can present the data of many different metrics in graphical form such as performance, utilization, and errors. CloudWatch dashboards are fully customizable and are created based on your requirements. Dashboards are helpful in giving operations personnel a quick overview of the collected metrics of your services.
You can visualize live data about your network and share your visualizations with outside entities even if they do not have an account with AWS or are part of your organization.
Dashboards can present a view of your complete deployment across accounts and regions by aggregating your data into one high-level dashboard. From this global dashboard, you can then drill down to more detailed dashboards without the need to manually change regions or accounts in the console.
Widgets that you create or are supplied by AWS can be added to your dashboards. Examples of widgets include gauges, lines, numbers, alarms, graphs, and more.
The AWS Transit Gateway Manager is an AWS service used to manage and monitor your global network when using the Transit Gateway service to route your company WAN traffic over the AWS network. The Transit Gateway Manager integrates with SD-WAN branch office devices and gives you network visibility across the AWS network and your private, corporate-connected networks in a single dashboard. The service simplifies the building and ongoing operations of your global network including a dashboard to visualize your network operations. Network metrics and events are monitored and displayed for ongoing network management operations.
To integrate your private network into the AWS Transit Gateway Network Manager, you create AWS Transit Gateways and then add your on-premises networks. The Transit Gateway Network Manager has SD-WAN integrations with HP/Aruba, Aviatrix, Cisco Systems, and Vera networks. With these integrations, your complete cloud and private network can be managed by the Transit Gateway Network Manager. These vendors’ management consoles can automatically provision site-to-site VPN connections to AWS from your on-premises networks.
With the graphical dashboard, utilization metrics, including packets and bytes sent and received, packet drops, and alerts, are displayed. Changes in the network topology including routing and up/down connection events are collected, and alerts are generated.
