Cloud Insights offers a detailed topology of how your cloud native assets are connected together logically, your historical inventory, and a comprehensive end-to-end traffic flow. Events occuring within your cloud infrastructure, such as configuration changes and operational scaling events, are represented in the topology view as well as in the timeline. These visualizations are available in the Cloud Insights section of the ThousandEyes app and as the Cloud layer in Cloud and Enterprise Agents > Views.
The inventory shows the cloud topology discovered through your integration with your cloud provider. Inventory reports the last 30 days of ingested data and it is refreshed every 5 minutes.
With the Cloud Insights inventory, you can see all your AWS networking, content delivery, and compute assets grouped by asset type, including ALB, NAT Gateway, Internet Gateway, across all AWS accounts, in one dashboard. You can see all your AWS assets in the context of their respective public or private subnets, availability zones (AZ), virtual private cloud instances (VPC), AWS regions, and AWS accounts. The inventory view shows what assets your presently have available in your AWS cloud infrastructure as well as assets from the past that may not be presently available.
Hover over an item to display a tooltip that shows additional details. Click on a security group or subnet to see its details. Filtering assets by service and filtering by tags is also supported.

Cloud Insights metrics can be used to visualize change events and traffic flow over time by ingesting VPC flow logs. In addition to the timeline, Cloud Insights provides a traffic table in the area below the timeline. Filters and grouping are also available.
Traffic views can be filtered by several dimensions, such as by cloud account, region, availability zone, VPC, application, enabling flexible and contextual views of performance. Filter options are available for each local and remote resource. Local resources are where the VPC flow logs are captured. Remote resources are where the VPC flow logs are destined.
Filtering selections are available both above the timeline and below. Click on the ... for additional options.
IP address, Service, and Resource change the view to a 6-hour window. For these metrics, only history for the past 6 hours is rendered in the timeline.
The following traffic flow metrics are available under Cloud Insights views:
Metric | |
Total Throughput | Sum of VPC Accept Actions for traffic going to or coming from outside AWS. Limited to traffic going through the test ingress point in AWS. |
Rejected Bandwidth | Sum of VPC Reject Actions |
Connections per Second | Sum of new TCP connections |
Cloud Insights tracks configuration change and operational scaling events and state changes across any element of the virtual infrastructure that serves your application. In addition to problematic infrastructure elements, a common cause for application downtime is changes made by an automated process or a live human. Monitoring change events not only allows you to determine what changed at what time, but also to correlate that change with application availability and other metrics.
To view change event metrics, select All Events from the pop-up menu.
A view of change events is also available in the Cloud layer of the Cloud and Enterprise Agents views. Configuration changes and operational changes are colored on the topology view. Note that not all changes negatively impact applications and services.
You can view a diff of the change, before and after the change event occurred. To view a diff, select a row containing a configuration change from the Events table located below the timeline.
You can also use the Inventory view to show the diff. Click on any row located under the Asset Name header.
Use the Events view to track configuration changes and operational events due to adding or removing instances. You can also back-test the impact of a change on a specific network instance for root cause analysis and troubleshooting.
The table tab displays a list of resources that meet the filter and grouping criteria specified just below the timeline. With the table tab view you can:
Use the grouping and filter criteria to determine what is displayed.
Click on column headers to change the sort order.
Hover over a row to display more details about the row item.
Click the ... at the end of the row to filter based on the selected row item.
The map tab groups cloud environment resources by region and displays them using a map visualization. Use the + and - buttons in the upper right to zoom in and zoom out, respectively. Hover over any item to display more details about the resource.
Cloud Insights are integrated with the Cloud and Enterprise Agents (CEA) views both as a swimlane below the timeline showing configuration change and operational events, and as a traffic topology map.
The Cloud Configuration layer shows your cloud environment behind the Load Balancer that is serving your application. For AWS environments, this can also be the Global Accelerator. This view pulls in your cloud native inventory for the specific service, providing a logical service map of how your application is being served. You can use the traffic layer to visualize how your application is distributed within your cloud provider networks.
The Cloud Configuration layer is available under Cloud and Enterprise Agents views. To navigate to the Cloud Configuration layer, click on the Cloud label to the left of the CEA timeline. If you do not see a Cloud Configuration layer it means you have not configured a supported cloud provider integration.
Available metrics for the Cloud Configuration layer timeline are Outside Cloud Throughput and Event Count. You can choose to display one or both metrics at the same time.
When attempting to correlate traffic flow log data with other metrics, a related spike may show up in the next adjacent bucket. This is because traffic flow log data is aggregated every 5 minutes.
When the Cloud Configuration layer view is selected, the map area below the timeline displays the traffic topology under the topology tab. Operational events are highlighted in red while configuration change events are highlighted in blue.
You can also view a comparison of topology changes without having to manually go back in time on the timeline.
Amazon Web Services (AWS)
For AWS, the traffic topology tab shows what's behind the AWS Global Accelerator or Load Balancer that is serving your application. You can distinguish between traffic flow that originates outside AWS and is destined in AWS, originates and is destined in AWS, and originates in AWS and is destined outside AWS. This means that you can identify network blindspots in the context of where traffic originates and is destined. You can also see traffic flow size (bytes/sec) between each hierarchical AWS instance, e.g. AWS account, AWS region, VPC, AZ, Subnet, AWS instance, and AWS elastic network interface.
If any configuration change or operational events are selected in the traffic layer timeline, they will be listed under the events tab underneath the timeline.
Click on any row to view details of the event. Configuration changes show a diff of the change that was made. For AWS resources, you can click on the blue Explore in AWS button in the upper right corner to access the AWS console.
Use the Traffic tab to view a detailed list of servers along with specific throughput metrics. This list can be grouped and filtered using the selection menus at the top of the list. This functions in the same way as the Cloud Insights Table tab.
