AWS Transit Gateway Monitoring Integration
AWS Transit Gateway helps you to centrally manage the connectivity policies across multiple Amazon Virtual Private Clouds (VPCs) and ensures seamless on-premises connectivity. In this way, Transit Gateway provides ways to simplify network architecture, reduce operational overhead, and centrally manage external connectivity.
With Site24x7's integration, monitor AWS Transit Gateway and collect critical performance metrics like the number of bytes sent or received, number of packets sent or received, and even the number of bytes or packets dropped.

Setup and configuration
1. If you haven't already, enable access to your AWS resources between your AWS account and Site24x7's AWS account by either:
- Creating Site24x7 as an IAM user, or
- Creating a cross-account IAM role. Learn more
2. On the Integrate AWS Account page, check the appropriate checkbox for Transit Gateway. Learn more
Policy and permissions
Site24x7 uses various AWS Transit Gateway APIs to collect information about your storage gateway. Assign the AWS managed policy ReadOnlyAccess to the Site24x7 entity (IAM user or IAM role) to help Site24x7 collect metrics and metadata. If you want to assign a custom policy, please make sure the following read-level actions are present in the policy JSON. Learn more
- "ec2:DescribeTransitGatewayAttachments",
- "ec2:DescribeTransitGateways",
- "ec2:DescribeTransitGatewayPeeringAttachments",
- "ec2:DescribeTransitGatewayVpcAttachments",
- "ec2:DescribeAddresses"
Threshold configuration
You can set thresholds and be notified when the route table is modified or disassociated in the Admin > Configuration Profiles > Threshold and Availability (+) > Threshold Configuration section.Toggle to Yes, for the Notify when route table is modified and Notify as Trouble when route table is disassociated options to receive notifications.
Polling frequency
Site24x7 queries AWS to collect Transit Gateway performance metrics according to the configured poll frequency. The minimum poll interval supported is one minute and the maximum is 24 hours. Learn moreTransit gateway performace metrics

Summary
Gain an overview of events occurring within each transit gateway with statuses like Down, Critical, Trouble, Maintenance, Anomaly, and Suspended. Obtain the time series charts for Throughout in Bytes, Throughout in Packets, Bytes Drop Chart, and Packets Drop Chart. All the time series charts have the average, minimum, and maximum values listed. Additionally, you can also obtain a history outlined for whenever your monitor has a Down or Trouble status, with details like Start Time to End Time, Duration, and comments, if any.
Configuration
The configuration details of a Transit Gateway are provided under this tab. Details on the Region, Transit Gateway ID, Association Route Table ID, Propagation Route Table ID, and many more are elaborated in this section.
Monitored resources
On the Monitored Resources tab, you can view a list of associated VPC-VPNs, Transit Gateway attachments, and resource names. Click on an individual listing to see performance and resource usage stats associated with that resource. You can also set thresholds and be notified when any of these services fail by clicking the pencil icon under Action.
Attachments
The Attachments tab provides information on the Name, Attachment ID, Resource ID, Availability State, and Type of the Transit Gateway in use.
Log report
Here, you can view the status, and polling activities carried out along with a time stamp, for each monitor. According to the metrics you monitor, you can obtain the metric data information for each polled instance as well.
