NAT Gateway Monitoring Integration

NAT gateways pave the way for seamless traffic flow from instances in the private subnet to the internet or other AWS services. Monitor NAT gateways with Site24x7 to identify traffic disruptions quickly and measure the volume of traffic flow.

Setup and configuration

  • If you haven't done it already, enable access to your AWS resource by creating Site24x7 as an IAM user or by creating a cross-account IAM role between your account and Site24x7's AWS account. Learn more.
  • Next, In the Integrate AWS Account page, please make sure the NAT Gateway checkbox is selected in the Services to be discovered field.  Learn more.

Policies and permissions

Please make sure the following read level actions are present in the IAM policy assigned to Site24x7 entity. Learn more.

Polling frequency

Site24x7 queries AWS to collect NAT gateway performance metrics according to the configured poll frequency. The minimum poll interval supported is one minute, and the maximum is 24 hours. Learn more.
