idle_nat_gateway
What it finds
Idle NAT Gateway: one of the VPC and load balancing checks in the network optimization group. Checks in this group look for: network resources that carry no traffic, or sit unattached, duplicated or in front of nothing.
Why it costs money
Gateways, load balancers and addresses bill by the hour once they exist, with or without traffic.
How it is detected
Zero bytes transferred for 7 days
Detection confidence: HIGH. This is the criterion from our public docs. It runs in a local scan with your own read-only credentials.
Run it yourself
Nothing leaves your machine. The local scan has no telemetry.
