 {{< note >}}The management traffic for NGINX instances is billed as a `Virtual Network Peering - Intra-Region Egress` charge. This charge includes the data for shipping metrics and logs. The cost for shipping metrics data is approximately $0.03/month. If you enable NGINX logging the cost increases by roughly $0.005 per GB of logs NGINX generates. To estimate this, multiply the number of requests by the average log line size of the access_log format you have configured.
