Public NAT gateway |
1 minute |
|
inbound_bandwidth_ratio |
Inbound Bandwidth Usage |
Inbound bandwidth usage of servers using the SNAT function The maximum bandwidth supported by a NAT gateway is 20 Gbit/s. Inbound bandwidth usage = Used bandwidth/Maximum bandwidth of the NAT gateway x 100%. Unit: percent  NOTE:
This metric is used to monitor the performance of NAT gateways instead of the EIP bandwidth. |
