snat_connection_ratio

SNAT Connection Usage

SNAT connection usage of the NAT gateway

The maximum number of connections is the number of connections allowed by NAT gateway specifications.

Unit: percent

≥ 0

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 public NAT gateway is 20 Gbit/s. Inbound bandwidth usage = Used bandwidth/Maximum bandwidth of the public NAT gateway x 100%.

Unit: percent

NOTE:

This metric is used to monitor the performance of public NAT gateways instead of the EIP bandwidth.

≥ 0

Public NAT gateway

1 minute

outbound_bandwidth_ratio

Outbound Bandwidth Usage

Outbound bandwidth usage of servers using the SNAT function

The maximum bandwidth supported by a public NAT gateway is 20 Gbit/s. Outbound bandwidth usage = Used bandwidth/Maximum bandwidth of the public NAT gateway x 100%.

Unit: percent

NOTE:

This metric is used to monitor the performance of public NAT gateways instead of the EIP bandwidth.
