snat_connection_ratio

SNAT Connection Usage Rate

The percentage of available SNAT connections used by servers for which the SNAT rules are configured on the NAT gateway

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

Unit: Percent

>= 0

NAT gateway

1 minute

inbound_bandwidth_ratio

Inbound Bandwidth Usage Rate

The percentage of available inbound bandwidth used by servers using the SNAT function. The maximum bandwidth supported by a NAT gateway is 20 Gbit/s.

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.

>= 0

NAT gateway

1 minute

outbound_bandwidth_ratio

Outbound Bandwidth Usage Rate

The percentage of available outbound bandwidth used by servers using the SNAT function

The maximum bandwidth supported by a NAT gateway is 20 Gbit/s. Outbound 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.
