inbound_bandwidth	Inbound Bandwidth	Total bandwidth sent out through the public NAT gateway from the public network	≥ 0	bit/s	1024 (IEC)	Public NAT gateway	1 minute
outbound_bandwidth	Outbound Bandwidth	Total bandwidth sent out through the public NAT gateway from the VPC	≥ 0	bit/s	1024 (IEC)	Public NAT gateway	1 minute
inbound_pps	Inbound PPS	Packets received by the public NAT gateway from the public network per second	≥0	Count	N/A	Public NAT gateway	1 minute
outbound_pps	Outbound PPS	Packets received by the public NAT gateway from the VPC per second	≥0	Count	N/A	Public NAT gateway	1 minute
inbound_traffic	Inbound Traffic	Traffic sent through the public NAT gateway from the public network	≥0	Bytes	1024 (IEC)	Public NAT gateway	1 minute
outbound_traffic	Outbound Traffic	Traffic sent through the public NAT gateway from the VPC	≥0	Bytes	1024 (IEC)	Public NAT gateway	1 minute
snat_connection_ratio	SNAT Connection Usage Rate	Usage rate of SNAT connections The maximum number of connections is the number of connections allowed by NAT gateway specifications. For details, see NAT Gateway Specifications.	≥ 0	%	N/A	Public NAT gateway	1 minute
inbound_bandwidth_ratio	Inbound Bandwidth Usage Rate	Ratio of the bandwidth used by the public NAT gateway to route traffic from the public network 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 × 100%. NOTE: This metric is used to monitor the performance of public NAT gateways instead of the EIP bandwidth.	≥ 0	%	N/A	Public NAT gateway	1 minute
outbound_bandwidth_ratio	Outbound Bandwidth Usage Rate	Ratio of the bandwidth used by the public NAT gateway to route traffic from the VPC 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 × 100%. NOTE: This metric is used to monitor the performance of public NAT gateways instead of the EIP bandwidth.	≥ 0	%	N/A	Public NAT gateway	1 minute
total_inbound_udp_bandwidth	Total Inbound Bandwidth (UDP)	Total bandwidth sent out through the public NAT gateway over UDP from the public network	≥ 0	bit/s	1024 (IEC)	Public NAT gateway	1 minute
total_outbound_udp_bandwidth	Total Outbound Bandwidth (UDP)	Total bandwidth sent out through the public NAT gateway over UDP from the VPC	≥ 0	bit/s	1024 (IEC)	Public NAT gateway	1 minute
total_inbound_tcp_bandwidth	Total Inbound Bandwidth (TCP)	Total bandwidth sent out through the public NAT gateway over TCP from the public network	≥ 0	bit/s	1024 (IEC)	Public NAT gateway	1 minute
total_outbound_tcp_bandwidth	Total Outbound Bandwidth (TCP)	Total bandwidth sent out through the public NAT gateway over TCP from the VPC	≥ 0	bit/s	1024 (IEC)	Public NAT gateway	1 minute
packets_drop_count_snat_connection_beyond	Packets Dropped (Excessive SNAT Connections)	Number of packets dropped by the public NAT gateway due to excessive SNAT connections	≥ 0	Count	N/A	Public NAT gateway	1 minute
packets_drop_count_pps_beyond	Packets Dropped (Excessive PPS)	Number of packets dropped by the public NAT gateway due to excessive PPS	≥ 0	Count	N/A	Public NAT gateway	1 minute
packets_drop_count_eip_port_alloc_beyond	Packets Dropped (When All EIP Ports Allocated)	Number of packets dropped by the public NAT gateway when all EIP ports have been allocated	≥ 0	Count	N/A	Public NAT gateway	1 minute
