inbound_bandwidth	Inbound Bandwidth	Inbound bandwidth of servers using the SNAT function Unit: bit/s	≥ 0 bits/s	Public NAT gateway	1 minute
outbound_bandwidth	Outbound Bandwidth	Outbound bandwidth of servers using the SNAT function Unit: bit/s	≥ 0 bits/s	Public NAT gateway	1 minute
inbound_pps	Inbound PPS	Inbound PPS of servers using the SNAT function Unit: count	≥ 0	Public NAT gateway	1 minute
outbound_pps	Outbound PPS	Outbound PPS of servers using the SNAT function Unit: count	≥ 0	Public NAT gateway	1 minute
inbound_traffic	Inbound Traffic	Inbound traffic of servers using the SNAT function Unit: byte	≥ 0 bytes	Public NAT gateway	1 minute
outbound_traffic	Outbound Traffic	Outbound traffic of servers using the SNAT function Unit: byte	≥ 0 bytes	Public NAT gateway	1 minute
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. For details, see 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 × 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 × 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
total_inbound_udp_bandwidth	Total Inbound Bandwidth (UDP)	Total bandwidth sent out through the public NAT gateway over UDP from the public network Unit: bit/s	≥ 0 bits/s	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 Unit: bit/s	≥ 0 bits/s	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 Unit: bit/s	≥ 0 bits/s	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 Unit: bit/s	≥ 0 bits/s	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	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	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	Public NAT gateway	1 minute
