Metrics

**Table 1** NAT gateway metrics
Metric ID	Name	Description	Value Range	Monitored Object	Monitoring Period (Raw Data)
snat_connection	SNAT Connections	Number of SNAT connections of the NAT gateway Unit: Count	≥ 0	NAT gateway	1 minute
inbound_bandwidth	Inbound Bandwidth	Inbound bandwidth of servers using the SNAT function Unit: bit/s	≥ 0 bits/s	NAT gateway	1 minute
outbound_bandwidth	Outbound Bandwidth	Outbound bandwidth of servers using the SNAT function Unit: bit/s	≥ 0 bits/s	NAT gateway	1 minute
inbound_pps	Inbound PPS	Inbound PPS of servers using the SNAT function Unit: Count	≥ 0	NAT gateway	1 minute
outbound_pps	Outbound PPS	Outbound PPS of servers using the SNAT function Unit: Count	≥ 0	NAT gateway	1 minute
inbound_traffic	Inbound Traffic	Inbound traffic of servers using the SNAT function Unit: byte	≥ 0 bytes	NAT gateway	1 minute
outbound_traffic	Outbound Traffic	Outbound traffic of servers using the SNAT function Unit: byte	≥ 0 bytes	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 a NAT gateway type. . Unit: Percent	≥ 0	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. Unit: Percent	≥ 0	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 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.	≥ 0	NAT gateway	1 minute
