Supported Metrics¶
Description¶
This section describes metrics reported by NAT Gateway to Cloud Eye as well as their namespaces, monitoring metrics, and dimensions. You can use the management console or the APIs provided by Cloud Eye to query the metrics generated for NAT Gateway.
Namespace¶
SYS.NAT

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 | Public NAT gateway | 1 minute |
inbound_bandwidth | Inbound Bandwidth | Total bandwidth sent out through the public NAT gateway from the public network Unit: bit/s | >= 0 bits/s | Public NAT gateway | 1 minute |
outbound_bandwidth | Outbound Bandwidth | Total bandwidth sent out through the public NAT gateway from the VPC Unit: bit/s | >= 0 bits/s | Public NAT gateway | 1 minute |
inbound_pps | Inbound PPS | Packets received by the public NAT gateway from the public network per second Unit: count | >= 0 | Public NAT gateway | 1 minute |
outbound_pps | Outbound PPS | Packets received by the public NAT gateway from the VPC per second Unit: count | >= 0 | Public NAT gateway | 1 minute |
inbound_traffic | Inbound Traffic | Traffic sent through the public NAT gateway from the public network Unit: byte | >= 0 bytes | Public NAT gateway | 1 minute |
outbound_traffic | Outbound Traffic | Traffic sent through the public NAT gateway from the VPC Unit: byte | >= 0 bytes | 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. Unit: percent | >= 0 | 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 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 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 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 |

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 |
