Monitor Huawei Cloud's NAT Gateway
Site24x7 offers monitoring support for Huawei Cloud's Network Address Translation (NAT) Gateway. Track inbound and outbound bandwidth, SNAT connection utilization, and packet drop metrics in real time, giving network teams visibility into hybrid connectivity health.
Use cases
Prevent exhaustion: When SNAT connection utilization exceeds 80%, Site24x7 alerts the network team to increase connection quota before new connection requests are dropped and private ECS instances lose outbound internet connectivity.
Investigate packet drops: Any non-zero packet drops due to EIP port exhaustion or PPS limits immediately trigger a critical alert, enabling engineers to diagnose and remediate the root cause before application connection failures accumulate.
Plan bandwidth capacity: Sustained inbound or outbound bandwidth above 80% of the gateway limit triggers a warning, providing the information to the team to upgrade the NAT Gateway specification ahead of the next traffic growth cycle.
Setup and configuration
NAT resources are auto-discovered and monitored during the Huawei Cloud integration. To enable monitoring, follow these steps:
- Navigate to Cloud > Huawei > Add Huawei Monitor. Learn how to add a Huawei Cloud monitor.
- While adding or editing a Huawei Cloud monitor, select Network Address Translation from the Service/Resource Types drop-down menu and click Save.
- Go to Cloud > Huawei. Then, select the created Huawei monitor.
- Click NAT to view the performance metrics.
Supported metrics
Inbound Traffic
Metric name |
Description |
Unit |
| Inbound Bandwidth | The rate of incoming data flowing into the NAT Gateway from external sources. | Mbps |
| Inbound Bandwidth Utilization | The percentage of the maximum inbound bandwidth capacity currently in use. | Percentage |
| Inbound Traffic | The total volume of data received by the NAT Gateway from external sources in the monitoring period. | Bytes |
| Inbound Packets Per Second | The number of inbound IP packets processed by the NAT Gateway per second. | Count/second |
| Inbound TCP Bandwidth | The rate of inbound TCP traffic specifically, measuring TCP-protocol data ingress. | Mbps |
| Inbound UDP Bandwidth | The rate of inbound UDP traffic specifically, measuring UDP-protocol data ingress. | Mbps |
Outbound Traffic
Metric name |
Description |
Unit |
| Outbound Bandwidth | The rate of outgoing data flowing out of the NAT Gateway to external destinations. | Mbps |
| Outbound Bandwidth Utilization | The percentage of the maximum outbound bandwidth capacity currently in use. | Percentage |
| Outbound Traffic | The total volume of data sent from the NAT Gateway to external destinations in the monitoring period. | Bytes |
| Outbound Packets Per Second | The number of outbound IP packets processed by the NAT Gateway per second. | Count/second |
| Outbound TCP Bandwidth | The rate of outbound TCP traffic specifically. | Mbps |
| Outbound UDP Bandwidth | The rate of outbound UDP traffic specifically. | Mbps |
SNAT and Packet Drops
Metric name |
Description |
Unit |
| SNAT Connections | The current number of active SNAT connections being maintained by the NAT Gateway. | Count |
| SNAT Connection Utilization | The percentage of the maximum SNAT connection capacity currently in use. | Percentage |
| Packets Dropped - SNAT Connection Limit Exceeded | The number of packets dropped because the maximum SNAT connection count was reached. | Count |
| Packets Dropped - EIP Port Allocation Exceeded | The number of packets dropped because all available EIP ports for a given source were exhausted. | Count |
| Packets Dropped - PPS Limit Exceeded | The number of packets dropped because the packets-per-second processing limit was exceeded. | Count |
Threshold configuration
You can configure thresholds and alerts for all NAT metrics to detect performance degradation proactively or connection issues.
- Go to Admin > Configuration Profiles > Threshold and Availability.
- Create or edit your Threshold Profile for NAT.
- Assign the profile to the respective monitors to trigger alerts.
IT Automation
Use Site24x7's IT Automation to resolve common issues with NAT performance:
- Go to Admin > IT Automation Templates. Then, click Add Automation Templates.
- Create an automation rule by selecting the automation Type (e.g., Server reboot, clear queue).
- Map the created rules to the NAT, for automatic execution during alerts.
Configuration rules
Use Configuration Rules to simplify bulk setup across NAT instances. Automatically assign Threshold Profiles, Notification Profiles, Tags, and Monitor Groups when new monitors are discovered.
