How to Monitor Elastic Load Balance in Huawei Cloud
Site24x7 offers monitoring support for Huawei Cloud's Elastic Load Balance (ELB) service. Monitoring the performance and health of your Huawei ELB, which distributes incoming traffic across multiple backend servers to ensure high availability and fault tolerance.
Use cases
- Ensure application availability: Monitor connections per second and inbound bandwidth to identify sudden traffic surges.
- Detect drops: Track dropped connections and blocked traffic to identify network issues or security rules blocking legitimate requests.
- Capacity planning: Analyze active connections and L4 connection usage to understand how much load the ELB is handling.
Setup and configuration
ELB 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 ELB from the Service/Resource Types drop-down menu and click Save.
- Go to Cloud > Huawei. Then, select the created Huawei monitor.
- Click ELB to view the performance metrics.

Threshold configuration
You can configure thresholds and alerts for all ELB metrics to detect performance degradation proactively or connection issues.
- Go to Admin > Configuration Profiles > Threshold and Availability.
- Create or edit your Threshold Profile for ELB.
- Assign the profile to the respective monitors to trigger alerts.
IT Automation
Use Site24x7's IT Automation to resolve common issues with ELB 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 ELB, for automatic execution during alerts.
Configuration rules
Use Configuration Rules to simplify bulk setup across ELB instances. Automatically assign Threshold Profiles, Notification Profiles, Tags, and Monitor Groups when new monitors are discovered.
