How to Monitor Content Delivery Network in Huawei Cloud
Site24x7 monitors Huawei Cloud's Content Delivery Network (CDN) metrics, delivering insights into bandwidth, traffic, request rates, cache performance, latency, and HTTP status codes. These insights help you detect issues early and ensure reliable content delivery.
Use cases
Cache efficiency: Enhance performance by monitoring cache hit rates and traffic patterns, allowing for lower load on the origin server and preventing increases in latency.
Origin stability: Identify origin failures early by tracking 5xx error rates and the frequency of requests returned to the source, enabling swift recovery before users experience any interruptions.
Error visibility: Safeguard user experience by monitoring HTTP error rates to distinguish between client-side and server-side issues, enabling quicker resolution.
Setup and configuration
Content Delivery Network resources are auto-discovered and monitored during the Huawei Cloud integration. To enable monitoring, follow the steps below:
- Navigate to Cloud > Huawei > Add Huawei Monitor. Learn how to add a Huawei Cloud monitor.
- While adding or editing a Huawei Cloud monitor, select CDN from the Service/Resource Types drop-down and click Save.
- Navigate to Cloud > Huawei, select the created Huawei monitor, and then click CDN.

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