Understanding the Widgets

The statistics widgets provide a snapshot of key metrics:

1. Cache Hits:

   • Total cache hits versus non-cache hits.
   • A high cache hit rate indicates optimal caching performance.

2. Traffic Breakdown:

   • Plain Traffic: Non-secure traffic (HTTP).
   • HTTPS Traffic: Secure traffic using SSL/TLS.
   • Helps evaluate the proportion of secure vs. non-secure requests.

3. Usage Summary:

   • View Traffic Usage and Cache Usage for the selected period.
   • Overages are marked in red for easy identification.

Graph Insights

The interactive graph plots:

• Average Bandwidth in kbps over time.
• The 95th Percentile, which is a key billing metric in CDN services.
• Use the Reset Zoom feature to focus on specific peaks or periods.

Troubleshooting Tips

1. Cache Efficiency:

   • Review Cache Status Requests to identify low cache hit rates.
   • Adjust caching rules or analyze frequently missed resources for optimization.

2. Traffic Spikes:

   • Use the Bandwidth graph to spot unusual spikes in traffic.
   • Investigate high HTTP status codes (e.g., 5xx errors) under the Status Codes view.

3. Overage Alerts:

   • Monitor the Usage Summary for overage warnings.
   • Adjust your CDN plan or resource allocation accordingly.
