Overview Dashboard

Learn how to monitor overall CDN traffic, cache ratio, and error trends in the Overview Dashboard.

The Overview Dashboard brings together your most important CDN metrics in a single, unified view. It helps you visualize global performance trends, identify high-traffic regions, and evaluate cache and error ratios across all resources.

Overview Dashboard

Use it as your starting point to assess overall CDN health and efficiency before exploring detailed dashboards such as Performance Analytics or Cache Analytics.

1

Top Metrics

At the top of the dashboard, you’ll find four summary indicators that provide a quick snapshot of your CDN activity for the selected time range.

Metric	Description
Total Counts	Total number of CDN requests.
Total Bytes	Total amount of data transferred.
HIT Ratio	Percentage of requests served from cache.
Error Ratio	Percentage of requests resulting in 4xx–5xx errors.

These key figures automatically update when filters are applied.

Compare HIT Ratio and Error Ratio regularly to ensure cache performance improvements do not coincide with higher error rates.

2

Traffic Distribution

Visualize where your content is delivered and which resources or countries generate the most requests.

• Requests per Resource (bar chart): Displays total requests or data transfer by CDN resource.

• Requests per Country (pie chart): Shows top ten countries by traffic share.

These charts help you understand traffic concentration across your infrastructure.

Use the Metric filter to switch between Requests and Data Transferred — this changes all traffic distribution visualizations instantly.

3

Cache Efficiency

Understand how effectively your CDN edge nodes serve cached content.

• Top Resources HIT Ratio (gauge): Cache hit percentage for top five resources.

• Top Countries HIT Ratio (gauge): Cache hit percentage for top five countries.

Compare these metrics to identify where cache optimization is most effective.

If your HIT Ratio drops in a specific country, check Page Rules and TTL settings — short TTLs often reduce cache efficiency.

4

Error Analytics

Monitor request health and troubleshoot delivery issues:

• Status Counts (time series): Shows requests per HTTP status code (2xx, 3xx, 4xx, 5xx).

• Overview Table: Provides per-resource and per-country breakdown of total requests, data transferred, HIT ratio, and error ratio.

If you see persistent 4xx or 5xx spikes in specific regions, check recent Purge or Origin configuration changes in your Medianova Control Panel.

Filters

You can customize all dashboard visualizations by applying filters. Each filter updates charts, tables, and metrics in real time.

Filter	Description
Resource	Select a specific CDN resource.
Account Type	Filter by resource category.
Country	Focus on traffic from specific locations.
Status	Show only selected HTTP status codes.
Hit Status	Filter by cache result (HIT, MISS, etc.).
Metric	Switch between Requests and Data Transferred.

Filters can be combined — for example, Resource + Country — to focus on specific CDN behavior in a region.

FAQ

Q1: Can I compare multiple resources at once? Yes. Use the Resource filter to select multiple resources, and all charts will display combined metrics.

Q2: Why does my HIT ratio drop suddenly? This often happens after new content is published or cache rules change. Check recent purge operations or cache expiration settings.

Q3: What time range does the dashboard support? The default range is 24 hours, but you can expand it based on your dataset retention settings.
