# Overview Dashboard

The **Overview Dashboard** provides a unified snapshot of your CDN performance.\
It consolidates traffic, cache, and error metrics into a single visual interface — helping you quickly identify patterns, detect regional issues, and assess your content delivery health across all resources.

Use this dashboard as your starting point before exploring deeper analytics such as **Performance** or **Cache Analytics**.

{% hint style="info" %}
Use it as your starting point to assess overall CDN health and efficiency before exploring detailed dashboards such as Performance Analytics or Cache Analytics.
{% endhint %}

### 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.

<figure><img src="/files/PgluRt3CZXQdkvmywp9J" alt=""><figcaption><p>Top Metrics</p></figcaption></figure>

<table><thead><tr><th width="351">Metric</th><th>Description</th></tr></thead><tbody><tr><td><strong>Total Counts</strong></td><td>Total number of CDN requests.</td></tr><tr><td><strong>Total Bytes</strong></td><td>Total amount of data transferred.</td></tr><tr><td><strong>HIT Ratio</strong></td><td>Percentage of requests served from cache.</td></tr><tr><td><strong>Error Ratio</strong></td><td>Percentage of requests resulting in 4xx–5xx errors.</td></tr></tbody></table>

These key figures automatically update when filters are applied.

{% hint style="info" %}
Regularly compare **HIT Ratio** and **Error Ratio** to ensure cache improvements are not introducing delivery errors.
{% endhint %}

### Traffic Distribution

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

<figure><img src="/files/2uOcTVr72SxdGv0UPmte" alt=""><figcaption><p>Traffic Distribution</p></figcaption></figure>

* **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.

{% hint style="info" %}
Use the **Metric** filter to switch between *Requests* and *Data Transferred* — this changes all traffic distribution visualizations instantly.
{% endhint %}

### Cache Efficiency

Understand how effectively your CDN edge nodes serve cached content.

<figure><img src="/files/ncItGn8R0spARG6yaTrB" alt=""><figcaption><p>Cache Efficiency</p></figcaption></figure>

* **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.

{% hint style="info" %}
If your **HIT Ratio** drops in a specific country, check Page Rules and TTL settings — short TTLs often reduce cache efficiency.
{% endhint %}

### Error Analytics

Monitor request health and troubleshoot delivery issues:

<figure><img src="/files/qYPEs25OgU06CRGntF6r" alt=""><figcaption><p>Error Analytics</p></figcaption></figure>

* **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.

{% hint style="info" %}
If you see persistent 4xx or 5xx spikes in specific regions, check recent **Purge** or **Origin configuration** changes in your [Medianova Control Panel](https://cloud.medianova.com).
{% endhint %}

### **Filters**

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

<table><thead><tr><th width="364">Filter</th><th>Description</th></tr></thead><tbody><tr><td><strong>Resource</strong></td><td>Select a specific CDN resource.</td></tr><tr><td><strong>Account Type</strong></td><td>Filter by resource category.</td></tr><tr><td><strong>Country</strong></td><td>Focus on traffic from specific locations.</td></tr><tr><td><strong>Status</strong></td><td>Show only selected HTTP status codes.</td></tr><tr><td><strong>Hit Status</strong></td><td>Filter by cache result (HIT, MISS, etc.).</td></tr><tr><td><strong>Metric</strong></td><td>Switch between <em>Requests</em> and <em>Data Transferred</em>.</td></tr></tbody></table>

{% hint style="info" %}
Filters can be combined — for example, **Resource + Country** — to focus on specific CDN behavior in a region.
{% endhint %}

### **FAQ**

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

**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.

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