# Monitoring

## **Overview** <a href="#tong-quan" id="tong-quan"></a>

The vCDN system supports customers to monitor and track all CDN service operations via **Portal** or **API** , providing detailed, intuitive information about service performance and status.

The metrics will be visually provided in Dashboards and charts with:

* Data is updated **every minute** .
* Maximum delay is **5 minutes** (near realtime), helping customers promptly grasp changes in the system.

## Detail <a href="#chi-tiet" id="chi-tiet"></a>

The types of charts/reports we provide you include:

* **Traffic Consuming:** total bandwidth used on the CDN system in a month.
* **Origin Request/s** : number of requests sent from CDN to Origin per second.
* **Origin Traffic Consuming/s (GB/s)** : traffic consumed from Origin, measured in GB per second.
* **Unique IPs:** Displays the number of unique IPs sending requests to the CDN system.
* **Origin Speed/s:** real-time download and serving speed from Origin.
* **Average User Speed:** Average download speed from Origin to CDN over a period of time.
* **Hit Cache Ratio:** Percentage of requests served from the CDN cache instead of the Origin.
* **Request Content Type:** Classifies the requested content types (e.g. HTML, CSS, JS, images, videos).
* **CDN HTTP Codes, Origin HTTP Codes:** Track the connection status between CDN and Origin (success, 4xx error, 5xx error...).
* **Manage and monitor signals pushed to the Live Entry point system**
