# Access Logs

## Introduction

Access Logs for CDN is a paid feature that can be used to display all access requests made per instance/domain to the CDN in the specified period.&#x20;

It initially displays the exact date and time of the request (with the time zone as specified in the date picker), the requested domain, the requested URL (location), the IP of the client, the User Agent, the cache status of the requested content, and the HTTP status code.&#x20;

By expanding the log entry, additional data is displayed, including the requested CDN node, the amount of bytes transferred from CDN to client, the request processing time, the HTTP request method, and the protocol and TLS version used.

In the top left, it can be specified which instances and for which period of time access logs should be displayed. Below, there is also a search bar for specific queries.

The retention period for Access Logs is seven days. It is possible to export the access logs for the specified instance and time period as a CSV file.

* **MISS**: The resource was not found in the CDN cache, or the cache age was expired. The resource was requested from the origin.

**HTTP-Status Code:** Status of request (200/3XX/4XX/5XX)
