Raw Log File Storage

Basic log data is automatically archived on our servers. As a result, you will always be able to access basic information about your CDN activity data through the Core Reports module. Core reports are available by finding Analytics from within the main menu and then selecting Core Reports. However, you may wish to store more detailed log information or use a third-party tool to analyze your log data. For this reason, we allow you to store log information on CDN storage and/or to deliver them directly to your servers.

Key information:

• Log files are not stored on CDN or customer storage by default.

  Retain this data by performing the following steps: 

  1. Enable raw log file archival to CDN storage.

     1. Turn on raw log file storage.
     2. Enable it for each desired platform.
     3. Define the length of time that raw log files will be retained on CDN storage under the Please keep log files for option.

  2. Determine whether raw log files will also be stored on your own server.

     A prerequisite for archiving raw log files to your own server is enabling raw log file archival to CDN storage. If this is undesired, the length of time that raw log files will be stored on CDN storage can be minimized by setting the retention period to 1 day.

• If you are unable to enable log file storage, then your account has been configured to track CDN traffic through a logless system. Platforms that have been assigned to a logless system will also be unable to take advantage of other log-dependent features, such as the following reporting modules: Advanced Content Analytics and Edge Performance Analytics. For more information, please contact your CDN account manager.
• Raw log file archival and retention options can be found on the Raw Log Settings page.
• Raw log files archived to CDN storage will be stored in a folder called "Logs." This folder is located off the root folder of CDN storage.
• View information on the file naming convention for archived raw log files.
• Archived raw log files can be accessed like all other content stored on CDN storage. Use your preferred SFTP client to download this data.
• Your account will be billed for the amount of disk space used on CDN storage. For a detailed explanation of account billing, please contact your CDN account manager.

To configure log storage options

1. Navigate to the Raw Log Settings page.

2. Perform one of the following:

   • Enable Log Storage: Perform the following steps:

     1. Select the Log storage is turned on option.
     2. Mark each platform for which you would like to store log data.
     3. Clear each platform for which log data will be discarded.

     4. In the Please keep log files for option, select the amount of time that the log files for each selected platform should be kept.

        If you choose "unlimited," then log files will not be automatically deleted from the CDN origin server.

   • Disable Log Storage: Select the Log storage is turned off option.
3. Click Update to save your changes.

External Storage

In addition to storing log data on CDN storage, it may also be delivered to your web server via SFTP. Additionally, opt-in to receive email notifications whenever a log file cannot be delivered to your web server.

Due to the security risks inherent to FTP (e.g., authentication via cleartext passwords), log delivery over FTP was discontinued. You may only authenticate a user through a password or a RSA private key.

A prerequisite for archiving raw log files to your own server is enabling raw log file archival to CDN storage. If this is undesired, the length of time that raw log files will be stored on CDN storage can be minimized by setting the retention period to 1 day.

To configure log file delivery settings

1. Navigate to the Raw Log Settings page.

2. Verify that raw log file storage has been enabled for the desired platforms.

3. Perform one of the following:

   • Enable Log Delivery: Archive log files to an external server by selecting the Enabled option from the FTP and SFTP Delivery Settings section.
   • Disable Log Delivery: If log files should not be archived to an external server, then make sure that the Disabled option is selected from the FTP and SFTP Delivery Settings section and then click Update. Skip all remaining steps.
4. In the Log Delivery Type option, verify that SFTP is selected.
5. In the Port option, select the port to which log data will be sent.
6. In the Notification E-mail option, type the email address to which an email will be sent when a log file is not successfully delivered to the specified external server.

7. In the Hostname option, type the hostname or IP address of the server where log files will be archived.

   Make sure to exclude protocol information (i.e., sftp://).

8. In the Directory Path option, type the path to the folder where log files will be archived. This path starts at the root folder of the server specified in the previous step.

   Make sure to start this path with a forward slash (e.g., /Logs).

9. In the Username option, type the name of the user that has SFTP access to the specified server.

   Make sure that the specified user has been granted read/write to the folder defined in the Directory Path option.

10. Determine whether the above user will be authenticated via a password or a RSA private key.

    • Password Authentication: In the Password option, type the password associated with the specified user account.

    • Private Key Authentication: Perform the following steps:

      1. Paste the desired RSA private key into the Private Key Text option.
      2. Make sure that the same private key is stored in the home directory assigned to the user specified in the Username option.
11. Click Update to save the updated configuration.

12. Configure your firewall to allow access to the following subnetworks:

    93.184.209.128/25

    192.16.62.0/25

    192.16.61.128/25

    192.229.176.0/24
