As part of our filing for Chapter 11 bankruptcy relief, Akamai has acquired select assets from Edgio, including certain customer contracts from our content delivery, applications, and security businesses, but not including Uplynk. We encourage any active Edgio delivery, applications, or security customers that are not already engaged with Akamai to migrate their services, to contact their local Akamai office or support@edg.io as soon as possible to help avoid service interruptions. Service will end on January 15, 2025.


Any Edgio Uplynk customers can reach out to support@uplynk.com for any questions or concerns.

Log File Naming Convention

RTLD assigns a name to log data stored as an object. Log data is stored as individual objects for the following destinations:
Log data stored within an object is compressed using gzip. Each object follows this naming convention:
[<PREFIX>]<LOG TYPE>_<AN>_<PROFILE ID>_<DATE STAMP>_<AGENT ID>_<SEQUENCE NUMBER>.<FILE EXTENSION>.gz
The JSON document contained within an object follows this naming convention:
[<PREFIX>]<LOG TYPE>_<AN>_<PROFILE ID>_<DATE STAMP>_<AGENT ID>_<SEQUENCE NUMBER>.<FILE EXTENSION>
Sample file name (RTLD CDN - JSON log format): wpc_0001_123_20220111_50550000F98AB95B_1.json
Sample file name (RTLD WAF - JSON log format): waf_0001_123_20220111_50550000F98AB95B_1.json
Sample file name (RTLD Rate Limiting - JSON log format): rl_0001_123_20220111_50550000F98AB95B_1.json
Sample file name (RTLD Bot - JSON log format): bot_0001_123_20220111_50550000F98AB95B_1.json
Sample file name (RTLD Cloud Functions - JSON log format): serverless_0001_123_20220111_50550000F98AB95B_1.json
Each of the above variables are described below.
  • <PREFIX>: You may define a prefix when setting up a log delivery profile. This prefix defines a virtual log file storage location and/or a prefix that will be added to each object added to your bucket.
    • A prefix should not start with a forward slash.
    • A forward slash within the specified prefix is interpreted as a delimiter for a virtual directory.
    • A trailing forward slash means that the specified value only defines a virtual directory path within your bucket where logs will be stored. If the specified value ends in a character other than a forward slash, then the characters specified after the forward slash will be prepended to the file name for each log file uploaded to your destination.
    Sample prefix: logs/CDN/siteA_
    The above prefix will store log files in the following virtual directory: /logs/CDN
    The file name for each log file uploaded to your destination will start with siteA_.
    Sample log file name: siteA_wpc_0001_123_20220111_50550000F98AB95B_1.json
  • <LOG TYPE>: Represents the type of log data.
    • RTLD CDN: This variable is always set to wpc.
    • RTLD WAF: This variable is always set to waf.
    • RTLD Rate Limiting: This variable is always set to rl.
    • RTLD Bot: This variable is always set to bot.
    • RTLD Cloud Functions: This variable is always set to serverless.
  • <AN>: Represents your CDN account number (e.g., 0001).
  • <PROFILE ID>: Represents the system-defined ID for your Real-Time Log Delivery configuration.
    You cannot currently view the system-defined ID assigned to your Real-Time Log Delivery configuration from within the Edgio Console.
  • <DATE STAMP>: Represents the date on which the log file was generated.
    Syntax: YYYYMMDD
    Example: 20230110
  • <AGENT ID>: Represents a unique ID that identifies the Real-Time Log Delivery software agent that generated the log file.
  • <SEQUENCE NUMBER>: Represents a sequential number that identifies the order in which the log file was generated by the software agent identified above.
    Each software agent assigns a sequential number to the log files that it generates. A gap between log files generated on the same day by the same software agent indicates missing log data.

    Key information:
    • This number starts at 0.
    • This number resets to 0 at the start of a new day (UTC).
  • <FILE EXTENSION>: Represents the file extension for the log file. This file extension varies by log format.
    • JSON Log Format: json
    • JSON Array Log Format: json_array
    • JSON Lines Log Format: json_lines
