Preface

    This manual will explore every aspect of installing, managing, extending, and troubleshooting Traffic Server.

    This documentation uses the following typographic conventions:

    Italic

    Used to introduce new terms on their initial appearance.

    • Example:

      The Apache Traffic Server™ object storage is based on a cyclone buffer architecture. Cyclone buffers are a form of storage addressing in which a single writer continually reclaims the oldest allocations for use by new updates.

    Monospace

    Represents C/C++ language statements, commands, file paths, file content, and computer output.

    Represents variables for which you should substitute a value in file content or commands.

    • Example:

      Running the command traffic_ctl metric get <name> will display the current value of a performance statistic, where is the statistic whose value you wish to view.

    Ellipsis

    Indicates the omission of irrelevant or unimportant information.
