You can set values for Google Analytics <a href=":custom_var_documentation">Custom Dimensions</a> here. You must have already configured your custom dimensions in the <a href=":setup_documentation">Google Analytics Management Interface</a>. You may use tokens. Global and user tokens are always available; on node pages, node tokens are also available. A dimension <em>value</em> is allowed to have a maximum length of 150 bytes. Expect longer values to get trimmed.
