Changing log placement

  Last updated 2023-09-28

Fastly's Real-Time Log Streaming feature allows you to specify where the logging call should be placed in the generated VCL.

Available log placement options

You can choose one of the following log placement options:

  • Format Version Default puts the log statement in vcl_log if the logging endpoint is using version 2 log format. If the logging endpoint is using version 1 log format, puts the log statement in vcl_deliver.
  • None prevents the log statement from being rendered in VCL. Use this option if you intend to write a log statement manually in custom VCL.
