• verbose: Log to STDOUT when it rotates files and name of log file. Default false.
• date_format: Format used to attach dates to file names. Default YYYY-MM-DD.

Examples

Configured as global prefilter

All request to any provider will be stored:

{
  "prefilters" : [
    {
      "id" : "global-log",
      "path" : "clydeio-simple-access-log",
      "config" : {
        "directory" : "./tmp/log",
        "file" : "global-access-%DATE%.log"
      }
    }
    ...
  ]
}

Configured as provider prefilter

Only the requests addresses to the provider will be stored

{
  "providers" : [
    {
      "id" : "some_provider",
      "context" : "/some_provider",
      "target" : "http://some_server",
      "prefilters" : [
        {
          "id" : "provider-logger",
          "path" : "clydeio-simple-access-log",
          "config" : {
            "directory" : "./tmp/log",
            "file" : "provider-access-%DATE%.log"
          }
        }
    },
    ...
  ]
}

Notes

• Note if you configure as a postfilter it is only invoked for success responses.
