Class AccessLogFormatParser

java.lang.Object

io.micronaut.http.server.netty.handler.accesslog.element.AccessLogFormatParser

public class AccessLogFormatParser
extends java.lang.Object

The access log format parser. The syntax is based on Apache httpd log format. Here are the supported directives:

• %a - Remote IP address
• %A - Local IP address
• %b - Bytes sent, excluding HTTP headers, or '-' if no bytes were sent
• %B - Bytes sent, excluding HTTP headers
• %h - Remote host name
• %H - Request protocol
• %{
  }i - Request header. If the argument is omitted (%i) all headers will be printed
• %{
  }o - Response header. If the argument is omitted (%o) all headers will be printed
• %{}C - Request cookie (COOKIE). If the argument is omitted (%C) all cookies will be printed
• %{}c - Response cookie (SET_COOKIE). If the argument is omitted (%c) all cookies will be printed
• %l - Remote logical username from identd (always returns '-')
• %m - Request method
• %p - Local port
• %q - Query string (excluding the '?' character)
• %r - First line of the request
• %s - HTTP status code of the response
• %{}t - Date and time. If the argument is ommitted the Common Log Format format is used ("'['dd/MMM/yyyy:HH:mm:ss Z']'"). If the format starts with begin: (default) the time is taken at the beginning of the request processing. If it starts with end: it is the time when the log entry gets written, close to the end of the request processing. The format should follow the DateTimeFormatter syntax.
• %u - Remote user that was authenticated. Not implemented. Prints '-'.
• %U - Requested URI
• %v - Local server name
• %D - Time taken to process the request, in millis
• %T - Time taken to process the request, in seconds

In addition, the following aliases for commonly utilized patterns:

• common - %h %l %u %t "%r" %s %b Common Log Format (CLF)
• combined - %h %l %u %t "%r" %s %b "%{Referer}i" "%{User-Agent}i" Combined Log Format
