Apache Module mod_logio

+
+

Available Languages:  en  | + fr  | + ja  | + ko  | + tr 

+
+ + + +
Description:Logging of input and output bytes per request
Status:Extension
Module Identifier:logio_module
Source File:mod_logio.c
+

Summary

+ + +

This module provides the logging of input and output number of + bytes received/sent per request. The numbers reflect the actual bytes + as received on the network, which then takes into account the + headers and bodies of requests and responses. The counting is done + before SSL/TLS on input and after SSL/TLS on output, so the numbers + will correctly reflect any changes made by encryption.

+ +

This module requires mod_log_config.

+ +
When KeepAlive connections are used with SSL, the overhead of the SSL + handshake is reflected in the byte count of the first request on the + connection. When per-directory SSL renegotiation occurs, the bytes are associated + with the request that triggered the renegotiation.

Custom Log Formats

+ + +

This module adds three new logging directives. The characteristics of the + request itself are logged by placing "%" directives in + the format string, which are replaced in the log file by the values as + follows:

+ + + + + + + + + + + +
Format StringDescription
%IBytes received, including request and headers, cannot be + zero.
%OBytes sent, including headers, cannot be zero.
%SBytes transferred (received and sent), including request and headers, + cannot be zero. This is the combination of %I and %O.
+ Available in Apache 2.4.7 and later
%^FBDelay in microseconds between when the request arrived and the + first byte of the response headers are written. Only available if + LogIOTrackTTFB is set to ON.
+ Available in Apache 2.4.13 and later
+ +

Usually, the functionality is used like this:

+ +
+
Combined I/O log format:
+
"%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" + \"%{User-agent}i\" %I %O"
+

LogIOTrackTTFB Directive

+ + + + + + + + + +
Description:Enable tracking of time to first byte (TTFB)
Syntax:LogIOTrackTTFB ON|OFF
Default:LogIOTrackTTFB OFF
Context:server config, virtual host, directory, .htaccess
Override:All
Status:Extension
Module:mod_logio
Compatibility:Apache HTTP Server 2.4.13 and later
+

This directive configures whether this module tracks the delay + between the request being read and the first byte of the response + headers being written. The resulting value may be logged with the + %^FB format.
