How to install mod-log-firstbyte:
https://code.google.com/p/mod-log-firstbyte/
1. checkout the same project:
# Non-members may check out a read-only working copy anonymously over HTTP.
svn checkout http://mod-log-firstbyte.googlecode.com/svn/trunk/ mod-log-firstbyte-read-only
2. readme file:
Compile and install the module using apxs2, e.g.
apxs2 -c mod_log_firstbyte.c
apxs2 -i -a mod_log_firstbyte.la
This will add a line to your configuration file to load the module:
LoadModule log_firstbyte_module /path/to/mod_log_firstbyte.so
The module adds a new option to your log format string: '%F'. This is the request-to-first-byte time, in microseconds. Edit your configuration files to include a new LogFormat directive. I usually use:
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %D %F" combined-with-firstbyte
###### My custom with epoch time too ######
LogFormat "%{%s}t %D %F %h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" " combined-with-firstbyte
%D The time taken to serve the request, in microseconds.
Sample output:
<epoch> <%D> <%F> => 1389809102 1471 1080
1389809102 1471 1080 127.0.0.1 - - [15/Jan/2014:18:05:02 +0000] "GET /server-status?auto HTTP/1.1" 200 373 "-" "libwww-perl/6.03"
######## End of My custom log #####
Finally, change the CustomLog directive:
CustomLog /var/log/apache2/access.log combined-with-firstbyte
3. Install the following cheks:
sudo apt-get install apache2-prefork-dev
sudo apt-get install apache2-threaded-dev
4.
sudo apxs2 -c mod_log_firstbyte.c
sudo apxs2 -i -a mod_log_firstbyte.la
5. After updating the config files [2] restart the apache.

Libraries have been installed in:
/usr/lib/apache2/modules
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
chmod 644 /usr/lib/apache2/modules/mod_log_firstbyte.so
