Re: Logging

I don't know of any good way to configure one log file per process. Instead,
consider using a single log file (like you are now) and define your logging
format so that it contains a process identifier of some kind (e.g. PID). If
you are running on a Unix-like OS, you can then use the various command-line
tools (e.g. awk, grep) to filter out the messages for a particular process
if needed. With this approach, by default you have an aggregate view of the
logs but it is also easy to view the logs by process (I find myself needing
to do both on occasion). Plus, it is less cumbersome (IMO) to have a single
log file than 50.

 

BTW, if you are deploying to a Windows machine, you can still use awk, grep,
etc. to filter the logs; just install Cygwin (www.cygwin.com
<http://www.cygwin.com/> ).

Subject: [FASTCGI] Logging

 

Hi all,

I have a fastcgi based service with Apache 2.2 with the configuration
bellow.

I am facing logging problems because all 50 processes write to the same file
(error_log) and the messages are mixed.

Is there any configuration in order to have one log file per each fast-cgi
process?

Httpd.conf

ErrorLog "logs/error_log"
LoadModule fastcgi_module modules/mod_fastcgi.so
<IfModule mod_fastcgi.c>
    Alias /fcgi-bin/ /app/onlinec/applon/exe/
    <Directory /app/onlinec/applon/exe>
      AllowOverride None
      Allow from all
    </Directory>
    #
    # Start a "static" server at httpd initialization inside the scope of
the SetHandler
    #
    FastCgiServer /app/onlinec/applon/exe/elag -processes 50 -idle-timeout
180 -restart-delay 5 -initial-env LD_PRELOAD=/usr/lib/[email protected] -initial-env
NLS
_LANG=AMERICAN_AMERICA.WE8ISO8859P1 -initial-env
LD_LIBRARY_PATH=/usr/openwin/lib:/app/fcgi/lib:/app/oracle/instclient
-initial-env DBCONNECT=XXXXX/XXXXX@XXXXX:####/XXXXX -initial-env
ENVFILE=/app/onlinec/resources/config/applon.env
    #
    LogFormat "%P %t %>s %T %a %B \"%r\"" common
    CustomLog logs/access_log common
</IfModule>

Best regards,
