I have a apache server running on CentOS 6.5 server. In log files 25% of records are like this
000.000.000.000 - - [24/Jul/2014:04:15:10 +0000] "GET /address/of/the/page.html HTTP/1.1" 200 20341 "-" "Mozilla/4.0
But rest of 75% of logs are like this, without IP
- - [24/Jul/2014:04:15:10 +0000] "GET /address/of/the/page.html HTTP/1.1" 200 20341 "-" "Mozilla/4.0
Can somebody tell me what is the problem?
Thanks!
By default Apache prints the REMOTE_ADDR header value in the access log, it may be that in your environment that value is blank in some cases. You can try printing the X-Forwarded-For header in the access log and see if that has the values that you need.
Typically if the requests are passing through proxy servers/load balancers its a good idea to check the value of the XFF header for the correct client IP.
Hope this help.

Complementing Avi's response, you will need to open the file /etc/apache2/apache2.conf and change the following lines:
LogFormat "%v:%p %h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" vhost_combined
LogFormat "%h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" combined
LogFormat "%h %l %u %t \"%r\" %>s %O" common
LogFormat "%{Referer}i -> %U" referer
LogFormat "%{User-agent}i" agent
to:
LogFormat "%{X-Forwarded-For}i %v:%p %h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" vhost_combined
LogFormat "%{X-Forwarded-For}i %h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" combined
LogFormat "%{X-Forwarded-For}i %h %l %u %t \"%r\" %>s %O" common
LogFormat "%{X-Forwarded-For}i %{Referer}i -> %U" referer
LogFormat "%{X-Forwarded-For}i %{User-agent}i" agent
Then, restart apache service with the command: sudo service apache2 restart
and the client ip will appear on apache log.
Check the result with:
cat /var/log/apache2/access.log

I try to modify the error log to show runtime duration.
I added %T/%D at the end of the LogFormat at httpd.conf
like this:
<IfModule log_config_module>
LogFormat "%{Referer}i -> %U" referer
LogFormat "%{User-agent}i" agent
# NOTE: "combined" and "common" are required by WHM
LogFormat "%h %l %u %t \"%r\" %>s %b" common
LogFormat "%T%D %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %T/%D" combined
# access_log format can be set in WHM under 'Basic cPanel & WHM Setup'
CustomLog logs/access_log combined
</IfModule>
I restarted the httpd service but the change didn't take place.
At Cpanel it is specified to use the combined format.
Can someone help me please?

We are using the above log4j.properties to create web logs and api logs.
web related logs goes to web/manual.log.
api related logs goes to api/manual.log.
api security related logs goes to apiSecurity/manualSecurity.log
for api manual.log and log4j-app.log files are creating as
manual.log, manual.log.1, manual.log.2 ...etc.,
log4j-app.log, log4j-app.log.1, log4j-app.log.2 ... so on.
I want all the log details in a single file as manual.log and log4j-app.log, please let me know how to get it?
Appenders type needs to be changed from RollingFileAppender to FileAppender.
So after changing it, your log4j.properties would look like:

I have built a custom OpenSSL engine which will offload RSA decryption operation to GPU.
The engine requires each incoming request to be handled by a thread.
As request comes, its data will be placed in a buffer and will be offloaded to GPU once the buffer threshold is exceeded.
To test this engine, I am using Apache server with Worker MPM enabled.
To generate concurrent client requests, I am utilizing Apache benchmark tool.
Ideally, when concurrent requests are issued, each requests will be handled by a server thread, and the buffer will be filled up with data from all the requests.
However, when tested, the buffer only contains data from 1 request.
I would appreciate if anybody can explain why only single thread is utilizing my engine?
Below is the listing of httpd.conf file
#
# This is the main Apache HTTP server configuration file. It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs/2.4/> for detailed information.
# In particular, see
# <URL:http://httpd.apache.org/docs/2.4/mod/directives.html>
# for a discussion of each configuration directive.
#
# Do NOT simply read the instructions in here without understanding
# what they do. They're here only as hints or reminders. If you are unsure
# consult the online docs. You have been warned.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path. If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "logs/access_log"
# with ServerRoot set to "/usr/local/apache2" will be interpreted by the
# server as "/usr/local/apache2/logs/access_log", whereas "/logs/access_log"
# will be interpreted as '/logs/access_log'.
#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path. If you point
# ServerRoot at a non-local disk, be sure to specify a local disk on the
# Mutex directive, if file-based mutexes are used. If you wish to share the
# same ServerRoot for multiple httpd daemons, you will need to change at
# least PidFile.
#
ServerRoot "/usr/local/apache2_mpmWorker"
#
# Mutex: Allows you to set the mutex mechanism and mutex file directory
# for individual mutexes, or change the global defaults
#
# Uncomment and change the directory if mutexes are file-based and the default
# mutex file directory is not on a local disk or is not appropriate for some
# other reason.
#
# Mutex default:logs
#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses.
#
#Listen 12.34.56.78:80
Listen 80

With RHEL and Apache (httpd), is there a way to:
Detect which v.host (domain) is gaining how many incoming connections?
Because in this few days, i got a lot of incoming connections on the Server being acknowledged by using:
ps aux | grep httpd -c
734
That means i have 734 incoming connections currently being handled by Apache but the problem is i have (lets say) 10 Vhosts (domains).
So which Domain is getting the high loads?
Any sharp solutions please.
Say you have a file like /etc/apache2/sites-enabled/000-example.com
You may see lines like:
<VirtualHost *:80>
ServerName www.example.com
ServerAlias example.com
DocumentRoot /www/example.com
Further down, If you want, you can create logfiles for each VirtualHost by changing lines
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
Too:
ErrorLog ${APACHE_LOG_DIR}/example_com.error.log
CustomLog ${APACHE_LOG_DIR}/example_com.access.log combined
Otherwise, if you don't want to create logfiles for each VirtualHost, then you can create your own custom log format http://httpd.apache.org/docs/2.2/mod/mod_log_config.html#formats
For example:
LogFormat "%v %h %l %u %t \"%r\" %>s %b" common
CustomLog ${APACHE_LOG_DIR}/access.log common
When you have decided how you want to log, then you can write all kinds of scripts to examine or compare your logs. It would be far easier if you are using separate logfiles for each virtualhost, because you may try this.
wc -l /var/log/apache2/*access.log
When I don't specify a logfile in the virtual host sections of my conf-file the logs are written in the file specified in httpd.conf (=access_log).
A log-entry would look like this:
SOMEIP - - [22/Jan/2013:18:34:08 +0100] "GET / HTTP/1.1" 200 1752 "-" "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/SOMEIP Safari/537.17"
SOMEIP - - [22/Jan/2013:18:34:08 +0100] "GET /img/homepage_bg.png HTTP/1.1" 304 - "http://DOMAIN/" "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.17 (KHTML, like Gecko) C$
But when I define a log file in the virtual host section the new log file contains different information:
SOMEIP - - [22/Jan/2013:18:33:34 +0100] "GET / HTTP/1.1" 200 1752
SOMEIP - - [22/Jan/2013:18:33:34 +0100] "GET /img/homepage_bg.png HTTP/1.1" 304 -
i define the log file like this:
CustomLog logs/DOMAIN-access_log common
Why does a custom log contain less information than the general log where all virtual hosts log in by default?
You need to define the alias "common" with a log format that includes the user-agent.
LogFormat "%h %l %u %t \"%r\" %>s %b "%{User-agent}i" common
You didn't say what flavour of Linux you're using. Any decently configured Apache (for example the Debian-based ones like Ubuntu, Mint, etc.) will already have a fitting LogFormat containing the user-agent in their configuration. Look for all the lines matching LogFormat. You should find something like this:
LogFormat "%v:%p %h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" vhost_combined
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined
LogFormat "%h %l %u %t \"%r\" %>s %b" common
LogFormat "%{Referer}i -> %U" referer
LogFormat "%{User-agent}i" agent
Just use the combined or even the vhost_combined parameter for your logfile:
CustomLog logs/DOMAIN-access_log combined
You should also look at the documentation for the Custom Log Formats.
