Enable httpd fullstatus to Monitor Apache Status

[jominj]

Apache has built in utilities that help’s  a  administrator to monitor the performance and activity of their web server. The Apache Status is one such tool that allows real time monitoring of Apache connections and resource usage.

The Apache Status provides  information that will help in performance monitoring and Apache tuning. The Apache module mod_status  is required to enable apache status . Mod_status will provide the following information to the viewer:

• The number of worker serving requests
• The number of idle worker
• The time the server was started/restarted and the time it has been running.

The status module can also be set to an extended mode, which will display additional information like:

• The status of each worker, the number of requests that worker has performed and the total number of bytes served by the worker
• A total number of accesses and byte count served
• The current CPU used in % by each worker and in total by Apache
• The current hosts and requests being processed

To set the handler, open the  Apache config file /etc/httpd/conf/httpd.conf  and search for the following block:

Code: [Select]

#<Location /server-status>

#Order deny,allow
#Deny from all
#Allow from .example.com
#</Location>Un-Comment the  above lines  ::

Code: [Select]

<Location /server-status>
 SetHandler server-status
 Order deny,allow
 Deny from all
 Allow from 127.0.0.1
 </Location>Save  the changes and restart  the apache service
Enable Extended Status in Apache
Open  the httpd.conf file and search  for the line:
#ExtendedStatus On
