Display Apache Server Status with mod_status

by Vivek Gite on June 6, 2008 · 7 comments

Q. How do I display Apache server status such as current server activity and performance under Red Hat Enterprise Linux / UNIX / BSD?

A. You can use regular Linux / UNIX commands such as lsof, netstat, top, vmstat and others to view apache server activity, status and performance from a shell prompt. However, I recommend mod_status because it provides good information about Apache server.

mod_status Apache module

There is also mod_status built into Apache web server to get server status from a web browser. With this module you can easily find out how well your server is preforming. All reports are generated in a html format. You can easily find out following type of information:

Total number of worker serving requests
Total number of of idle worker
Find the status of each worker, the number of requests that worker has performed and the total number of bytes served by the worker
Total number byte count served
Other information such as CPU usage, number of requests per second,current hosts and requests being processed etc.

How do I configure mod_status to display Apache web server status?

Open your httpd.conf / apache2.conf file:
# vi httpd.conf
Fnd out (append line) that read as follows to allow access from 10.1.2.5 only:

<Location /server-status>
   SetHandler server-status
   Order Deny,Allow
   Deny from all
   Allow from 10.1.2.5
</Location>

You can also restrict access using a domain name:

<Location /server-status>
   SetHandler server-status
   Order Deny,Allow
   Deny from all
   Allow from w1.g2.dc3.helpdesk.nixcraft.com
</Location>

Save and close the file. Restart web server, enter:
# service httpd restart
Fire a webbrowser and type the url http://your-server-ip/server-status or http://your-corp.com/server-status

Hi,

An undocumented or obscurely documented feature,
appending “?notable” to the status url, like;
http://your-server-ip/server-status?notable
gives you a different output.

I have server-status working fine using http:/servername/server-status
How can I output this to a text file?

6 Pico March 22, 2011

You can use wget command to output to a file, try :

/usr/bin/wget –quiet -O – “http:/servername/server-status” > Output.txt

7 APCTL July 20, 2011: [wget ... -O - ... > Output.txt] ??
Whats wrong with:
[wget ... -O Output.txt ... ] ?
