The Status Module is only available in Apache 1.1 and later.
The Status module allows a server administrator to find out how well
their server is performing. A HTML page is presented that gives
the current server statistics in an easily readable form. If required
this page can be made to automatically refresh (given a compatible
browser). Another page gives a simple machine-readable list of the current
The details given are:
A compile-time option must be used to display the details marked "(*)" as
the instrumentation required for obtaining these statistics does not
exist within standard Apache.
- The number of children serving requests
- The number of idle children
- The status of each child, the number of requests that child has
performed and the total number of bytes served by the child (*)
- A total number of accesses and byte count served (*)
- The time the server was started/restarted and the
time it has been running for
- Averages giving the number of requests per second,
the number of bytes served per second and the average number
of bytes per request (*)
- The current percentage CPU used by each child and in total by
- The current hosts and requests being processed (*)
Enabling Status Support
To enable status reports only for browsers from the foo.com
domain add this code to your
access.conf configuration file
<Limit GET POST>
deny from all
allow from .foo.com
You can now access server statistics by using a Web browser to access the
You can get the status page to update itself automatically if you have
a browser that supports "refresh". Access the page
http://your.server.name/server-status?refresh=N to refresh the page
every N seconds.
Machine Readable Status File
A machine-readable version of the status file is available by accessing the
http://your.server.name/server-status?auto. This is useful
when automatically run, see the Perl program in the
directory of Apache,
To obtain full statistics you must compile Apache with a special
directive. On some machines there may be a small performance loss
if you do this. Try full statistics and see if you notice any
difference. If you do please contact
email@example.com and tell me your configuration.
Do this by adding the following to the AUX_CFLAGS line in the
"Configuration" file and then recompiling as usual.
AUX_CFLAGS= (something) -DSTATUS
