/* Status Module. Display lots of internal data about how Apache is

|
* performing and the state of all children processes.
|
|
*
|
|
* To enable this, add the following lines into any config file:
|
|
*
|
|
* <Location /server-status>
|
|
* SetHandler server-status
|
|
* </Location>
|
|
*
|
|
* You may want to protect this location by password or domain so no one

|
* else can look at it. Then you can access the statistics with a URL like:
|
|
*
|
|
* http://your_server_name/server-status
|
|
*
|
|
* /server-status - Returns page using tables
|
|
* /server-status?notable - Returns page for browsers without table support
|
|
* /server-status?refresh - Returns page with 1 second refresh
|
|
* /server-status?refresh=6 - Returns page with refresh every 6 seconds
|
|
* /server-status?auto - Returns page with data for automatic parsing
|

|
|

|
|
* 13.3.96 Updated to remove rprintf's [Mark]
|
|
* 18.3.96 Added CPU usage, process information, and tidied [Ben Laurie]
|
|
* 18.3.96 Make extra Scoreboard variables #definable
|
|
* 25.3.96 Make short report have full precision [Ben Laurie suggested]
|
|
* 25.3.96 Show uptime better [Mark/Ben Laurie]
|
|
* 29.3.96 Better HTML and explanation [Mark/Rob Hartill suggested]
|
|
* 09.4.96 Added message for non-STATUS compiled version
|
|
* 18.4.96 Added per child and per slot counters [Jim Jagielski]
|
|
* 01.5.96 Table format, cleanup, even more spiffy data [Chuck Murcko/Jim J.]
|
|
* 18.5.96 Adapted to use new rprintf() routine, incidentally fixing a missing
|
|
* piece in short reports [Ben Laurie]
|
|
* 21.5.96 Additional Status codes (DNS and LOGGING only enabled if
|
|
* extended STATUS is enabled) [George Burgyan/Jim J.]
|
|
