/* 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
*
* Mark Cox, mark@ukweb.com, November 1995
*
* 12.11.95 Initial version for www.telescope.org
* 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.]
* 10.8.98 Allow for extended status info at runtime (no more STATUS)
* [Jim J.]
