/* 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.]
