// server_status.php
// (or server_status.php?xml=1)
//
// outputs general information about BOINC server status gathered from
// config.xml or mysql database queries. If you are running all your
// services on one machine, and the database isn't so large, this should
// work right out of the box. Otherwise see configureables below.
//
// Daemons in config.xml are checked to see if they are running by ssh'ing
// into the respective hosts and searching for active pids. Passwordless
// logins must be in effect if there are multiple hosts involved.
//
// The database queries may be very slow. You might consider running these
// queries elsewhere via cronjob, outputing numbers into a readable file,
// and then getting the latest values with a `/bin/tail -1 data_file`.
// See commented example in the code.
//
// You can get an xml version of the stats via the web when the url has the
// optional "?xml=1" tag at the end, i.e
// http://yourboincproject.edu/server_status.php?xml=1
//
// You should edit the following variables in config.xml to suit your needs:
//
// <www_host> hostname of web server (default: same as <host>)
// <sched_host> hostname of scheduling server (default: same as <host>)
// <uldl_host> hostname of upload/download server (default: same as <host>)
// <uldl_pid> pid file of upload/download server httpd.conf
// (default: /etc/httpd/run/httpd.pid)
// <ssh_exe> path to ssh (default: /usr/bin/ssh)
// <ps_exe> path to ps (which supports "w" flag) (default: /bin/ps)
