// server_status.php [-f xml_output_filename]
|
|
// (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
|
|
//
|
|
// If running as a standalone program there is an optional -f flag where
|
|
// you can generate xml server status output to the filename you provide
|
|
// (this will output both html to stdout and xml to the filename given).
|
|
// Some may prefer to do this if takes so long to dredge up the stats for
|
|
// the html, you won't have to do it again to generate the xml.
|
|
//
|
|
// It is highly recommended that you run this program every 10 minutes and
|
|
// send its stdout to an .html file, rather than having the values get
|
|
// regenerated every time the page is accessed. Or use the available
|
|
// web page cache utilities.
|
|
//
|
|
// 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)
