<?php
# server_status.php [-f xml_output_filename]
#
# outputs general information about BOINC server status gathered from
# config.xml or mysql database queries.
#
# 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.
#
# The database queries are rather 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`
#
# 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.
#
# It is highly recommended that you run this program every 10 minutes and
# send its stdout to an .html file every 10 minutes, rather than having
# the values get regenerated every time the page is accessed.
#
# You should edit the following variables below to suit your needs:
# What is the server hosting the WWW site?
$web_host = "WWW host name";
# The machine acting as upload/download server?
$uldl_host = "UL/DL host name";
# Where is the ul/dl apache server pid file?
$uldl_pid = "/apache/var/log/httpd.pid";
# The machine acting as scheduling server?
$sched_host = "Scheduler host name";
# Where is the scheduling apache server pid file?
$sched_pid = "/apache/var/log/httpd.pid";
# Where is ssh?
$ssh_exe = "/usr/local/bin/ssh";
# where is ps (a version that supports the "w" flag)
$ps_exe = "/usr/ucb/ps";
