# 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";
