. // 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: // // hostname of web server (default: same as ) // hostname of scheduling server (default: same as ) // hostname of upload/download server (default: same as ) // pid file of upload/download server httpd.conf // (default: /etc/httpd/run/httpd.pid) // path to ssh (default: /usr/bin/ssh) // path to ps (which supports "w" flag) (default: /bin/ps) /////////////////////////////////////////////////////////////////////////////// require_once("../inc/util.inc"); require_once("../inc/xml.inc"); require_once("../inc/cache.inc"); require_once("../inc/translation.inc"); check_get_args(array("xml")); $xml = get_int("xml", true); // daemon status outputs: 1 (running) 0 (not running) or -1 (disabled) // function daemon_status($host, $pidname, $progname, $disabled) { global $ssh_exe, $ps_exe, $project_host; $path = "../../pid_$host/$pidname"; $running = 0; if (is_file($path)) { $pid = file_get_contents($path); if ($pid) { $pid = trim($pid); $command = "$ps_exe ww $pid"; if ($host != $project_host) { $command = "$ssh_exe $host " . $command; } $foo = exec($command); if ($foo) { if (strstr($foo, (string)$pid)) $running = 1; } } } if ($disabled == 1) $running = -1; return $running; } function show_status($host, $progname, $running) { global $xml; $xmlstring = " \n $host\n $progname\n"; $htmlstring = "$progname$host"; if ($running == 1) { $xmlstring .= " running\n"; $htmlstring .= "".tra("Running")."\n"; } elseif ($running == 0) { $xmlstring .= " not running\n"; $htmlstring .= "".tra("Not Running")."\n"; } else { $xmlstring .= " disabled\n"; $htmlstring .= "".tra("Disabled")."\n"; } $xmlstring .= " \n"; $htmlstring .= "\n"; if ($xml) { echo $xmlstring; } else { echo $htmlstring; } return 0; } function show_daemon_status($host, $pidname, $progname, $disabled) { $running = daemon_status($host, $pidname, $progname, $disabled); show_status($host, $progname, $running); } function show_counts($key, $xmlkey, $value) { global $xml; $formattedvalue = number_format($value); $xmlstring = " <$xmlkey>$value\n"; if ($xml) { echo $xmlstring; } else { echo "$key$formattedvalue"; } return 0; } function get_mysql_count($query) { $count = unserialize(get_cached_data(3600, "get_mysql_count".$query)); if ($count == false) { $result = mysql_query("select count(*) as count from " . $query); $count = mysql_fetch_object($result); mysql_free_result($result); $count = $count->count; set_cached_data(3600, serialize($count), "get_mysql_count".$query); } return $count; } function get_mysql_value($query) { $value = unserialize(get_cached_data(3600, "get_mysql_value".$query)); if ($value == false) { $result = mysql_query($query); $row = mysql_fetch_object($result); mysql_free_result($result); $value = $row->value; set_cached_data(3600, serialize($value), "get_mysql_value".$query); } return $value; } function get_mysql_assoc($query) { $assoc = unserialize(get_cached_data(3600, "get_mysql_assoc".$query)); if ($assoc == false) { $sql = "SELECT * FROM app WHERE deprecated != 1"; $result = mysql_query($sql); while($row = mysql_fetch_assoc($result)) { $assoc[] = $row; } mysql_free_result($result); set_cached_data(3600, serialize($assoc), "get_mysql_assoc".$query); } return $assoc; } function get_mysql_user($clause) { $count = unserialize(get_cached_data(3600, "get_mysql_user".$clause)); if ($count == false) { $result = mysql_query("select count(userid) as userid from (SELECT distinct userid FROM result where validate_state=1 and received_time > (unix_timestamp()-(3600*24*1)) " . $clause .
