mysql_stat — Zeigt den momentanen Serverstatus an
mysql_stat() liefert den momentanen Serverstatus zurück.
Hinweis:
mysql_stat() liefert nur die Werte uptime, threads, queries, open tables, flush tables und queries pro sec. Für eine komplette Liste der anderen Statusvariablen sollte der SQL-Befehl SHOW STATUS verwendet werden.
Beispiel #1 mysql_stat() Beispiel
<?php
$link = mysql_connect('localhost', "mysql_user", "mysql_password");
$status = explode(' ', mysql_stat($link));
print_r($status);
?>
Das oben gezeigte Beispiel liefert die folgende Ausgabe:
Array
(
[0] => Uptime: 5380
[1] => Threads: 2
[2] => Questions: 1321299
[3] => Slow queries: 0
[4] => Opens: 26
[5] => Flush tables: 1
[6] => Open tables: 17
[7] => Queries per second avg: 245.595
)
Siehe auch mysql_get_server_info() und mysql_list_processes().
The following script can be used to clearly print out the results of mysql_stat().
<?php
mysql_connect("localhost", "username", "password");
$array = explode(" ", mysql_stat());
foreach ($array as $value){
echo $value . "<br />";
}
?>
Outputs something similar to:
Uptime: 698
Threads: 1
Questions: 4
Slow queries: 0
Opens: 19
Flush tables: 1
Open tables: 12
Queries per second avg: 0.5
<?php
$mysql_stat=mysql_stat($dbconnect);
$tot_count=preg_match_all('/([a-z ]+):\s*([0-9.]+)/i', $mysql_stat, $matches);
for ($i=0; $i<$tot_count; $i++) {
$info1=$matches[1][$i];
$info2=$matches[2][$i];
echo "$info1 ($info2)<br>";
}
/*
example output:
Uptime (13651)
Threads (1)
Questions (12910)
Slow queries (0)
Opens (314)
Flush tables (1)
Open tables (24)
Queries per second avg (0.945)
*/
?>
<?php
// function that return stat elements into array
function mysql_stat_array($A=null) {
$status = explode(' ', mysql_stat());
foreach($status as $k=>$v) { $v=explode(':',$v,2); $status[$v[0]]=$v[1]; }
return (isset($status[$A])?$status[$A]:$status);
}
/*
example return:
Array ( [0] => Uptime: 385815 [1] => Threads: 1 [2] => Questions: 3515 [3] => Slow queries: 0 [4] => Opens: 32 [5] => Flush tables: 1 [6] => Open tables: 8 [7] => Queries per second avg: 0.009 [Uptime] => Array ( [0] => Uptime [1] => 385815 ) [Threads] => Array ( [0] => Threads [1] => 1 ) [Questions] => Array ( [0] => Questions [1] => 3515 ) [Slow queries] => Array ( [0] => Slow queries [1] => 0 ) [Opens] => Array ( [0] => Opens [1] => 32 ) [Flush tables] => Array ( [0] => Flush tables [1] => 1 ) [Open tables] => Array ( [0] => Open tables [1] => 8 ) [Queries per second avg] => Array ( [0] => Queries per second avg [1] => 0.009 ) )
*/
?>
if you need the complete status as outputted by the "show status" command. Try this function.
<?
function mysql_status($db=NULL) {
if(!mysql_ping($db))
$db=mysql_connect("localhost","user","password");
$res=mysql_query("show status",$db);
while (list($key,$value)=mysql_fetch_array($res))
$sql[$key]=$value;
return $sql;
}
?>
