Memcache::getExtendedStats
(PECL memcache >= 2.0.0)
Memcache::getExtendedStats — Get statistics from all servers in pool
Beschreibung
$type = ?, int $slabid = ?, int $limit = 100): array
Memcache::getExtendedStats() returns a two-dimensional
associative array with server statistics. Array keys correspond to
host:port of server and values contain the individual server statistics.
A failed server will have its corresponding entry set to false.
You can also use the memcache_get_extended_stats() function.
Hinweis:
This function has been added to Memcache version 2.0.0.
Parameter-Liste
-
type -
The type of statistics to fetch. Valid values are {reset, malloc, maps, cachedump, slabs, items, sizes}. According to the memcached protocol spec these additional arguments "are subject to change for the convenience of memcache developers".
-
slabid -
Used in conjunction with
typeset to cachedump to identify the slab to dump from. The cachedump command ties up the server and is strictly to be used for debugging purposes. -
limit -
Used in conjunction with
typeset to cachedump to limit the number of entries to dump.
The cachedump stat type has been removed from the memcached daemon due to security reasons.
Rückgabewerte
Returns a two-dimensional associative array of server statistics or false
on failure.
Beispiele
Beispiel #1 Memcache::getExtendedStats() example
<?php
$memcache_obj = new Memcache;
$memcache_obj->addServer('memcache_host', 11211);
$memcache_obj->addServer('failed_host', 11211);
$stats = $memcache_obj->getExtendedStats();
print_r($stats);
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
