Memcache::getExtendedStats — Get statistics from all servers in pool

Описание

array Memcache::getExtendedStats ([ string $type [, int $slabid [, int $limit = 100 ]]] )

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.

Замечание:

This function has been added to Memcache version 2.0.0.

Список параметров

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 type set 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 type set to cachedump to limit the number of entries to dump.

Внимание

The cachedump stat type has been removed from the memcached daemon due to security reasons.

Возвращаемые значения

Returns a two-dimensional associative array of server statistics or FALSE on failure.
