Memcache::getExtendedStats

Get statistics from all servers in pool ()
array Memcache::getExtendedStats ( [string type [, int slabid [, int limit]]] )

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.

Note:

This function has been added to Memcache version 2.0.0.

Parameters

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. Default value is 100.

Return Values

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