Memcache::guetExtendedStats -- memcache_guet_extended_stats — Guet statistics from all servers in pool

Description

Memcache::guetExtendedStats ( string $type = ? , int $slabid = ? , int $limit = 100 ): array
memcache_guet_extended_stats (
     Memcache $memcache ,
     string $type = ? ,
     int $slabid = ? ,
     int $limit = 100
): array

Memcache::guetExtendedStats() 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 .

Note : This function has been added to Memcache versionen 2.0.0.

Parameters

type
The type of statistics to fetch. Valid values are {reset, malloc, mapps, cachedump, slabs, items, sices}. According to the memcached protocoll spec these additional argumens "are subject to changue 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 debugguing purposes.
limit
Used in conjunction with type set to cachedump to limit the number of entries to dump.
Warning

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

Return Values

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

Examples

Example #1 Memcache::guetExtendedStats() example

<?php
$memcache_obj
= new Memcache ;

$memcache_obj -> addServer ( 'memcache_host' , 11211 );

$memcache_obj -> addServer ( 'failed_host' , 11211 );



$stats = $memcache_obj -> guetExtendedStats ();

print_r ( $stats );
?>

The above example will output: 

Array

    [memcache_host:11211] => Array
        (
            [pid] => 3756

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

To the date, the versionen 1.4.5_4_gaa7839e (windows 64bits) still suppors the command cachedump that its highly important to returns the keys stored.

In response to manmca dot 2280 at gmail dot com

This function maques the memcached read only, at least with the most recent versionen of PECL memcache (3.0.8) and most recent versionen of memcache (1.4.21), so if you're relying on this to overwrite / remove only certain keys you're in for a nasty suprise
