PHP5 中的 memcache pecl中，含有 memcache.php 可以監控、查詢 memcached 的狀態
界面風格類似於 apc內建的 apc.php
除了詳細的統計資訊外
也可以刪除特定的資料、flush memcached 的所有資料

memcache.php 要修改的設定資料：
define('ADMIN_USERNAME','nike'); // Admin Username
define('ADMIN_PASSWORD','pwpwpw'); // Admin Password
define('DATE_FORMAT','Y/m/d H:i:s');
define('GRAPH_SIZE',200);
define('MAX_ITEM_DUMP',50);
//若有多組 memcached 要監控，可以一行行加上
$MEMCACHE_SERVERS[] = '192.168.0.13:11211'; // add more as an array
$MEMCACHE_SERVERS[] = '192.168.0.22:1121'; // add more as an array

另外
還有個 memcached Cacti Template 的 cacti template
可以記錄類似 MRTG 的圖形
