Memcache::getStats
(PECL memcache >= 0.2.0)
Memcache::getStats — Obtiene estadísticas del servidor
Descripción
array Memcache::getStats
([ string
$type
[, int $slabid
[, int $limit = 100
]]] )Memcache::getStats() devuelve un array asociativo con las estadísticas del servidor. Las llaves del array corresponden a los parámetros de las estadísticas y los valores a los valores de los parámetros. También se puede usar la función memcache_get_stats().
Parámetros
-
type -
Tipo de estadísticas a capturar. Valores válidos son {reset, malloc, maps, cachedump, slabs, items, sizes}. Según la especificación del protocolo de memcached estos son los argumentos adicionales "pueden estar sujetos a cambios por conveniencia de los desarrolladores de memcache".
-
slabid -
Usado en conjunto con cachedump en el
typepara identificar el slap desde donde volcar. El comando cachedump va en conjunto con el servidor y debe ser usado estrictamente para propósitos de depuración. -
limit -
Usado en conjunto con cachedump en el
typepara limitar el número de entradas a volcar.
Valores devueltos
Devuelve un array asociativo con las estadísticas del servidor o FALSE en caso de error.

Here is a memcache stats analyzer method that can be used to print memcache stats in a nice informative tabular format.
<?php
function printDetails($status){
echo "<table border='1'>";
echo "<tr><td>Memcache Server version:</td><td> ".$status ["version"]."</td></tr>";
echo "<tr><td>Process id of this server process </td><td>".$status ["pid"]."</td></tr>";
echo "<tr><td>Number of seconds this server has been running </td><td>".$status ["uptime"]."</td></tr>";
echo "<tr><td>Accumulated user time for this process </td><td>".$status ["rusage_user"]." seconds</td></tr>";
echo "<tr><td>Accumulated system time for this process </td><td>".$status ["rusage_system"]." seconds</td></tr>";
echo "<tr><td>Total number of items stored by this server ever since it started </td><td>".$status ["total_items"]."</td></tr>";
echo "<tr><td>Number of open connections </td><td>".$status ["curr_connections"]."</td></tr>";
echo "<tr><td>Total number of connections opened since the server started running </td><td>".$status ["total_connections"]."</td></tr>";
echo "<tr><td>Number of connection structures allocated by the server </td><td>".$status ["connection_structures"]."</td></tr>";
echo "<tr><td>Cumulative number of retrieval requests </td><td>".$status ["cmd_get"]."</td></tr>";
echo "<tr><td> Cumulative number of storage requests </td><td>".$status ["cmd_set"]."</td></tr>";
$percCacheHit=((real)$status ["get_hits"]/ (real)$status ["cmd_get"] *100);
$percCacheHit=round($percCacheHit,3);
$percCacheMiss=100-$percCacheHit;
echo "<tr><td>Number of keys that have been requested and found present </td><td>".$status ["get_hits"]." ($percCacheHit%)</td></tr>";
echo "<tr><td>Number of items that have been requested and not found </td><td>".$status ["get_misses"]."($percCacheMiss%)</td></tr>";
$MBRead= (real)$status["bytes_read"]/(1024*1024);
echo "<tr><td>Total number of bytes read by this server from network </td><td>".$MBRead." Mega Bytes</td></tr>";
$MBWrite=(real) $status["bytes_written"]/(1024*1024) ;
echo "<tr><td>Total number of bytes sent by this server to network </td><td>".$MBWrite." Mega Bytes</td></tr>";
$MBSize=(real) $status["limit_maxbytes"]/(1024*1024) ;
echo "<tr><td>Number of bytes this server is allowed to use for storage.</td><td>".$MBSize." Mega Bytes</td></tr>";
echo "<tr><td>Number of valid items removed from cache to free memory for new items.</td><td>".$status ["evictions"]."</td></tr>";
echo "</table>";
}
?>
Sample usage:
<?php
$memcache_obj = new Memcache;
$memcache_obj->addServer('memcache_host', 11211);
printDetails($memcache_obj->getStats());
?>
