Memcached::getStats — 获取服务器池的统计信息
Memcached::getStats() 返回一个包含所有可用memcache服务器状态的数组. 返回的统计信息的详细描述参见» memcache protocol。 (译注:经实验,服务器池中有不可用服务器时,返回false)
此函数没有参数。
服务器统计信息数组, 每个服务器一项。
Example #1 Memcached::getStats() 示例
<?php
$m = new Memcached ();
$m -> addServer ( 'localhost' , 11211 );
print_r ( $m -> getStats ());
?>
以上例程的输出类似于:
Array ( [localhost:11211] => Array ( [pid] => 4933 [uptime] => 786123 [threads] => 1 [time] => 1233868010 [pointer_size] => 32 [rusage_user_seconds] => 0 [rusage_user_microseconds] => 140000 [rusage_system_seconds] => 23 [rusage_system_microseconds] => 210000 [curr_items] => 145 [total_items] => 2374 [limit_maxbytes] => 67108864 [curr_connections] => 2 [total_connections] => 151 [connection_structures] => 3 [bytes] => 20345 [cmd_get] => 213343 [cmd_set] => 2381 [get_hits] => 204223 [get_misses] => 9120 [evictions] => 0 [bytes_read] => 9092476 [bytes_written] => 15420512 [version] => 1.2.6 ))

The method currently does not support the optional (and subject to change) type parameter for the stats command:
- "items", "sizes", "slabs"
The documentation for the optional parameters can be found here (sections below General-purpose statistics):
http://code.sixapart.com/svn/memcached/trunk/server/doc/protocol.txt
The Memcache Extension can be uses to retrieve that information:
