监控memcached

监控memcached的运行情况还是很有必要的，当前尝试了如下几种方式：

1。telnet方式

通过运行命令行telnet 127.0.0.1 11211，然后运行stats，得到如下内容：

stats

STATpid2220

STATuptime272669

STATtime1249292478

STATversion1.2.1

STATpointer_size32

STATcurr_items4

STATtotal_items4

STATbytes986

STATcurr_connections21

STATtotal_connections51

STATconnection_structures27

STATcmd_get13

STATcmd_set4

STATget_hits9

STATget_misses4

STATbytes_read1152

STATbytes_written2112

STATlimit_maxbytes67108864

2。MemCacheD Manager, by Nick Pirocanac

安装完毕后，add server，输入ip即可，显示界面如下：

Or,just do a simple connect to the port where memcached is listening. Youcan run a simple command like 'version' or 'stats' to see if memcachedis listening.
