WARNING! sizes is a development command.

As of 1.4 it is still the only command which will lock your memcached instance for some time.

If you have many millions of stored items, it can become unresponsive for several minutes.

Run this at your own risk. It is roadmapped to either make this feature optional

or at least speed it up.

2：给脚本添加执行权限
chmod +x memcached.sh
chmod +x memcached-tool.pl
3：zabbix agentd端添加配置文件

vim /etc/zabbix/zabbix_agentd.conf

UserParameter=memcached_stats[*],/etc/zabbix/memcached.sh $1
4：重启服务
/etc/init.d/zabbix-agent restart
5：本地获取数据测试
/etc/zabbix/memcached-tool.pl 127.0.0.1:11211 stats| awk '!(NR==1)' | grep -w "accepting_conns"  | awk '{print $NF}'
zabbix_agentd_memcached.
6: server端获取数据
 /usr/local/zabbix/bin/zabbix_get -s192.168.1.101 -p10050 -k memcached_stats[uptime]
zabbix_server_memcached

web端配置
