memcached 

apt-getinstall memcached
systemctl start memcached#端口11211

apt-get install nmap
测试
echo -e "stats\\nquit" | nc 127.0.0.1 11211
root@ubuntu:~# echo -e "stats\\nquit" | nc 127.0.0.1 11211 | grep "total_connections" | awk print $3

监控脚本
root@ubuntu:/etc/zabbix/zabbix_agentd.d# ls
memcached.confmemcached.sh

vim/etc/zabbix/zabbix_agentd.d/memcached.conf
-------------------------------------------------------------------------------------
UserParameter=memcached_status[*],/bin/bash /etc/zabbix/zabbix_agentd.d/memcached.sh $1 $2 $3
-------------------------------------------------------------------------------------
memcached.sh 这个脚本是加了执行权限的,但是为啥前面要加上/bin/bash,zabbix_get才能获取到值？？

#脚本
--------------------------------------------------------------------------
#!/bin/bash
memcached_status()
M_PORT=$1
M_COMMAND=$2
echo -e "stats\\nquit" | nc 127.0.0.1 "$M_PORT" | grep "STAT $M_COMMAND " | awk print $3

main()
case $1 in
memcached_status)
memcached_status $2 $3
; ;
esac

main $1 $2 $3
--------------------------------------------------------------------------
chmod a+x memcached.sh
#测试脚本
root@ubuntu:/etc/zabbix/zabbix_agentd.d# bash memcached.sh memcached_status 11211 total_connections


#在主配置文件打开，默认是打开的
vim /etc/zabbix/zabbix_agentd.conf
------------------------------------------------------
Include=/etc/zabbix/zabbix_agentd.d/*.conf
------------------------------------------------------


在[192.168.47.104测试]
/apps/zabbix_agent/bin/zabbix_get -s 192.168.47.105 -p 10050 -k "memcached_status[memcached_status,11211,total_connections]"
