Zabbix监控memcache示例
一、创建memcached-tool脚本参见http://www.linuxidc.com/Linux/2014-08/105157.htm
mkdir /scripts && cd /scripts && vim memcache-tool.pl将脚本copy进入memcache-tool.pl
chmod +x /scripts/memcache-tool.pl
二、用脚本查看memcache的各类统计数据
/scripts/memcache-tool.pl 127.0.0.1:11211 stats
#127.0.0.1:11211 Field Value
accepting_conns 1

total_connections 18
total_items 0
touch_hits 0
touch_misses 0
uptime 2574
version 1.4.15 三、在zabbix_agent.conf中自定义UserParameter
修改以下的参数：
UnsafeUserParameters=1
UserParameter=MemcacheStats
[*],/scripts/memcache-tool.pl 127.0.0.1:11211 stats|grep $1 |awk '{print $NF}' 然后重启zabbix_agent进程
四、在zabbix中添加item
例如，添加当前“curr_connections”
http://s3.运维网.com/wyfs02/M00/5B/76/wKioL1UJxG2y5QoLAADMQH1Z48A053.jpg
保存即可。
*如果出现“Not supported by Zabbix Agent”的错误，
通过下面的命令得到详细的信息：
zabbix_agent -t MemcacheStats] 或者修改zabbix_server.conf中的
Timeout=3#将这个值调整的大一点
