一.安装并配置memcached服务
1>.使用yum方式安装memcached
[root@node201.yinzhengjie.org.cn ~]# yum -y install memcached

[root@node201.yinzhengjie.org.cn ~]#
[root@node201.yinzhengjie.org.cn ~]# yum -y install memcached
2>.查看memcached的配置文件
[root@node201.yinzhengjie.org.cn ~]# cat /etc/sysconfig/memcached
PORT=""
USER="memcached"
MAXCONN=""
CACHESIZE=""
OPTIONS=""
[root@node201.yinzhengjie.org.cn ~]#
3>.启动memcached服务
[root@node201.yinzhengjie.org.cn ~]# systemctl start memcached.service
[root@node201.yinzhengjie.org.cn ~]#
[root@node201.yinzhengjie.org.cn ~]# systemctl enable memcached.service
Created symlink from /etc/systemd/system/multi-user.target.wants/memcached.service to /usr/lib/systemd/system/memcached.service.
[root@node201.yinzhengjie.org.cn ~]#
[root@node201.yinzhengjie.org.cn ~]# ss -ntl | grep
LISTEN *: *:*
LISTEN ::: :::*
[root@node201.yinzhengjie.org.cn ~]#
[root@node201.yinzhengjie.org.cn ~]#
二. zabbix agent端配置监控memcached的脚本
1>. 在命令行中查看数据 memcached 的监控指标
[root@node201.yinzhengjie.org.cn ~]# yum -y install nc

[root@node201.yinzhengjie.org.cn ~]#
[root@node201.yinzhengjie.org.cn ~]# yum -y install nc #安装nc工具
[root@node201.yinzhengjie.org.cn ~]# echo -e "stats\nquit" | nc 127.0.0.1 ""

2>.编写脚本获取memcached的监控项数据
[root@node201.yinzhengjie.org.cn ~]# cat /etc/zabbix/zabbix_agentd.d/memcached_monitoring.sh
#!/bin/bash

echo -e "stats\nquit" | nc 127.0.0.1 "$M_PORT" | grep "STAT $M_COMMAND " | awk '{print $3}'
} function main(){

memcached_status)
memcached_status $ $
;;
esac
} main $ $ $
[root@node201.yinzhengjie.org.cn ~]#
[root@node201.yinzhengjie.org.cn ~]# bash /etc/zabbix/zabbix_agentd.d/memcached_monitoring.sh memcached_status curr_connections [root@node201.yinzhengjie.org.cn ~]#
[root@node201.yinzhengjie.org.cn ~]# bash /etc/zabbix/zabbix_agentd.d/memcached_monitoring.sh memcached_status reserved_fds [root@node201.yinzhengjie.org.cn ~]#
3>.给自定义的脚本添加可执行权限
[root@node201.yinzhengjie.org.cn ~]# ll /etc/zabbix/zabbix_agentd.d/memcached_monitoring.sh
-rw-r--r-- root root Feb : /etc/zabbix/zabbix_agentd.d/memcached_monitoring.sh
[root@node201.yinzhengjie.org.cn ~]#
[root@node201.yinzhengjie.org.cn ~]# chmod +x /etc/zabbix/zabbix_agentd.d/memcached_monitoring.sh
[root@node201.yinzhengjie.org.cn ~]#
[root@node201.yinzhengjie.org.cn ~]# ll /etc/zabbix/zabbix_agentd.d/memcached_monitoring.sh
-rwxr-xr-x root root Feb : /etc/zabbix/zabbix_agentd.d/memcached_monitoring.sh
[root@node201.yinzhengjie.org.cn ~]#
[root@node201.yinzhengjie.org.cn ~]#
4>.修改zaibbix agent的配置文件
[root@node201.yinzhengjie.org.cn ~]# grep ^Include /etc/zabbix/zabbix_agentd.conf
Include=/etc/zabbix/zabbix_agentd.d/*.conf
[root@node201.yinzhengjie.org.cn ~]#
[root@node201.yinzhengjie.org.cn ~]# cat /etc/zabbix/zabbix_agentd.d/yinzhengjie_monitoring.conf
UserParameter=tcp_status_monitoring[*],/etc/zabbix/zabbix_agentd.d/tcp_status_monitoring.sh $1 $2
UserParameter=memcached_monitoring[*],/etc/zabbix/zabbix_agentd.d/memcached_monitoring.sh $1 $2 $3
[root@node201.yinzhengjie.org.cn ~]#
5>.重启zabbix agent服务使得配置生效
[root@node201.yinzhengjie.org.cn ~]# systemctl restart zabbix-agent.service
三.zabbix WebUI配置
1>. 在zabbix server测试是否可以获取memcached的监控数据
[root@zabbix203.yinzhengjie.org.cn ~]# /yinzhengjie/softwares/zabbix/bin/zabbix_get -s node201.yinzhengjie.org.cn -p -k "memcached_monitoring[memcached_status 11211 curr_connections]" [root@zabbix203.yinzhengjie.org.cn ~]#
[root@zabbix203.yinzhengjie.org.cn ~]#
[root@zabbix203.yinzhengjie.org.cn ~]# /yinzhengjie/softwares/zabbix/bin/zabbix_get -s node201.yinzhengjie.org.cn -p -k "memcached_monitoring[memcached_status 11211 reserved_fds]" [root@zabbix203.yinzhengjie.org.cn ~]#
2>.自定义memcached的模板
3>.自定义memecached模板监控项图形
4>.自定义触发器
5>.将自定义的memcached模板和对应的zabbix agent主机进行关联
6>.查看图形
