zabbix监控redis
百度“zabbix监控redis”有说官方有redis的监控脚本和模版，
https://github.com/adubkov/zbx_redis_template
下面为自己手动写脚本添加
将redis监控项都放在一个模版里面
一、监控redis的6379端口
使用自带的监控项：net.tcp.port[127.0.0.1,6379]
二、使用下面这个命令监控redis的状态
root@zabbix:/opt/zabbix# redis-cli -h 127.0.0.1 -p 6379 info

fi五、手动测试，没毛病
root@zabbix:~# systemctl restart zabbix-agent.service
root@zabbix:~# zabbix_get -s 127.0.0.1 -p 10050 -k redis[used_cpu_sys]
4.14
root@zabbix:~# zabbix_get -s 127.0.0.1 -p 10050 -k redis[used_cpu_user]
1.27
root@zabbix:~# zabbix_get -s 127.0.0.1 -p 10050 -k redis[used_memory]
508976六、web界面添加监控项，放到一个模版里面
随便加了几个
触发器：
当redis的6379检测不到就报警
当redis使用内存大于1048576字节（1MB）就报警，
七、关联模版到对应的agent客户端
八、停止redis服务测试
root@zabbix:~# date;systemctl stop redis-server
2018年 12月 24日 星期一 15:45:06 CST报警了：
没问题
内存不足的报警：
九、测试那个所谓的官网模版，用python写的
可以用，很强
127.0.0.1：主机
used_cpu_sys：要监控的东西。可以通过redis info命令出来的哪些选项参数
none：脚本里面写的是db选项的内容，默认为none
