1、python支持
yum -y install python-simplejson

2、discovery脚本
[root@localhost etc]# cat  redis_port.py

#!/usr/bin/env python 
import os 
#import json 
import simplejson as json  #特别要注意的地方 
t=os.popen("""sudo netstat -tlpn |grep redis-server|grep 0.0.0.0|awk '{print $4}'|awk -F: '{print $2}' """) 
ports = [] 
for port in  t.readlines(): 
        r = os.path.basename(port.strip()) 
        ports += [{'{#REDISPORT}':r}] 
print json.dumps({'data':ports},sort_keys=True,indent=4,separators=(',',':'))

3,、试执行脚本
[root@localhost etc]# python redis_port.py
{
    "data":[
        {
            "{#REDISPORT}":"6379"
        }
    ]
}

4,zabbix_agent设置
[root@localhost ~]# tail -n 2 /usr/local/zabbix/etc/zabbix_agentd.conf
UserParameter=redis.discovery,/usr/local/zabbix/etc/redis_port.py
UserParameter=redis_stats[*],redis-cli -h 127.0.0.1 -a redis_passwd -p $1 info|grep $2|cut -d : -f2
[root@localhost ~]# chmod a+x /usr/local/zabbix/etc/redis_port.py

5,sudo权限
[root@localhost ~]# tail -n 1 /etc/sudoers
zabbix ALL=(root) NOPASSWD:/bin/netstat
[root@localhost ~]# sed -i 's/^Defaults.*.requiretty/#Defaults    requiretty/' /etc/sudoers
[root@localhost ~]# grep requiretty /etc/sudoers
#Defaults    requiretty
# changed in order to be able to use sudo without a tty. See requiretty above.

6,服务端验证
[root@zabbixserver-nginx ~]# zabbix_get -s 172.17.2.114 -k redis.discovery
{
    "data":[
        {
            "{#REDISPORT}":"6379"
        }
    ]
}

[root@zabbixserver-nginx ~]# zabbix_get -s 172.17.2.114 -k redis_stats[6379,used_memory:]
651534360
[root@zabbixserver-nginx ~]# zabbix_get -s 172.17.2.114 -k "redis_stats[6379,blocked_clients]"
0

7,zabbix web界面导入下载的模板,添加监控项后检查监控图像
