zabbix web端配置

Configuration-Templates-Import

选择 templates_Redis_info_status_ALL+.xml 并完成导入

找到Redis的host，在Templates里，Link new templates: 输入redis，并选择Template Redis 2，点击：Add-Update

zabbix-agent 端配置

mkdir -p /etc/zabbix/script/redis
cd /etc/zabbix/script/redis

确保在zabbix_agentd.conf里有：

Include=/etc/zabbix/zabbix_agentd.d/*.conf

chmod +x redis.sh
cd /etc/zabbix/zabbix_agent.d
vim zbx_redis.conf

#监控redis状态，我们可以根据这个参数对应的监控项创建redis状态触发器。
UserParameter=redis.status,/usr/local/bin/redis-cli -h 127.0.0.1 -p 6379 -a password ping |grep -c PONG

重启agent

service zabbix-agent restart

测试

在zabbix-server上运行：

/etc/zabbix/script/redis/zbx_redis_stats.py -p 6379 -a redispass L-192.168.0.3 gcc_version none

如果返回值，说明测试正确。
