1.创建redis监控脚本

1.1 创建脚本

在/etc/zabbix/zabbix_agentd.d/下新建文件redis_status.sh,内容如下：

#!/bin/bash
REDISCLI="/usr/bin/redis-cli"
HOST="127.0.0.1"
PORT=6379
PASS=""

if [[ $# == 1 ]];then
    case $1 in
        version)
            result=`$REDISCLI -h $HOST  -p $PORT info server | grep -w "redis_version" | awk -F':' '{print $2}'`
            echo $result
        ;;
        uptime)
            result=`$REDISCLI -h $HOST  -p $PORT info server | grep -w "uptime_in_seconds" | awk -F':' '{print $2}'`
            echo $result
        ;;
        connected_clients)
            result=`$REDISCLI -h $HOST  -p $PORT info clients | grep -w "connected_clients" | awk -F':' '{print $2}'`
            echo $result
        ;;
        blocked_clients)
            result=`$REDISCLI -h $HOST  -p $PORT info clients | grep -w "blocked_clients" | awk -F':' '{print $2}'`
            echo $result
        ;;
        used_memory)
            result=`$REDISCLI -h $HOST  -p $PORT info memory | grep -w "used_memory" | awk -F':' '{print $2}'`
            echo $result
        ;;
        used_memory_rss)
            result=`$REDISCLI -h $HOST  -p $PORT info memory | grep -w "used_memory_rss" | awk -F':' '{print $2}'`
            echo $result
        ;;
        used_memory_peak)
            result=`$REDISCLI -h $HOST  -p $PORT info memory | grep -w "used_memory_peak" | awk -F':' '{print $2}'`
            echo $result
        ;;
        used_memory_lua)
            result=`$REDISCLI -h $HOST  -p $PORT info memory | grep -w "used_memory_lua" | awk -F':' '{print $2}'`
            echo $result
        ;;
        used_cpu_sys)
            result=`$REDISCLI -h $HOST  -p $PORT info cpu | grep -w "used_cpu_sys" | awk -F':' '{print $2}'`
            echo $result
        ;;
        used_cpu_user)
            result=`$REDISCLI -h $HOST  -p $PORT info cpu | grep -w "used_cpu_user" | awk -F':' '{print $2}'`
            echo $result
        ;;
        used_cpu_sys_children)
            result=`$REDISCLI -h $HOST  -p $PORT info cpu | grep -w "used_cpu_sys_children" | awk -F':' '{print $2}'`
            echo $result
        ;;
        used_cpu_user_children)
            result=`$REDISCLI -h $HOST  -p $PORT info cpu | grep -w "used_cpu_user_children" | awk -F':' '{print $2}'`
            echo $result
        ;;
        rdb_last_bgsave_status)
            result=`$REDISCLI -h $HOST  -p $PORT info Persistence | grep -w "rdb_last_bgsave_status" | awk -F':' '{print $2}' | grep -c ok`
            echo $result
        ;;
        aof_last_bgrewrite_status)
            result=`$REDISCLI -h $HOST  -p $PORT info Persistence | grep -w "aof_last_bgrewrite_status" | awk -F':' '{print $2}' | grep -c ok`
            echo $result
        ;;
        aof_last_write_status)
            result=`$REDISCLI -h $HOST  -p $PORT info Persistence | grep -w "aof_last_write_status" | awk -F':' '{print $2}' | grep -c ok`
            echo $result
        ;;
        *)
            echo -e "\033[33mUsage: $0 {connected_clients|blocked_clients|used_memory|used_memory_rss|used_memory_peak|used_memory_lua|used_cpu_sys|used_cpu_user|used_cpu_sys_children|used_cpu_user_children|rdb_last_bgsave_status|aof_last_bgrewrite_status|aof_last_write_status}\033[0m"
        ;;
    esac
elif [[ $# == 2 ]];then
    case $2 in
        keys)
            result=`$REDISCLI -h $HOST  -p $PORT info | grep -w "$1" | grep -w "keys" | awk -F'=|,' '{print $2}'`
            echo $result
        ;;
        expires)
            result=`$REDISCLI -h $HOST  -p $PORT info | grep -w "$1" | grep -w "keys" | awk -F'=|,' '{print $4}'`
            echo $result
        ;;
        avg_ttl)
            result=`$REDISCLI -h $HOST  -p $PORT info | grep -w "$1" | grep -w "avg_ttl" | awk -F'=|,' '{print $6}'`
            echo $result
        ;;
        *)
            echo -e "\033[33mUsage: $0 {db0 keys|db0 expires|db0 avg_ttl}\033[0m" 
        ;;
    esac
fi

注意：若redis有密码，则需要在$HOST后加上-a $PASS参数。

1.2 赋予脚本可执行权限

chmod +x /etc/zabbix/zabbix_agentd.d/redis_status.sh

1.3 脚本测试

[root@test-server zabbix_agentd.d]# bash redis_status.sh version
3.2.12

2.创建redis监控配置文件

2.1 创建文件

在 /etc/zabbix/zabbix_agentd.d下新建redis.conf文件，内容如下：

UserParameter=Redis.Status,status=`/usr/local/bin/redis-cli -h 127.0.0.1 -p 6379 ping|grep -c PONG` &&echo $status
UserParameter=Redis.Info[*],/etc/zabbix/zabbix_agentd.d/redis_status.sh $1 $2

2.2 重启zabbix-agent:

systemctl restart zabbix-agent

3.创建并导入监控模板

3.1 创建监控模板

redis-template.xml文件内容参考github：

3.2 导入监控模板（不用zabbix自带的redis模板）

配置-模板-导入

点击选择文件，找到redis-template.xml文件，将其导入

4.给主机添加监控模板

监控效果如图：

5.参考

线上zabbix监控redis和redis集群
