配置 Zabbix 监控 Redis .

实验平台：CentOS 7.6.1810

zabbix-Server 版本：5.0.2

zabbix-agent 版本：5.0.2

MySQL 版本：5.7

1.redis 安装这里省略

可以参看 Redis安装及集群安装

2.编写 redis 获取数据脚本

主要通过 redis info 来获取数据

$ vim /usr/local/zabbix-agent/bash/redismonitor.sh
#! /bin/bash
#Name: redismontior.sh
REDISCLI="/usr/bin/redis-cli" 
HOST="127.0.0.1"
PORT=6379

if [[ $# == 1 ]];then
    case $1 in
        version)
            result=`$REDISCLI -h $HOST -p $PORT info | grep -w "redis_version" | awk -F':' '{print $2}'`
            echo $result
        ;;
        uptime)
            result=`$REDISCLI -h $HOST -p $PORT info | grep -w "uptime_in_seconds" | awk -F':' '{print $2}'`
            echo $result
        ;;
        connected_clients)
            result=`$REDISCLI -h $HOST -p $PORT info | grep -w "connected_clients" | awk -F':' '{print $2}'`
            echo $result
        ;;
        blocked_clients)
            result=`$REDISCLI -h $HOST -p $PORT info | grep -w "blocked_clients" | awk -F':' '{print $2}'`
            echo $result
        ;;
        used_memory)
            result=`$REDISCLI -h $HOST -p $PORT info | grep -w "used_memory" | awk -F':' '{print $2/1024/1024}' | cut -f1 -d"."`
            echo $result
        ;;
        used_memory_rss)
            result=`$REDISCLI -h $HOST -p $PORT info | grep -w "used_memory_rss" | awk -F':' '{print $2}'`
            echo $result
        ;;
        used_memory_peak)
            result=`$REDISCLI -h $HOST -p $PORT info | grep -w "used_memory_peak" | awk -F':' '{print $2}'`
            echo $result
        ;;
        used_memory_lua)
            result=`$REDISCLI -h $HOST -p $PORT info | grep -w "used_memory_lua" | awk -F':' '{print $2}'`
            echo $result
        ;;
        used_cpu_sys)
            result=`$REDISCLI -h $HOST -p $PORT info | grep -w "used_cpu_sys" | awk -F':' '{print $2}'`
            echo $result
        ;;
        used_cpu_user)
            result=`$REDISCLI -h $HOST -p $PORT info | grep -w "used_cpu_user" | awk -F':' '{print $2}'`
            echo $result
        ;;
        used_cpu_sys_children)
            result=`$REDISCLI -h $HOST -p $PORT info | grep -w "used_cpu_sys_children" | awk -F':' '{print $2}'`
            echo $result
        ;;
        used_cpu_user_children)
            result=`$REDISCLI -h $HOST -p $PORT info | grep -w "used_cpu_user_children" | awk -F':' '{print $2}'`
            echo $result
        ;;
        rdb_last_bgsave_status)
            result=`$REDISCLI -h $HOST -p $PORT info  | 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  | 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  | 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

3.验证脚本可用性

$ /usr/local/zabbix-agent/bash/redismonitor.sh version
6.0.8

4.编辑 zabbix 配置文件

$ vim /usr/local/zabbix-agent/etc/zabbix_agentd.conf
UnsafeUserParameters=1
UserParameter=redis.status[*],/usr/local/zabbix-agent/bash/redismonitor.sh $1

5.重启 agent
