> 监控redis通过info信息来监控redis的状态

自动发现脚本编写  
cat /etc/zabbix/scripts/redis\_parameter \#自动发现redis脚本参数的脚本

#!/bin/bash
    /usr/local/bin/redis-cli -p 3000 -a  redis66cs "info">/home/zabbix/tmp/info.txt
    cat /tmp/info.txt |grep -v "^#"|awk -F ":" { 'print $1'}|grep -v [[:space:]] >/home/zabbix/tmp/info_parameter
    Redis_parameter_discovery () { 
       Redis_Site=`cat /home/zabbix/tmp/info_parameter`
       Redis_Site_Num=`echo ${ Redis_Site}|awk { 'print NF'}`
       Redis_Site_parameter=($Redis_Site)
       printf '{\n'
       printf '\t"data":[\n'
       for((i=0;i<${ Redis_Site_Num};i++))
       { 
          if [ `expr $i + 1 ` != ${ Redis_Site_Num} ];then  
             printf "\t{\"{#SITENAME}\":\"${Redis_Site_parameter[$i]}\"},\n"
          else
             printf "\t{\"{#SITENAME}\":\"${Redis_Site_parameter[$i]}\"}\n"
          fi
       }
       printf '\t]\n'
       printf '}\n'
    }
    case "$1" in
    redis_parameter_discovery)
       Redis_parameter_discovery
    ;;
    *)
    echo "Usage:$0 redis_parameter_discovery"
    ;;
    esac

创建上面脚本对应的目录和文件：

#mkdir /home/zabbix/tmp
    #touch /home/zabbix/tmp/info.txt
    #touch /home/zabbix/tmp/info_parameter
    #chown -R zabbix:zabbix /home/zabbix
    #chmod 777 /home/zabbix/tmp/{ info.txt,info_parameter}

编写redis的info取值的脚本  
cat /etc/zabbix/scripts/redis\_info.sh \#这个脚本就是根据自动发现传过来的info的参数名进行grep取值

#!/bin/bash
    /usr/local/bin/redis-cli -p 3000 -a  redis66cs "info">/home/zabbix/tmp/info.txt
    Redis_Site=`cat /home/zabbix/tmp/info_parameter`
    Redis_info_value=$(grep "$1"\: /home/zabbix/tmp/info.txt|awk -F ":" { 'print $NF'})
    echo $Redis_info_value

注意这里一定grep 一定要是"$1":这种以:结尾，比如：used\_memory：和 used\_memory\_human:，会精确匹配而非模糊匹配  
编写自定义的key：  
cat /etc/zabbix/zabbix\_agentd.conf.d/redis\_parameter\_discovery.conf  
脚本中的redis.parameter.discovery就是我们自定义的key

UserParameter=redis.parameter.discovery,/etc/zabbix/scripts/redis_parameter redis_parameter_discovery

redis.parameter.discovery这个key的作用就是调用redis\_parameter这个脚本，将redis的所有info的参数名提取出来。  
cat /etc/zabbix/zabbix\_agentd.conf.d/redis\_info\_value.conf  
通过上面自动发现提取出来的参数名作为$1传递给下面的脚本

UserParameter=redis.info.value[*],/etc/zabbix/scripts/redis_info.sh $1

给对应的脚本授权

#chown -R zabbix:zabbix /etc/zabbix/* #chmod +x zabbix:zabbix /etc/zabbix/scripts/*

重启客户端服务

#/etc/init.d/zabbix/zabbix_agentd restart

zabbix\_proxy代理的操作

zabbix_get -s 192.168.14.56 -k redis.parameter.discovery  #测试redis的自动发现info参数的脚本

redis的Info信息总共有82个参数,用上面的自定义key已经都取出来了。

/usr/local/zabbix/bin/zabbix_get -s 192.168.14.56 -k redis.info.value[used_memory]  #测试redis.info.value传参也可以

创建redis模板  
1.创建模板  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwOTA3OTc3_size_16_color_FFFFFF_t_70]  
2.创建应用集  
![在这里插入图片描述][20210116194942471.png]  
3.添加自动发现规则  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwOTA3OTc3_size_16_color_FFFFFF_t_70 1]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwOTA3OTc3_size_16_color_FFFFFF_t_70 2]  
选择主机添加模板  
上面已经将一个简单的Redis模板创建完成了，现在找一个主机进行添加吧。  
![在这里插入图片描述][20210116195013680.png]  
点击此主机的自动发现，如果最后边的状态有红色的叹号，说明哪里会有问题，鼠标移动到叹号哪里也会有提示  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwOTA3OTc3_size_16_color_FFFFFF_t_70 3]  
点击此主机的监控项选择Redis应用集，可以看到我们设置的自动发现规则里面的监控项原型生效了。一共两页82行。  
检查是否有数据  
查看最新数据，选择主机以及应用集，查看是否能采集到数据。

从上图可以看到我们已经可以对redis的info信息的每一项参数进行数据采集了.
