Zabbix监控Redis状态

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 '{ '
printf ' "data":[ '
for((i=0;i<${Redis_Site_Num};i++))
{
if [ `expr $i + 1 ` != ${Redis_Site_Num} ];then
printf " {"{#SITENAME}":"${Redis_Site_parameter[$i]}"}, "
else
printf " {"{#SITENAME}":"${Redis_Site_parameter[$i]}"} "
fi
}
printf ' ] '
printf '} '
}
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。
