zabbix示例之监控Redis状态（九）
监控redis也是通过info信息来监控redis的状态：http://www.51niux.com/?id=130 #此链接里面有info信息各参数的意思
一、 zabbix监控单实例redis（通过自动发现的方式）
#这种方式呢也是不太推荐的一种方式，虽然比较省事，但是在出图上面就有点麻烦了，这里脚本格式就不写的那么严谨了。
1.1 客户端的配置
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:$0 redis_parameter_discovery"
;;
esac#这是是根据之前写的硬盘自动发现。网卡自动发现的脚本改的，这种就是将redis的info信息里面左边的参数名都提取出来输出为json格式。
创建上面脚本对应的目录和文件：
#mkdir /home/zabbix/tmp
#touch /home/zabbix/tmp/info.txt
#touch /home/zabbix/tmp/info_parameter
#chown -R zabbix:zabbix /home/zabbix
#chmod 777 /home/zabbix/tmp/{info.txt,info_parameter}
编写redis的info取值的脚本：
# cat /etc/zabbix/scripts/redis_info.sh #这个脚本就是根据自动发现传过来的info的参数名进行grep取值
#!/bin/bash
/usr/local/bin/redis-cli -p 3000 -a redis66cs "info">/home/zabbix/tmp/info.txt
Redis_Site=`cat /home/zabbix/tmp/info_parameter`
Redis_info_value=$(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 #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

1.2 zabbix_proxy代理的操作
#/usr/local/zabbix/bin/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
