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
821512
创建redis模板
1.创建模板
2.创建应用集
3.添加自动发现规则
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。
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
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.
