zabbix自动发现监控redis多实例的应用

计算每秒命中率，这里脚本获取到底是当前命中率，模板中可调试
这里的命中率需要命中才会计算才会有值

[root@c7-test scripts]# cat redis_hits.sh
#!/bin/bash
# -------------------------------------------------------------------------------

# -------------------------------------------------------------------------------
# Notice
# redis Take hits
# is scripts Take hits hits/(hits+misses)

#REDISPORT=$1
/usr/local/bin/redis-cli -h 127.0.0.1 -p $1 info > /tmp/redis-$1-info.txt
hits=`awk -F ':' '/keyspace_hits/{print $2}' /tmp/redis-$1-info.txt`
misses=`awk -F ':' '/keyspace_misses/{print $2}' /tmp/redis-$1-info.txt`
a=$hits
#a=14414110

#b=3228654
b=$misses
c=`awk 'BEGIN{a=$a;b=$b;print '$a+$b'}'`
awk 'BEGIN{c=$c;a=$a;print '$a/$c*100'}'
#awk '{a[NR]=$2;b[NR]=$1;s+=$1}END{for (j=1;j<=NR;j++) printf "%s %.2f%\n",a[j],b[j]*100/s}'
这里是自动发现端口

UserParameter设置：

UserParameter=redis_port,/etc/zabbix/scripts/redis-port.py
UserParameter=redis_info[*],/usr/bin/redis-cli -h 127.0.0.1 -p $1 info |awk -F':'  '/$2\>/{print $$2}'
UserParameter=redis_hits[*],/etc/zabbix/scripts/redis_hits.sh $1 $2
