zabbix监控redis命中率---张庆沉笔记

1、编写脚本

redis_info_value.sh

REDISPATH="/usr/bin/redis-cli"
HOST="127.0.0.1"
PORT="6379"
PASSWD="2021"
REDIS_INFO="$REDISPATH -h $HOST -p $PORT -a $PASSWD info"

if [[ $# == 1 ]];then
case $1 inkeyspace_hits)
    result=`$REDIS_INFO 2>/dev/null | grep keyspace_hits|awk -F":" '{print $NF}'`
    echo $result
;;
keyspace_misses)
    result=`$REDIS_INFO 2>/dev/null | grep keyspace_misses|awk -F":" '{print $NF}'`
    echo $result
;;
*)
    echo "argu error"
    ;;
esac
fi

2、zabbix类型选择“可计算的”，通过公式计算命中率

100*last("redis.info.value[keyspace_hits]",0)/(last("redis.info.value[keyspace_hits]",0)+last("redis.info.value[keyspace_misses]",0))
