redis监控内存使用量脚本

网上看到一个监控redis内存使用量的脚本，觉得不错，记录一下

#!/bin/sh

USEDMEMORY_77=$(redis-cli -h 192.168.119.77 info memory | grep used_memory_human: | awk -F ':' '{print $2}')
USEDMEMORY_78=$(redis-cli -h 192.168.119.78 info memory | grep used_memory_human: | awk -F ':' '{print $2}')
USEDMEMORY_76=$(redis-cli -h 192.168.119.76 -p 6379 info memory | grep used_memory_human: | awk -F ':' '{print $2}')
USEDMEMORY_117=$(redis-cli -h 192.168.119.118 -p 6379 info memory | grep used_memory_human: | awk -F ':' '{print $2}')
USEDMEMORY_118=$(redis-cli -h 192.168.119.118 -p 7379 info memory | grep used_memory_human: | awk -F ':' '{print $2}')

for((i=1;i<$ARR_LENGTH;i++))
