redis内存分析工具redis-rdb-tools安装部署 项目地址https://github.com/sripathikrishnan/redis-rdb-tools 安装部署
安装Python2.7
下载redis-rdb-tools
git clone https://github.com/sripathikrishnan/redis-rdb-tools.git
安装redis-rdb-tools
pip2.7 install python-lzf
cd redis-rdb-tools
python2.7 setup.py install常见用法:
# 以json格式输出rdb --command json /var/redis/6379/dump.rdb# 以json格式输出模糊查找rdb --command justkeyvals --key user.* /var/redis/6379/dump.rdbuser003 fname Ron,sname Bumquist,
user001 fname Raoul,sname Duke,
user002 fname Gonzo,sname Dr,
user_list user003,user002,user001# 查找确定键信息redis-memory-for-key -s localhost -p 6379 -a mypassword person:1Key person:1

rdb -c memory --largest10 /app/redis/data/7000/dump.rdb
报错及解决方法
在redis-cluster模式下使用户出现如下报错将地址改为该键对应的地址即可
[rootTEST python2.7]# redis-memory-for-key -s 172.16.2.53 -p 7000 KEYNAMETEST

1、整个rdb文件的解析会导致CPU占用严重所以慎用
2、最好选择单键查询的方式不太消耗资源
3、如果需要解析某个rdb文件最好使用它的备份文件或者将文件导出到本地或者测试机进行解析
