Redis-audit工具使用(转)

在我的线上环境中，由于应用上对redis数据没有做冷热处理，所以经常会出现redis内存使用率居高不下的情况，一直以来都想知道都是什么样的数据比较消耗redis内存，就好比写一个sql语句放在数据库中运行，看各表占空间的大小情况然后排序下，这看上去蛮简单的一个功能，貌似在redis上还不容易实现，redis-audit工具基本上可以满足类似的需求。下面是简单的安装和使用介绍！

1:安装ruby

1 2 3 4 5 6 7 8 9 10

[root@db1 ~]# wget ftp://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.2-p0.tar.gz [root@db1 ~]# tar -zxvpf ruby-1.9.2-p0.tar.gz [root@db1 ~]# cd ruby-1.9.2-p0 [root@db1 ruby-1.9.2-p0]# ./configure  --prefix=/usr/local/ruby [root@db1 ruby-1.9.2-p0]# make && make install [root@db1 ruby-1.9.2-p0]# cd [root@redis2 ~]# grep PATH /root/.bash_profile PATH=$PATH:$HOME/bin:/usr/local/ruby/bin:$PATH export PATH [root@redis2 ~]# source /root/.bash_profile

2:安装rubygems

1 2 3 4

[root@db1 ~]# wget http://production.cf.rubygems.org/rubygems/rubygems-2.0.7.tgz [root@db1 ~]# tar zxvf rubygems-2.0.7.tgz [root@db1 ~]# cd rubygems-2.0.7 [root@db1 rubygems-2.0.7]# ruby setup.rb

3:使用gem安装bundler

1 2 3 4 5 6 7

[root@db1 rubygems-2.0.7]# cd [root@db1 ~]#  wget http://tokyo-m.rubygems.org/gems/bundler-1.3.5.gem [root@db1 ~]# gem install bundler -l Successfully installed bundler-1.3.5 1 gem installed Installing ri documentation for bundler-1.3.5... Installing RDoc documentation for bundler-1.3.5...

4:安装git

1 2 3 4 5 6 7

[root@db1 ~]# cat /etc/yum.repos.d/git.repo [puias-computational] name=PUIAS Computational baseurl=http://puias.math.ias.edu/data/puias/computational/5/x86_64/ enabled=1 gpgcheck=0 [root@db1 ~]# yum -y install git

5:使用git迁出redis-audit源代码，查看redis数据情况

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139

从实际使用的情况上看，当要分析采样的数据较多时，会出现timeout报错信息，目前尚不清楚如何处理！
