Redis服务的集中监控

一：redmon的安装和使用
1:安装rvm，rvm是ruby version manager的缩写，ruby语言是鬼子弄出来的，虽然不是程序员，我也一直不待见，真心觉得难用！

#bash < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)  
# echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bash_profile  

2:查看可用的ruby版本

1. # /usr/local/rvm/bin/rvm list known

3：通过rvm安装ruby

1. # /usr/local/rvm/bin/rvm install 1.9.2   
2. # /usr/local/rvm/bin/rvm alias create default ruby-1.9.2-p320  
3. # /usr/local/rvm/bin/rvm list  
4. rubies
5.  
6. =* ruby-1.9.2-p320 [ x86_64 ]  
7.  
8. >
9. # =* - current && default  
10. #  * - default  
11.  
12. # ruby -v  
13. ruby 1.9.2p320 (2012-04-20 revision 35421) [x86_64-linux]

4:通过gem安装bundler

1. # gem install bundler

5：通过git获取redmon源代码并安装

1. # git clone

https://github.com/steelThread/redmon.git

1. Initialized empty Git repository in /root/redmon/.git/ 

1. remote: Counting objects: 975, done. 

1. remote: Compressing objects: 100% (506/506), done. 

1. remote: Total 975 (delta 483), reused 928 (delta 436) 

1. Receiving objects: 100% (975/975), 2.57 MiB | 714 KiB/s, done. 

1. Resolving deltas: 100% (483/483), done. 

1. # grep -A 4 'option :redis_url' redmon/bin/redmon

1.   option :redis_url,

1.     :short       => '-r URL',

1.     :long        => '--redis URL',

1.     :default     => 'redis://192.168.1.78:6377',

1.     :description => "The Redis url for monitor (default: redis://192.168.1.78:6377)"

1. # grep -A 9 'class Config' redmon/lib/redmon/config.rb

1.   class Config

1.     DEFAULTS = {

1.       :namespace     => 'redmon',

1.       :redis_url     => 'redis://192.168.1.78:6377',

1.       :app           => true,

1.       :worker        => true,

1.       :web_interface => ['0.0.0.0', 4567],

1.       :poll_interval => 10,

1.       :secure        => false

1.     }

1. # cd redmon/ 

1. # bundle exec /root/redmon/bin/redmon 

1. >> Maximum connections set to 1024 

1. >> Listening on 0.0.0.0:4567, CTRL+C to stop 

1. [12-09-25 11:03:20] listening on http#0.0.0.0:4567

6：web接口情况，使用上存在无法添加对多个redis实例的监控 

redmon监控安装参考下列文章，在此感谢作者分享！

二：redis-live的安装和使用，同redmon相比，添加多个redis实例监控显得非常容易！而且实时性强，大赞！
