浅谈Redis服务的集中监控

本文主要介绍在centos6.3上redmon和redis-live两款开源软件的使用情况，前者基于ruby，后者则基于python，从部署难度和功能上，我更青睐于后者！

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

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

3：通过rvm安装ruby

# /usr/local/rvm/bin/rvm install 1.9.2
# /usr/local/rvm/bin/rvm alias create default ruby-1.9.2-p320
# /usr/local/rvm/bin/rvm list
rvm rubies
=* ruby-1.9.2-p320 [ x86_64 ]
# => - current
# =* - current && default
# * - default
# ruby -v
ruby 1.9.2p320 (2012-04-20 revision 35421) [x86_64-linux]

4:通过gem安装bundler

# gem install bundler

5：通过git获取redmon源代码并安装

# git clone https://github.com/steelThread/redmon.gitInitialized empty Git repository in /root/redmon/.git/ remote: Counting objects: 975, done. remote: Compressing objects: 100% (506/506), done. remote: Total 975 (delta 483), reused 928 (delta 436) Receiving objects: 100% (975/975), 2.57 MiB | 714 KiB/s, done. Resolving deltas: 100% (483/483), done.

# grep -A 4 'option :redis_url' redmon/bin/redmon option :redis_url, :short => '-r URL', :long => '--redis URL', :default => 'redis://192.168.1.78:6377', :description => "The Redis url for monitor (default: redis://192.168.1.78:6377)"

# grep -A 9 'class Config' redmon/lib/redmon/config.rb  class Config DEFAULTS = { :namespace => 'redmon', :redis_url => 'redis://192.168.1.78:6377', :app => true, :worker => true, :web_interface => ['0.0.0.0', 4567], :poll_interval => 10, :secure => false }

# cd redmon/ # bundle exec /root/redmon/bin/redmon >> Maximum connections set to 1024 >> Listening on 0.0.0.0:4567, CTRL+C to stop [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！

# rpm -ivh python-pip-0.8-1.el6.noarch.rpm
# pip-python install tornado
# pip-python install redis
# pip-python install python-dateutil
# pip-python install argparse
# git clone https://github.com/kumarnitin/RedisLive.git
