Centos下daemontools监控logstash进程

Logstash安装参考http://udn.yyuap.com/doc/logstash-best-practice-cn/get_start/daemon.html

首先用root用户，

$ yum install python-setuptools$ easy_install supervisor

然后可以查看具体的安装supervisord的版本：

$ supervisord --version3.3.0

利用easy install安装完后并不会创建一个Supervisor的配置文件，但幸运的是Supervisor包括一个通用的配置文件，然后可以

$ echo_supervisord_conf > /etc/supervisord.conf

在supervisord.conf添加要监测的文件：

[program:logstash_hy]command=/home/hadoop1/bms/logstash-1.5.4/bin/logstash -f /home/hadoop1/bms/logstash-1.5.4/conf/haiyun.conflogfile=/home/hadoop1/bms/logstash-1.5.4/logs/test.log

然后就可以启动supervisor，

/etc/init.d/supervisord -c /etc/supervisord.conf

使配置更改生效
每次修改主配置文件或增改子配置文件都需要执行supervisorctl update使新配置生效。或者用supervisorctl reload重新重新启动supervisor程序。

开启基于http的UI控制台

修改主配置文件 
vim /etc/supervisor/supervisord.conf，添加如下内容：
[inet_http_server]
port = 192.168.1.60:9001 ＃IP和绑定端口
username = admin ＃管理员名称
password = 123456 #管理员密码

这样，在浏览器中输入配置中写的地址和端口号，输入配置好的用户名和密码，便可以看到基于网页的控制台界面。从中，可以察看supervisor监控的>信息，可以察看进程的日志等。

这样就可以检测logstash的实时运行了

同时可以通过：supervisorctl查看管理监控的进程情况：
