运维监控系统之Open-Falcon
一、Open-Falcon介绍
1、监控系统，可以从运营级别（基本配置即可），以及应用级别（二次开发，通过端口进行日志上报），对服务器、操作系统、中间件、应用进行全面的监控，及报警，对我们的系统正常运行的作用非常重要。
2、基础监控
CPU、Load、内存、磁盘、IO、网络相关、内核参数、ss 统计输出、端口采集、核心服务的进程存活信息采集、关键业务进程资源消耗、NTP offset采集、DNS解析采集，这些指标，都是open-falcon的agent组件直接支持的。
Linux运维基础采集项：http://book.open-falcon.org/zh/faq/linux-metrics.html
对于这些基础监控选项全部理解透彻的时刻，也就是对Linux运行原理及命令进阶的时刻。
3、第三方监控
术业有专攻，运行在OS上的应用甚多，Open-Falcon的开发团队不可能把所有的第三方应用的监控全部做完，这个就需要开源社区提供更多的插件，当前对于很多常用的第三方应用都有相关插件了。
4、JVM监控
对于Java作为主要开发语言的大多数公司，对于JVM的监控不可或缺。
每个JVM应用的参数，比如GC、类加载、JVM内存、进程、线程，都可以上报给Falcon，而这些参数的获得，都可以通过MxBeans实现。
使用 Java 平台管理 bean：http://www.ibm.com/developerworks/cn/java/j-mxbeans/
5、业务应用监控
对于业务需要监控的接口，比如响应时间等。可以根据业务的需要，上报相关数据到Falcon，并通过Falcon查看结果。
二、Zabbix、Nagios、Open-Falcon这3大开源运维监控工具的比较
三、Open-Falcon编写的整个脑洞历程

说明：Open-Falcon部署分为前端（客户端）和后端（服务端）
四、后端部署（服务端）
参考官方文档：https://book.open-falcon.org/zh_0_2/quick_install/prepare.html

7、修改配置文件cfg.json
坑：
部分模块依赖连接数据库，因为如果不修改配置文件，aggregator模块会出现无法启动，graph、hbs、nodata、api、alarm模块会出现开启不报错但是状态为开启失败的情况。
如果需要每个模块都能正常启动，需要将上面模块的cfg.json的数据库信息进行修改。根据本教程的配置，需要修改配置文件所在的目录：
| 模块 | 配置文件所在路径 |
| aggregator | /home/work/aggregator/config/cfg.json |
| graph | /home/work/graph/config/cfg.json |
| hbs | /home/work/hbs/config/cfg.json |
| nodata | /home/work/nodata/config/cfg.json |
| api | /home/work/api/config/cfg.json |
| alarm | /home/work/alarm/config/cfg.json |
1）修改aggregator的配置文件
vim /home/work/aggregator/config/cfg.json
mysql的root密码为空，则去掉“password”，若不为空，则用root密码替换“password”。
2）修改graph的配置文件
vim /home/work/graph/config/cfg.json
mysql的root密码为空，则去掉“password”，若不为空，则用root密码替换“password”。
3）修改hbs的配置文件
vim /home/work/hbs/config/cfg.json
mysql的root密码为空，则去掉“password”，若不为空，则用root密码替换“password”。
4）修改nodata的配置文件
vim /home/work/nodata/config/cfg.json
mysql的root密码为空，则去掉“password”，若不为空，则用root密码替换“password”。
5）修改api的配置文件
vim /home/work/api/config/cfg.json
mysql的root密码为空，则去掉“password”，若不为空，则用root密码替换“password”。
6）修改alarm的配置文件
vim /home/work/alarm/config/cfg.json
mysql的root密码为空，则去掉“password”，若不为空，则用root密码替换“password”。
8、启动后端模块

#更多的命令行工具用法
# ./open-falcon [start|stop|restart|check|monitor|reload] module./open-falcon start agent./open-falcon check falcon-graph UP 53007 falcon-hbs UP 53014 falcon-judge UP 53020 falcon-transfer UP 53026 falcon-nodata UP 53032 falcon-aggregator UP 53038 falcon-agent UP 53044 falcon-gateway UP 53050 falcon-api UP 53056 falcon-alarm UP 53063#For debugging , You can check $WorkDir/$moduleName/log/logs/xxx.log |
至此后端部署完成。
8、其它用法
#重载配置（备注：修改vi cfg.json配置文件后，可以用下面命令重载配置）
curl 127.0.0.1:1988/config/reload |
五、前端部署 （备注：在另外一台服务器上面操作）
1、创建工作目录
export HOME=/home/workexport WORKSPACE=$HOME/open-falconmkdir -p $WORKSPACEcd $WORKSPACE |
2、克隆前端组件代码
git clone https://github.com/open-falcon/dashboard.git |
3、安装依赖包
yum install -y python-virtualenvyum install -y python-develyum install -y openldap-develyum install -y mysql-develyum groupinstall "Development tools" -y |
坑：
#省略下面这三步不操作（备注：因执行virtualenv ./env；安装的pip版本为1.4.1，再用pip安装pip_requirements.txt文件中的软件。都会出现报错的情况，导致无法安装成功。主要原因就是pip版本的问题。）解决这个问题，请参考第4步#进入目录cd $WORKSPACE/dashboard/virtualenv ./envsource env/bin/activate#如果安装了高版本pip，请先卸载pip uninstall pip 再按两次y#指定源安装包（备注：这步如果安装不成功，请检查pip版本是否为pip-9.0.1） pip install -r pip_requirements.txt -i |
这里virtualenv ./env作用是创建一个新的python环境，详见：https://www.liaoxuefeng.com/wiki/0014316089557264a6b348958f449949df42a6d3a2e542c000/001432712108300322c61f256c74803b43bfd65c6f8d0d0000
source env/bin/activate会切换到这个环境下，之后进行pip安装：
./env/bin/pip install -r pip_requirements.txt -i https://pypi.douban.com/simple4、先安装ez_setup.py,再安装pip
#下载ez_setup.pywget --no-check-certificate https://bootstrap.pypa.io/ez_setup.pypython ez_setup.py --insecure#下载pipwget https://pypi.python.org/packages/11/b6/abcb525026a4be042b486df43905d6893fb04f05aac21c32c638e939e447/pip-9.0.1.tar.gz#md5=35f01da33009719497f01a4ba69d63c9#解压并安装tar xf pip-9.0.1.tar.gz cd pip-9.0.1python setup.py installcd .. |

#启动服务
#启动服务有两种方法：法一：(env)[root@Open-Falcon-client dashboard]# bash control startfalcon-dashboard started..., pid=40853法二：(env)[root@Open-Falcon-client dashboard]# ./control startfalcon-dashboard started..., pid=40853#查看日志(env)[root@Open-Falcon-client dashboard]# ./control tail[2017-10-29 15:30:20 +0000] [40853] [INFO] Starting gunicorn 19.1.1[2017-10-29 15:30:20 +0000] [40853] [INFO] Listening at: http://0.0.0.0:8081 (40853)[2017-10-29 15:30:20 +0000] [40853] [INFO] Using worker: sync[2017-10-29 15:30:20 +0000] [40858] [INFO] Booting worker with pid: 40858[2017-10-29 15:30:20 +0000] [40863] [INFO] Booting worker with pid: 40863[2017-10-29 15:30:20 +0000] [40864] [INFO] Booting worker with pid: 40864[2017-10-29 15:30:20 +0000] [40866] [INFO] Booting worker with pid: 40866#退出env环境(env)[root@Open-Falcon-client dashboard]# deactivate[root@Open-Falcon-client dashboard]# |
由于我使用的系统centos6.9中,python让我升级为2.7版本，安装gunicorn之后，运行./control start后依旧报错" I require gunicorn but it's not installed."
说明系统找不到gunicorn，这里将gunicorn的路径加入到$PATH中得以解决
[root@localhost ~]# find / -name gunicorn /usr/local/python2.7/lib/python2.7/site-packages/gunicorn /usr/local/python2.7/bin/gunicorn [root@localhost local]# export PATH=$PATH:/usr/local/python2.7/bin
#访问网站
http://192.168.1.181:8081
#关于登录账号的问题或参考FAQ
请自行注册管理员用户名和密码
#登录界面
6、其它用法
#以开发者模式启动
./env/bin/python wsgi.pyopen http://127.0.0.1:8081 in your browser. |
#开启8081端口 （备注：如果关闭了防火墙，则直接忽略这步）
1）防火墙添加8081端口永久开放
firewall-cmd --add-port=8081/tcp --permanent
2）重新载入防火墙配置
firewall-cmd --reload
#停止dashboard运行
|

|
bash control stop |
#查看dashboard运行状态
|

|
bash control status |
六、FAQ
- Q: open-falcon v0.2 有管理员帐号吗？
- A: 可以通过dashboard自行注册新用户，第一个用户名为root的帐号会被认为是超级管理员，超级管理员可以设置其他用户为管理员。
- Q: open-falcon v0.2 dashboard 可以禁止用户自己注册吗？
- A: 可以的，在api组件的配置文件中，将
signup_disable配置项修改为true，重启api即可。
