open-falcon监控系统
官方文档 https://book.open-falcon.org/zh/intro/index.html
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
1、系统环境
[root@ open -falcon-server ~] # cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core) |
2、系统优化
#安装下载软件 yum install wget -y #更换aliyun源 mv /etc/yum .repos.d /CentOS-Base .repo /etc/yum .repos.d /CentOS-Base .repo.backup wget -O /etc/yum .repos.d /CentOS-Base .repo http: //mirrors .aliyun.com /repo/Centos-7 .repo #下载epel源 yum install epel-release.noarch -y rpm -Uvh http: //mirrors .aliyun.com /epel/epel-release-latest-7 .noarch.rpm yum clean all yum makecache #下载常用软件 yum install git telnet net-tools tree nmap sysstat lrzsz dos2unix tcpdump ntpdate -y #配置时间同步 ntpdate cn.pool.ntp.org #更改主机名 hostnamectl set - hostname open -falcon-server hostname open -falcon-server #开启缓存 sed -i 's#keepcache=0#keepcache=1#g' /etc/yum .conf grep keepcache /etc/yum .conf #关闭selinux sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config setenforce 0 #关闭防火墙 systemctl stop firewalld.service systemctl disable firewalld.service |

4、初始化MySQL表结构(备注:导入表结构后,注意检查)
cd /tmp/ && git clone https: //github .com /open-falcon/falcon-plus .git cd /tmp/falcon-plus/scripts/mysql/db_schema/ mysql -h 127.0.0.1 -u root -p < 1_uic-db-schema.sql mysql -h 127.0.0.1 -u root -p < 2_portal-db-schema.sql mysql -h 127.0.0.1 -u root -p < 3_dashboard-db-schema.sql mysql -h 127.0.0.1 -u root -p < 4_graph-db-schema.sql mysql -h 127.0.0.1 -u root -p < 5_alarms-db-schema.sql rm -rf /tmp/falcon-plus/ |

5、配置Go语言开发环境
#安装go语言开发包(备注:安装需要epel源)
1
|
yum install golang -y |
#检查版本
[root@ open -falcon-server ~] # go version go version go1.8.3 linux /amd64 |
#查看go的安装路径
[root@ open -falcon-server ~] # find / -name go /etc/alternatives/go /var/lib/alternatives/go /usr/bin/go /usr/lib/golang/src/cmd/go #需要的是这个路径 /usr/lib/golang/src/go /usr/lib/golang/bin/go /usr/lib/golang/pkg/linux_amd64/go |
#设置环境变量GOROOT和GOPATH
export GOROOT= /usr/lib/golang export GOPATH= /home |
6、下载编译好的二进制版本

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”。

[root@ open -falcon-server open -falcon] # cd /home/work/open-falcon #启动服务 [root@ open -falcon-server open -falcon] # ./open-falcon start [falcon-graph] 25682 [falcon-hbs] 25691 [falcon-judge] 25699 [falcon-transfer] 25705 [falcon-nodata] 25711 [falcon-aggregator] 25718 [falcon-agent] 25726 [falcon-gateway] 25733 [falcon-api] 25739 [falcon-alarm] 25751 #检查服务启动状态 [root@ open -falcon-server open -falcon] # ./open-falcon check falcon-graph UP 25682 falcon-hbs UP 25691 falcon-judge UP 25699 falcon-transfer UP 25705 falcon-nodata UP 25711 falcon-aggregator UP 25718 falcon-agent UP 25726 falcon-gateway UP 25733 falcon-api UP 25739 falcon-alarm UP 25751 |
#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/work export WORKSPACE=$HOME /open-falcon mkdir -p $WORKSPACE cd $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-virtualenv yum install -y python-devel yum install -y openldap-devel yum install -y mysql-devel yum 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 $WORKSPACE /dashboard/ virtualenv . /env source env /bin/activate #如果安装了高版本pip,请先卸载pip uninstall pip 再按两次y #指定源安装包(备注:这步如果安装不成功,请检查pip版本是否为pip-9.0.1) pip install -r pip_requirements.txt -i |
4、先安装ez_setup.py,再安装pip
#下载ez_setup.py wget --no-check-certificate https: //bootstrap .pypa.io /ez_setup .py python ez_setup.py --insecure #下载pip wget https: //pypi .python.org /packages/11/b6/abcb525026a4be042b486df43905d6893fb04f05aac21c32c638e939e447/pip-9 .0.1. tar .gz #md5=35f01da33009719497f01a4ba69d63c9 #解压并安装 tar xf pip-9.0.1. tar .gz cd pip-9.0.1 python setup.py install cd .. |
#配置环境变量 (备注:这步不需要操作了)
#查看pip路径 [root@prometheus dashboard] # which pip /usr/bin/pip #配置pip环境变量 [root@prometheus dashboard] # vi /etc/profile #pip path export PATH= "/usr/bin/pip/bin:$PATH" #使环境变量生效source /etc/profile #测试是否可用 [root@prometheus dashboard] # pip Usage: pip < command > [options] Commands: install Install packages. download Download packages. uninstall Uninstall packages. freeze Output installed packages in requirements format . list List installed packages. show Show information about installed packages. check Verify installed packages have compatible dependencies. search Search PyPI for packages. wheel Build wheels from your requirements. hash Compute hashes of package archives. completion A helper command used for command completion. help Show help for commands. |
