大家好，我是讯享网，很高兴认识大家。

基础介绍

基于open-falcon的升级版,亮点:
新增组织目录树,管理更加方便;
新增告警策略条件表达式,与条件;
新增留观时长;

缺点:
当前正在高速迭代期,可能部分功能在高并发情况下会发生不可描述现象.
当前未与k8s贴合,流失k8s市场.
虽说开源,能满足运维日常监控,但要与自身业务紧密贴合,还需要有开发技术能力的基佬完成自身业务需求二次开发,

部署环境

go 环境安装与配置

下载 cd /opt && wget https://studygolang.com/dl/golang/go1.15.linux-amd64.tar.gz 解压 tar -zxvf go1.15.linux-amd64.tar.gz 重命名 mv go1.15.linux-amd64 go 配置go的工作空间 go的代码必须在GOPATH中，也就是一个工作目录，目录包含三个子目录 $GOPATH src 存放go源代码的目录,存放golang项目的目录，所有项目都放到gopath的src目录下 bin 在go install后生成的可执行文件的目录 pkg 编译后生成的，源码文件，如.a 创建 /opt/gocode/{src,bin,pkg}，用于设置GOPATH为/opt/godocer mkdir -p /opt/gocode/{src,bin,pkg} /opt/gocode/ ├── bin ├── pkg └── src 设置GOPATH环境变量 修改 /etc/profile 系统环境变量文件，写入GOPATH信息以及go sdk路径 [root@ZBX-PRMS go]# cat /etc/profile.d/go_profile.sh #!/bin/bash # Golang源代码目录，安装目录 export GOROOT=/opt/go # Golang项目代码目录 export GOPATH=/opt/gocode # Linux环境变量 export PATH=$GOROOT/bin:$PATH #go install后生成的可执行命令存放路径 export GOBIN=$GOPATH/bin 查看go环境变量路径 which go 查看go语言环境信息 go env 查看go版本，查看是否安装成功 go version

配置 go module 国内镜像

讯享网原生golang地址会被墙(GOPROXY="https://proxy.golang.org,direct"),无法get.使用阿里云的go镜像地址加速 go env -w GO111MODULE=on go env -w GOPROXY=https://mirrors.aliyun.com/goproxy/,direct

源码编译夜莺监控项目代码

# 该项目没有使用go module管理，需要放到github.com/didi下编译 echo $GOPATH /opt/gocode mkdir -p $GOPATH/src/github.com/didi cd $GOPATH/src/github.com/didi # clone代码并编译打包，pack时会自动build，打包成一个tar.gz git clone https://github.com/didi/nightingale.git 如本机未FQ,可能克隆比较慢,可以使用下列克隆方法尝试,50%几率会加速克隆(嘻嘻) git clone https://github.com.cnpmjs.org/didi/nightingale.git cd nightingale && ./control build && ./control pack

重载配置文件
nginx -t
nginx -s reload

修改配置文件

讯享网 
配置文件在etc目录，着重看一下mysql.yml，修改mysql访问的用户名和密码，另外redis密码默认为空，如果您配置了redis的访问密码，需要对应的修改monapi和judge的配置文件，将redis密码配置好。另外在etc/address.yml下可以看到各个模块监听的端口，如果与本地其他服务端口冲突了，就需要手工修改一下啦。 mysql.yml [root@10-255-0-183 etc]# cat mysql.yml --- uic: addr: "root:agc&P8m.@tcp(127.0.0.1:3306)/n9e_uic?charset=utf8&parseTime=True&loc=Asia%2FShanghai" max: 16 idle: 4 debug: false mon: addr: "root:agc&P8m.@tcp(127.0.0.1:3306)/n9e_mon?charset=utf8&parseTime=True&loc=Asia%2FShanghai" max: 16 idle: 4 debug: false hbs: addr: "root:agc&P8m.@tcp(127.0.0.1:3306)/n9e_hbs?charset=utf8&parseTime=True&loc=Asia%2FShanghai" max: 16 idle: 4 debug: false

启动各模块进程

讯享网 
发布包里默认提供了一个control脚本，用来启停服务，直接执行 ./control start all 即可启动所有模块，./control status 可以查看各模块进程是否都已启动，夜莺共有6个核心模块，注意一下进程数是否正确。最后安装一下nginx，nginx有个示例配置文件在etc/nginx.conf，注意修改pub目录指向真实路径。至此，单机版就部署成功了。访问nginx即可看到页面。如果发现nginx日志里出现权限报错，检查机器selinux配置，尝试关闭selinux解决。 setenforce 0 sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/sysconfig/selinux 使用服务方式启动 修改 etc/service 目录下的各个服务启动文件后复制到 /usr/lib/systemd/system 然后在 etc/service 目录下设置开机启动这些服务 [root@10-255-0-183 service]# systemctl enable *.service Created symlink from /etc/systemd/system/multi-user.target.wants/n9e-index.service to /usr/lib/systemd/system/n9e-index.service.

如果在全部对象页面看不到机器，或者看到了机器但是看不到监控数据，请检查所有的logs目录下的文件，一定可以找到线索。比如是不是ifconfig、route等命令缺失？少了net-tools库？机器环境的问题还请baidu解决哈~

Nightingale本身的核心模块不提供告警发送功能，只是把告警消息推送到redis里就算完事，因为不同公司的告警通道各异，有的希望用邮件接收、有的希望用短信，或者是电话、微信、钉钉、自研IM等，这块希望各公司自行适配，共建社区。邮件的发送有SMTP标准，所以初期可以使用邮件测试，这里提供一个邮件的发送模块：mail-sender 作为样例。

邮件告警通道模块配置

测试邮件模块是否正常工作

讯享网 
./mail-sender -t (改成自己常用的邮箱,如自己的邮箱)，程序会自动读取etc目录下的配置文件，发一封测试邮件给

使用告警策略测试邮件告警通道是否正常

讯享网 
在"告警策略"菜单中,新增一条告警策略,将阀值改成低于正常获取的值来测试邮件的发送功能是否正常 如 cpu.idle >= 1.00,该条件每一条都会满足,则可触发邮件告警 测试没问题后,将阀值改为正常值或删除测试的告警策略

邮件发送日志

讯享网 
发送的日志放在 logs/n9e-monapi 目录中,如邮件发送异常,则进入该目录查看具体详情日志
