编译 agent 注意

1 编译时候需要带 CGO_ENABLED=0
( 建议使用 go1.14 编译)

CGO_ENABLED=0 go build -o bin/agent/falcon-agent ./modules/agent

2 编译前确认 vendor

github.com/toolkits/sys/cmd.go 41 ~ 44

//err = syscall.Setpgid(cmd.Process.Pid, cmd.Process.Pid)
//if err != nil {
//      log.Println("Setpgid failed, error:", err)
//}

3 确保 /usr/sbin/ss 文件位置正确 (centos5, 6, 7, 8) 已验证

在下面文件执行了硬编码， 否则 centos5 会报错 PortMetric()

github.com/toolkits/nux/portstat.go  

编译 graph 注意

graph 必须使用 centos6 系统执行编译否则无法在生产中正常运行 编译时候需要带 CGO_ENABLED=1
否则会遇到交叉编译错误问题 ( 建议使用 go1.14 编译)

CGO_ENABLED=1 go build -o bin/graph/falcon-graph ./modules/graph

编译 kafka_consumer 注意

必须使用 go1.16 编译

log vendor 修改

确保 vendor/github.com/coreos/go-log/log/fields.go 文件被修改
1 修改 full_time 满足公司格式要求

"full_time":  time.Now().Format("2006-01-02 15:04:05.999"),  // time of log entry

2 修改 logger.verbose = true 由于属于内部变量无法外部修改

logger.verbose = true

3.修复 vendor/github.com/toolkits/sys/cmd.go +43 避免 Setpgid failed 报错

graph db

alter table
  endpoint_counter
add
  index `t_create_counter`(`t_create`, `counter`);

4.修复 vm，忽略所有错误信息

vendor/github.com/ShellCode33/VM-Detection/vmdetect/common.go  

删除错误输出  
PrintError
PrintWarning

vendor/github.com/ShellCode33/VM-Detection/vmdetect/linux.go
删除 Print 错误信息

5.修改挂载点问题

Documentations

• Usage
• Open-Falcon API

Prerequisite

• Git >= 1.7.5
• Go >= 1.6

Getting Started

Docker

Please refer to ./docker/README.md.

Build from source

before start, please make sure you prepared this:

yum install -y redis
yum install -y mysql-server

NOTE: be sure to check redis and mysql-server have successfully started.

And then

# Please make sure that you have set `$GOPATH` and `$GOROOT` correctly.
# If you have not golang in your host, please follow [https://golang.ir/doc/install] to install golang.

#mkdir -p $GOPATH/src/github.com/open-falcon
#cd $GOPATH/src/github.com/open-falcon
#git clone https://github.com/open-falcon/falcon-plus.git

mkdir -p $GOPATH/src/github.com
cd $GOPATH/src/github.com
git clone [email protected]:vip-ops-sh/open-falcon.git

And do not forget to init the database first (if you have not loaded the database schema before)

cd $GOPATH/src/github.com/open-falcon/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

NOTE: if you are upgrading from v0.1 to current version v0.2.0,then. More upgrading instruction

mysql -h 127.0.0.1 -u root -p < alarms-db-schema.sql

Compilation

cd $GOPATH/src/github.com/open-falcon/falcon-plus/

# make all modules
make all

# make specified module
make agent

# pack all modules
make pack

• after make pack you will got open-falcon-vx.x.x.tar.gz
• if you want to edit configure file for each module, you can edit config/xxx.json before you do make pack

Unpack and Decompose

export WorkDir="$HOME/open-falcon"
mkdir -p $WorkDir
tar -xzvf open-falcon-vx.x.x.tar.gz -C $WorkDir
cd $WorkDir

Start all modules in single host

cd $WorkDir
./open-falcon start

# check modules status
./open-falcon check

Run More Open-Falcon Commands

for example:

# ./open-falcon [start|stop|restart|check|monitor|reload] module
./open-falcon start agent

./open-falcon check
        falcon-graph         UP           53007

        falcon-alarm         UP           53063

• For debugging , You can check $WorkDir/$moduleName/log/logs/xxx.log

Install Frontend Dashboard

• Follow this.

NOTE: if you want to use grafana as the dashboard, please check this.

Package Management

We use govendor to manage the golang packages. Please install govendor before compilation.

go get -u github.com/kardianos/govendor

Most depended packages are saved under ./vendor dir. If you want to add or update a package, just run govendor fetch xxxx@commitID or govendor fetch [email protected], then you will find the package have been placed in ./vendor correctly.

Package Release

make clean all pack
