Documentations

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.org/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

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 v0.2.0(or above),then. More upgrading instruction

mysql -h 127.0.0.1 -u root -p < 5_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-alarm         UP           53063
  • For debugging , You can check $WorkDir/$moduleName/logs/xxx.log

Install Frontend Dashboard

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 [email protected] or govendor fetch [email protected], then you will find the package have been placed in ./vendor correctly.

Package Release

make clean all pack

    grafana配了0.2的api url, datasource

    在用grafana的singlestat面板时,数据展示有问题。 singlestat

    查看api调用的日志,发现里面查数据库用的是正则,

    例如'mem.memused'这个指标,用正则查的话,就会把mem.memused.percent也查出来 query

    急求falcon部分常见繁琐问题处理办法!!!

    各位大大好:

    1、目前alarm删除case的方式一次性十行还是不够效率,我想在mysql数据库中的alarm_case 直接删除数据,是否安全?副作用?

    2、服务器目前几千台,部分hostname变化或人为修改,导致太多垃圾endpoint,是否有自动清理或者手动清理endpoint无效值的方法。

  • Add arm64 support

    Add arm64 support

    Hi,

    I am checking on adding arm64 jobs in travis.

    I was trying to build the docker image for arm64 but it was failing with below error

    standard_init_linux.go:211: exec user process caused "exec format error"
    

    This package uses openfalcon/makegcc-golang:1.10-alpine as base image for building docker images which are not available for arm64. I am unable to find this image and its Dockerfile to add support for arm64.

    Travis Link for arm64 : https://travis-ci.com/github/odidev/falcon-plus/jobs/382607644

    I want to know whether you are planning on adding arm64 support and can I get any suggestions on adding arm64 support to Dockerfile and uploading it to docker hub?

    exit $rc
    

    我的mysql和redis是放在另一台服务器的,但是如果机房停电然后来电后,falcon的服务有可能起不来,自己用两台虚拟机模拟也可以,原因是mysql和redis的启动在falcon之后,falcon又依赖mysql和redis,否则falcon会有几个依赖这些的起不来,请问这种情况是否有什么办法解决呢?或者说falcon有类似于java的连接池之类的机制,让服务先起来等待mysql和redis启动,再正常接收数据,不影响服务先启动,否则服务起不来很不好维护。 当然如果有一些脚本能够对falcon的服务做监控来自动启动也可以,或者守卫之类的。
