首先,推荐在 github 上关注 falcon-plus,这样可以更方便的关注到项目的持续更新 。
全新的前端
- Open-Falcon 所有前端组件进行了统一整合,包括dashboard、screen、portal、alarm-dashboard、UIC、fe、links等统一整合到了 dashboard 组件;
- Dashboard 全站增加权限控制;
- Dashboard 增加删除指定 endpoint、counter 以及对应的 rrd 文件的功能;
- Dashboard 首页默认展示 endpoint 列表,并支持 endpoint 列表和 counter 列表翻页功能;
- Dashboard 增加删除一级 screen 的功能;
- 支持将报警的 callback 参数和内容在 Dashboard 页面上展示;
- 支持微信报警通道;
- Dashboard 支持展示过往的历史报警信息;
** demo请看等待补充...。**
统一的后端
- alarm支持报警历史信息入库存储和展示;
- 「报警合并」模块
links
的功能合并到统一前端 Dashboard 中,降低用户配置和维护成本; - 「报警发送」模块
sender
的功能合并到 alarm 中,降低用户配置和维护成本; - query的功能合并到了falcon-api组件中;
- 支持非周期性上报数据存储;
- agent支持通过自定义配置,只采集指定磁盘挂载点的磁盘监控数据;
- agent支持配置一个默认 tag,这样通过该 agent 上报的所有数据都会自动追加这个tag;
- judge新增报警判断函数
lookup(#num, limit)
,如果检测到过去num个周期内,有limit次符合条件就报警;
过去那些等待已久的bugfix
- 修复grafana不支持metric含有大写字母的bug;
- 修复agent写多个transfer高可用不生效的bug;
- 修复agent发送数据给transfer的超时设置不合理的问题;
全新的 RESTful API:让 open-falcon 没有难自动化的操作
- 发布了全新设计的组件 falcon-api,falcon-plus 所有的功能都可以通过 RESTful API 来完成;
- 统一前端 Dashboard 绝大部分功能都是通过 falcon-plus api 来实现;
最重要的一点:open-falcon v0.1 可以平滑升级到falcon-plus v0.2 !!!
如何从OpenFalcon v0.1 升级到 FalconPlus v0.2?
新增数据库表
cd $GOPATH/src/github.com/open-falcon/falcon-plus/scripts/mysql/db_schema/
mysql -h 127.0.0.1 -u root -p < alarms-db-schema.sql
NOTE:
- falcon-plus 如何编译,请参考 falcon-plus readme ;
- 或者直接下载官方编译好的二进制包;
现在正式开始升级之旅:)
1. 升级agent
用falcon-plus agent 二进制文件替换掉v0.1版本 agent 的二进制,同时注意修改agent的配置文件:
diff --git v0.1/agent/cfg.example.json v0.2/agent/cfg.example.json
--- v0.1
+++ v0.2
"backdoor": false
},
"collector": {
- "ifacePrefix": ["eth", "em"]
+ "ifacePrefix": ["eth", "em"],
+ "mountPoint": []
+ },
+ "default_tags": {
},
"ignore": {
"cpu.busy": true,
2. 升级transfer
用falcon-plus transfer 二进制文件替换掉v0.1版本 transfer 的二进制即可,配置文件无需变化。
3. 升级graph
用falcon-plus graph 二进制文件替换掉v0.1版本 graph 的二进制即可,配置文件无需变化。
4. 用api模块来代替query模块
- 停止query的运行;
- 从
make pack
得到的 tar.gz 包中解压得到 api 及其配置文件,检查配置文件如下,然后启动api组件即可。

}
其中db
部分为数据库连接信息相关,按需修改即可;graphs
部分为后端的graph列表信息,可以和v0.1版本的query cfg.json部分内容保持一致即可。
5. 升级hbs
用falcon-plus hbs 二进制文件替换掉v0.1版本 hbs 的二进制即可,配置文件无需变化。
6. 升级judge
用falcon-plus judge 二进制文件替换掉v0.1版本 judge 的二进制即可,配置文件无需变化。
7. 升级alarm
用falcon-plus alarm 二进制文件替换掉v0.1版本 alarm 的二进制,同时注意修改alarm 的配置文件:
diff --git v0.1/alarm/cfg.example.json v0.2/alarm/cfg.example.json
--- v0.1/alarm/cfg.example.json

NOTE: v0.2版本中,去除了sender模块,将sender模块的功能,合并到了alarm组件中,降低了用户的配置和维护成本; 同时增加了对微信的发送支持。
8. 升级aggregator
用falcon-plus aggregator 二进制文件替换掉v0.1版本 aggregator 的二进制,同时注意修改aggregator 的配置文件:
diff --git v0.1/aggregator/cfg.example.json v0.2/aggregator/cfg.example.json
--- v0.1/aggregator/cfg.example.json
