有个模版A，套用在机器m1、m2、m3

有个模版B，继承模版A，套用在机器m3

模版A、模版B中同样的监控项目，对m3的影响是怎样的。 这边认为同样的监控项目，模版B会覆盖模版A

是吗？

又如果模版B没有继承模版A。那么重复的监控项目对m3的影响又是怎样的？

有api就可以方便的和各自公司的CMDB做整合了

如果meta端配置了md5，那么updater的日志中会有如上的东东，wget部分。
updater无法正常更新agent。

另外，如果不更新agent的包名，是否无法正常更新agent？

配置中可以进行true or false，但是配置为false时依然不会收集数据，只有删除时才会收集数据

hbs http请求返回404 page not found

第一点：
1432691504.713948 [0 10.3.5.26:53515] "RPOP" "/queue/user/sms"
1432691504.714129 [0 10.3.5.26:53520] "RPOP" "/queue/user/mail"
为什么只看到alarm 在往redis中rporp数据，参照wiki是应该alarm往redis中push，然后sender进行pop么

第二点：
在alarm中的
"queue": {
"sms": "/sms",
"mail": "/mail"
},
"userSmsQueue": "/queue/user/sms",
"userMailQueue": "/queue/user/mail"
这4个队列对应是做什么用的
以及
"api": {
"portal": "http://falcon.example.com",
"uic": "http://uic.example.com",
"links": "http://link.example.com"
}
这些API地址只在什么时候去触发，用途是什么？

2015/05/31 02:53:05 scheduler.go:101: [DEBUG] stdout of plugin/sys/60_ping.py is blank

现象

• 哗, 又一家自主研发 云运维平台 的小伙伴了
• 但是,以往的 BAT 以及 Yahoo! 传说中的平台都是各种广告,神奇的截屏
• 可是,从来没有听说在公司以外有人用起来过

分析

• DevOps 平台,包含了太多硬嵌入的公司业务
• 以至根本无法简单的从平台中抽离出来
• 进而导致平台无法安装配置到其它业务场景中工作

建议

• 给出如何在 MAC/Win/Linux 平台上安装/调试/使用 的详细说明
• 就主机 <10 台的小微团队给出一个最小可用集
• 要知道, Google 也是从 2人团队发展起来的
• o-falcon 能进入越多的小微创业团队,意味着越多可能成为 Google 级别公司的核心运维平台 ;-)

judge先从hbs获取所有策略列表，静等Transfer的数据转发。 每收到一条Transfer转发过来的数据，立即找到这条数据关联的Strategy、Expression，然后做阈值判断。

alive类型的如果agent存在，会发送alive，如果agent不存在。应该judge就收不到alive数据，这时候judge怎么对这个类型做报警？

按文档安装Dashboard后，运行报错，望指导，多谢

 ./control start
I require gunicorn but it's not installed.  Aborting.

业务自己采集的数据，是采集一条就post到本机的agent，还是积攒一定数量再post。
我看文档中，plugin推荐是攒500条发送，业务自己采集的数据也推荐积攒一定数量再post么？

把heartbeat那项enabled设置为true， -->已修改，并重启./control restart
并配置上hbs的rpc地址 <--麻烦问下这个配置是在哪里配置。

mysql -uroot -pabc1234 -h127.0.0.1 ,都能正常连接mysql

mysql -ufalcon_portal -pabc1234 -h127.0.0.1 ,都能正常连接mysql

~agent就可以和hbs心跳了 ,这个有命令检查下吗，不知是是在哪配置错了，麻烦指点一，二，谢谢

策略表达式if后面可以使用哪些函数？如何使用等等

hi，在你们的文章中看到“transfer目前支持的业务后端，有三种，judge、graph、opentsdb。judge是我们开发的高性能告警判定组件，graph是我们开发的高性能数据存储、归档、查询组件，opentsdb是开源的时间序列数据存储服务”

我想请教下哪里可以看到你们的 graph 存储引擎的更多信息？另外，你们的时间粒度是固定的吗（例如 whisper 可以自定义 retentions = 10s:6h,1min:6d,10min:1800d）？

现在 screan 页面 能添加导航,不能修改和删除吗

安装绘图组件后，Dashboard/Screen无显示

数据分片是基于主机，还是基于监控项做分片？是不是同一个endpoint的数据都存在同一个graph上。在动态增删graph和transfer的时候，分片的数据是如何处理的，是否自动loadblance？

两个组件的http监听端口都是6060

有些主机已经不想监控了，但在dashborad一直存在挺闹心的
