真是不细心,才注意到http://community.zenoss.org/blogs/zenossblog/2011/12/19/hardcore-4,这篇博文的存在。看来,Zenoss 4并不只是传说了。
下面,我结合官方的ppt,说说4带给我们什么?

State of Affairs
● 3.x has been out for about 1.5 years
● about 70% of users on 3.x
● new UI is helping especially new users

是的,现在大家已经快忘却2.X的存在,用1年半的时候,足够消化掉对于2.X的认知。无论3.0或3.1上有多少BUG,但更多的童鞋都习惯了3的界面。

3.x Lifetime
● UI issues are resolved
● completed SNMPv3 support (incl. Traps)
● more pages transitioned

其实3.X的版本一直在改进中。就像之前的版本中,有这样或哪样的BUG一样。不过,3.2.1还算OK。

3.x Problems
● increased number of async. requests
● big number of components and devices
● lots of events

问题嘛 ,不多说了,用过的都懂得。

 

3.X的架构,不对,是以往的我们再熟悉不过的架构,也许是到了该说Bye的时候了。

Core 4: High Level Goals
● solve current problems
● prepare platform for the future
● improve reliability and scale
● provide further plugin points

Core 4的方向。

RRDCached
● lowered IO load
● improved collection capabilities per
collector

RRDCached的引入。提高RRD的IO读取效率。这个嘛, 比较有用。

Common Collector Framework
● common functionality has been abstracted
● improved consitency across all collection

这个嘛,还没有看懂,也许Zenhub一统数据的时代,也将过去。

RelStorage and memcached
● CMDB/Zope data is no longer stored in flat file but
MySQL instead
● MySQL 5.5.15+ required to take advantage of new
InnoDB plugin
● memcached for intermediary/shared cache for all
clients of CMDB/Zope data

这个嘛,狠!再也不骨ZODB了,对象管理将将由5.5的MYSQL来完成。想不通,这与其它开源工具在管理结构上,还有什么差别。不过也有好一面,至少不再为蛋痛的ZODB的读写再费脑筋了。
PS:为什么不尝试NoSQL?!

Re-written Event System
● RabbitMQ as event system backbone
● multi-stage/process event pipeline
● Lucene index backed event store
● multi-threaded Java based event service with REST api

真的对MYSQL很有信心吗?!


这下看明白了吧,呵呵。新的架构,童鞋们,继续学习吧~

Core 4 Timelines
● code available for build in January
● alphas available at roughly the same time
● release end of February
● move to Github and JIRA April/March

最后,时间表,其实4真的离我们不远了。

个人还是比较期待的~哈~
