&lt;p&gt;ITIL v3发布后，CMDB成了CMS中的一个数据库；而且，CMS中包括不止像CMDB这样的配置信息数据库，其实任何保存配置信息的数据库都算在CMS系统 内。既然是一个系统，所以它就不光包含数据还包含一套配套工具集合，通过这套工具，维护和使用配置信息。CMS为其他所有ITIL流程提供基础的配置信 息。它的结构如下图所示：&lt;/p&gt; &lt;div id="attachment_435" class="wp-caption alignnone" style="width: 668px;"&gt;&lt;img class="size-full wp-image-435" title="Comfiguration Management System" src="http://www.martinliu.cn/wp-content/uploads/2009/03/cms.jpg" alt="配置管理系统" height="413" width="658" /&gt;&lt;p class="wp-caption-text"&gt;配置管理系统&lt;/p&gt;&lt;/div&gt; &lt;p&gt;如果说上面这幅图比较还是比较抽象的话，那么请见下图：&lt;/p&gt; &lt;div id="attachment_436" class="wp-caption alignnone" style="width: 724px;"&gt;&lt;img class="alignnone size-full wp-image-437" title="bmc-atrium1" src="http://www.martinliu.cn/wp-content/uploads/2009/03/bmc-atrium1.jpg" alt="bmc-atrium1" height="449" width="714" /&gt;&lt;br /&gt;&lt;p class="wp-caption-text"&gt;CMS is a set of tools based on all configuration data&lt;/p&gt;&lt;/div&gt; &lt;p&gt;从上图中我们看到，CMS系统一共可以分为四层。上三层是核心CMDB数据库和相关配套工具，最低层Data层则是是所有配置信息的基础来源。从 ITIL v3的角度来说，只建设一个集中的CMDB数据库来存储所有的CI信息是不够的，CMS系统中必须能够包含和处理所有企业已有的各个系统中的配置数据。换 言之，CMDB建设的局限性在于，它只是配置信息数据化，或者说电子化的第一步。&lt;/p&gt; &lt;p&gt;当前依然有很多企业雄心勃勃的上马CMDB项目，不过切记在规划时，一定先好好阅读一下ITIL v3中和CMS相关的内容，适当调整项目的目标和预期总是好的，也可以规避一些项目风险。&lt;/p&gt; &lt;blockquote&gt;&lt;p&gt;CMDB不只是一个数据库那么简单，更不可能在服务台的数据库中建立几张表就可以搞定。从企业IT管理的全局出发，按照 ITIL v3的规范，建设CMS应该是所有ITIL项目的当务之急。CMS系统决不能遗忘过去，必须有效整个现有的各个配置信息数据源，无论其以何种形式存在。它 必须是一个开放的平台，能过最大限度的和其他任何配置信息的消费者（ITIL流程，以及任何需要获取配置信息的任何应用）整合，&lt;/p&gt;&lt;/blockquote&gt; &lt;p&gt;以上的一些是我对CMS建设的一些认识。如果要落地到项目上还不许经过一个痛苦的过程，那就是产品选型。选项的过程中可以注重一下几点：&lt;/p&gt; &lt;ul&gt;&lt;li&gt;可视化：配置项和之间的关系按拓扑形式展现&lt;/li&gt;&lt;li&gt;标准化：软件、硬件配置项都有完整标准的CTI信息&lt;/li&gt;&lt;li&gt;归一化：与现有各种配置管理系统核心共存同时CMS保持一份完整的户口记录，任何CI都有ID&lt;/li&gt;&lt;li&gt;集成化：CMS中的数据以图形或者裸数据等形式供其他相关消费者流程或者人员使用&lt;/li&gt;&lt;li&gt;联邦化：CMS核心数据库中不保存动态变化的配置信息（DB的最大连接数，网络设备所使用的syslog服务器地址），这些信息通过联邦管理让用户从其他相关的工具系统中查看到最新的数据。&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;最近可能还会接触一下CMDB的项目，其他经验总结待续。&lt;/p&gt;</description><thr:total xmlns:thr="http://purl.org/syndication/thread/1.0">0</thr:total><author>noreply@blogger.com (test)</author></item><item><title>It just looks like a Mac desktop</title><link>http://lzheng.blogspot.com/2009/02/it-just-looks-like-mac-desktop.html</link><category>Apple</category><category>linux</category><category>Mac OS</category><category>Ubuntu</category><pubDate>Mon, 2 Feb 2009 08:53:00 +0800</pubDate><guid isPermaLink="false">tag:blogger.com,1999:blog-2270677862205877381.post-4117518551485467326</guid><description>&lt;img title="http://www.apple.com.cn/getamac/whichmac/images/portables_macbookair20090106.jpg" src="http://www.apple.com.cn/getamac/whichmac/images/portables_macbookair20090106.jpg" alt="" align="left" height="170" width="264" /&gt;We all knows Mac OS X looks very nice, and works nice also. But, Mac can not be only system for you to use. Most of us are using Intel PC desktops and laptops. You can't have your cake and eat it too. Chinese saying says "鱼和熊掌不可得兼" . So, you might need a new Mac skin for your desktop, no matter MS Windows or Linux OS. I'd like share two tips, you can make a Mac desktop in  minutes.&lt;br /&gt;&lt;br /&gt;&lt;span style="text-decoration: underline;"&gt;&lt;strong&gt;For Windows: &lt;/strong&gt;&lt;/span&gt;FlyakiteOSX is a all-in-one package. It much more easier then making a Mac-buntu. Does it slow down you windows system? Of course, yes. it's just a little bit and acceptable for me.&lt;br /&gt;&lt;br /&gt;&lt;img class="alignnone" title="http://osx.portraitofakite.com/header.png" src="http://osx.portraitofakite.com/header.png" alt="" height="76" width="540" /&gt;&lt;br /&gt;&lt;br /&gt;&lt;span style="text-decoration: underline;"&gt;&lt;strong&gt;For Gnome Linux:&lt;/strong&gt;&lt;/span&gt;&lt;br /&gt;&lt;br /&gt;There is a open source prject on the SourceForge.net: &lt;a href="http://sourceforge.net/projects/mac4lin"&gt;http://sourceforge.net/projects/mac4lin&lt;/a&gt; You need download the package and un-tar it. A pdf document will walk you through every settings. I made my Mac-buntu just in 20 minutes. I do not like 'global meun' and widget, so I ingored them.  &lt;a name='more'&gt;&lt;/a&gt;&lt;br /&gt;&lt;br /&gt;My laptop is a dual boot Dell D630; with MS Windows Xp for work and Ubuntu for fun. Now, them all looks like Mac OS X Leopard.

参考这上面的说法也只能有一个模糊的感觉。&lt;br /&gt;&lt;br /&gt;看看电脑技术打发展历程：最早的电脑系统，主机系统，开放系统，群集，网格，云计算。前一段时间看过一个非常抢眼的标题“以后世界上将只有5台电脑”。SaaS是一个比较火热的和云计算相关的技术，我认为它像是在web2.0发展到一定阶段后Web应用的一个发展，这方面的强者为salesforce之流。Google和Salesforce不同的是，Google提供网上office套件的同时，还开发他的平台，并提供与之配套的 SDK。Amazon不提供应用也没有SDK，他只提供平台，平台上包括基本的计算和存储服务。Google和Amazon说起来算是基础架构作为一种服务。抛开云计算本身不谈，用户使用和访问的方式并没有发生变化，在任何一个web浏览器存在的地方都能使用或者管理到云计算。客户端的计算和存储能力再次此退化到零，这不能说不是计算机技术发展的返祖现象吧！哈哈～～我也快糊涂了！</description><thr:total xmlns:thr="http://purl.org/syndication/thread/1.0">0</thr:total><author>noreply@blogger.com (test)</author></item><item><title>opennms 1.6.1-1 quick start guide</title><link>http://lzheng.blogspot.com/2009/01/opennms-161-1-quick-start-guide.html</link><category>OpenNMS</category><category>yum</category><pubDate>Sun, 11 Jan 2009 08:58:00 +0800</pubDate><guid isPermaLink="false">tag:blogger.com,1999:blog-2270677862205877381.post-6796629721475288890</guid><description>&lt;img title="http://www.etproductions.com/images/start.jpg" src="http://www.etproductions.com/images/start.jpg" alt="" align="right" /&gt;&lt;br /&gt;&lt;br /&gt;本安装手册为纯命令版，如果有什么疑问清参考官方安装手册，或给本贴留言。&lt;br /&gt;&lt;br /&gt;[install yum on your Linux box]&lt;br /&gt;选择任意Linux系统，安装上yum工具，在命令行测试 yum -v&lt;br /&gt;&lt;br /&gt;[testing internet connection with those two URL]&lt;br /&gt;测试是否能上网，用浏览器分别打开这两个网址&lt;br /&gt;&lt;ol&gt;&lt;br /&gt;

/&gt;1）在某电信构思的招标的答疑过程中，我被问道：你们的系统能支持Linux么？我回答：能支持RHEL 4，5 , SLES. 哦，那你们就说说能支持通用UNIX系统了，我们需要能运行在RHEL，或者RedFlag上。&lt;br /&gt;&lt;span style="color: #800000;"&gt;&lt;strong&gt;&lt;em&gt;&amp;gt;&amp;gt;越来越多的用户考虑把IT管理系统安装部署到Linux平台上，并且认为这就是一种UNIX系统，他们以前在商业UNIX系统上的管理也使用经验都能适用于Linux系统。&lt;/em&gt;&lt;/strong&gt;&lt;/span&gt;&lt;br /&gt;&lt;br /&gt;2）一次用户告诉我他们实在是不能使用Tomcat做为中间件，来运行我们的应用系统，他们必须用BEA。因为他们只有BEA的中间件的管理员，没有Tomcat的管理员。如果上报一个带有Tomcat的系统的话，安全部门不会审批的，因为安全认证还没通过，Tomcat从安全部门的角度讲安全性低。&lt;br /&gt;&lt;span style="color: #800000;"&gt;&lt;strong&gt;&lt;em&gt;&amp;gt;&amp;gt;把BEA的管理员不当Tomcat的管理员是人员任用的严谨还是浪费？为什么商业应用比开源应用安全？其实用户自己人也说，这都是制度，他们也无能为力，IT变革势力似乎种弱于工作惯性。&lt;/em&gt;&lt;/strong&gt;&lt;/span&gt;&lt;br /&gt;&lt;br /&gt;对于中小企业来说，应用某个开源技术难度应该比大企业要小很多。不过大型企业在很多方面也逐渐有，主动应用开源技术的趋势。这在我以前的post中也提到过。从人才的角度和当今的形势看，社会上的linux高手，开源大师其实是越来越多，在经济不景气的当下，开源技术的应用从任何角度上看，可能企业都应该放它到议事日程上了。&lt;/div&gt;</description><thr:total

title="http://www.competencetoexcellence.co.uk/cartoon2.gif" src="http://www.competencetoexcellence.co.uk/cartoon2.gif" alt="" width="300" height="222" align="left" /&gt;上周一周都在广州，为中国最大的直销企业Amway做“Remedy Administration Part 2"的培训，这个培训是我今年第5次做；本周用户还给公司发来了感谢信，可见此次培训也是本年效果很好的一次。其实本月对我来说是一个培训月，第一周在新加坡接受一产品培训“BMC Configuration Automation For Network”；第二周在北京给‘中国人寿’做ITIL v3 Foundation的企业内训；第三周在广州，就是这个Remedy的培训。&lt;br /&gt;&lt;br /&gt;ITIL v3培训和Remedy培训是两个不同类型的培训，一个是最好实践IT管理方法论的培训；另外一个是Remedy系统管理和开发的课程。一个注重理论的讲解，另外一个是注重实际操作的介绍。不过从讲师的角度来说，培训的准备和整个过程的控制都是殊途同归的。&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;准备篇&lt;br /&gt;&lt;/strong&gt;对整课程内容的整体把握是至关重要的，必须对每一个module的内容谙熟于胸，这样才能控制整个培训课程的节奏，才能对时间做到从容地分配。特别是4～5天的培训，把所有的课程从头到尾贯彻为一个整体，不失课程的整体性，让学员有整体感，不觉得你教的内容没有逻辑、琐碎是非常重要的。所以需要在准备课程的时候就想好，每个module之间的衔接方式，要准备好review的问题，从这些问题中总结上一个module，平滑的过度到下一个module，增加课程内容直接的衔接，可以提高学员对内容的整体理解和掌握。&lt;br /&gt;&lt;br /&gt;&lt;a name='more'&gt;&lt;/a&gt;&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;领导篇&lt;br /&gt;&lt;/strong&gt;特别是做企业内训，企业方的领导如果能至开幕词那是最好不过了，他够让学员再次明确培训目标和培训的纪律等，给学员一定的学习压力，能是整个课程进行的有利保证。总的来说领导在此时应该帮忙唱一出黑脸，下面讲师讲的红脸就可以开始演出了。&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;教室篇&lt;br /&gt;&lt;/strong&gt;确认教室中的投影仪和其他设施都就绪。对于需要上机操作的培训来说，最好每一个都有一台电脑，电脑的硬件和软件配置都最好相同。确认硬件配置足够能跑虚拟机环境，至少2GB内存以上。虚拟机软件和培训用虚拟环境的部署是比较费时的一个工作，对于15个学员的课堂，至少需要半天时间准备。对于企业来讲，有条件最好不好在自己的办公室进行，应该到一个远离办公场所的环境进行；宾馆会议室、城外的培训中心或者度假村都是非常好的选择。&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;实例篇&lt;br /&gt;&lt;/strong&gt;对于ITIL课程的讲解来说实例的引用是至关重要的，实例可以是以前的项目经验，工具的经验，一个社会现象，甚至是一个小的故事或者笑话都可以。对于这种外国人总结的理论，人们初次学习就像是“外国人听京剧”一样。语言的gap是客观存在的，很难在短短几小时内，把别人总结了几年甚至十几年的经验给讲明白。客观的讲：每个讲师都只是演绎了一个自己的版本，为了保证这个版本的正确性，一定要阅读原版ITIL v3的出版物，把其中的实例最好能联系到中国国情，中国特色的例子。例如 ：需要讲明白&lt;strong&gt;KPI&lt;/strong&gt;（Key performance indicator ）和 &lt;strong&gt; CSF&lt;/strong&gt;（Critical Success Factors）的区别，我引用了三鹿奶粉事件的案例，蛋白质含量是一个KPI，如果只关注这个指标，而生产出了对BB有害的奶粉了，那么这种质量管理是很可怕的。对于IT管理来说也一样，某个流程没有KPI是不行的，然而没有CFS那可是万万不行的，process owner或者IT管理经理需要看到流程的CSF中的至少一项或多项得到实现和落实，需要两手抓，两种指标都合格。在Remedy培训的课程中，我改变上来就对系统的over view介绍，而是从一个HelloRemedy程序入手，保证所有人在5分钟之内都开发出了一个具有增删改查四种操作的应用，学员对Remedy的开发流程一下子就有了了解，和以前的编程经验一下就联系起来了，对课程中lab的兴趣一下就提高了一大截。&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;辅助文档篇&lt;br /&gt;&lt;/strong&gt;一定要高估你的学员的学习能力，大多数人都是勤奋好学的，特别是看上去相对年轻的学员。课堂的内容往往不能满足他们一周的求知欲。对于ITIL v3的培训，可以提供给学员最新的英文和中文的ITIL术语表各一份，我还给学员提供了ITIL v3 Quick Reference Guide，这些内容可以帮助对课本内容学习和认证考试的准备。对Remedy的培训，我提供了Remedy Action Request System 7.1最新的所有产品文档，release notes，install guide等等。能更多提供相关的文档是充实课程内容的一个辅助方式。&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;课堂管理篇&lt;br /&gt;&lt;/strong&gt;签到表的管理也是很重要的，一般需要让学员知道，最后的结果会发给他们的HR。课堂时间的管理主要是根据课程内容的进行来自由安排，在每一个Break和Lab的时候都需要用最醒目的方式，告知开始和结束的时间。我的最佳实践是，电脑接上投影之后，使用屏幕扩展显示的方式工作，在ppt的演示配置中设置，把演示内容投影到第二个显示设备上。这样你就有两个可以工作的桌面，两个独立的桌面，在投影仪显示的那个桌面上，用白底黑字醒目的提示break或者lab的其实时间。原本的桌面你还可以上网或者备课用。&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;工具技巧篇&lt;/strong&gt;&lt;br /&gt;基于上一个技巧，还需要强调的是：电脑接上投影之后，才可以在桌面的显示属性的设置中看到第二个显示器，并且在这时候才能启用投影作为第二个显示器，把桌面扩展到投影上。&lt;a href="http://www.blue1000.com/bkhtml/2008-11/60053.htm"&gt;&lt;img title="演示者视图" src="http://www.blue1000.com/upload/2008_11/081123015491102.gif" alt="" width="355" height="293" align="left" /&gt;&lt;/a&gt;如果显卡支持的话，一般在投影上显示的分辨率还是可以调节的，这就避免了桌面切换和桌面与投影支持分辨率不匹配的麻烦。在得到一个扩展桌面之后，投影会显示一个你空白桌面，背景图片和你的本机相同。这样在打开PPT之后，你在放映设置的菜单里就能看到相关对屏幕设置的选项；重要的是两个选项：1）投影的第二个显示器；2）显示演示者试图。第二个技巧是我以前的Manager教给我的，这个演示者视图是一个和ppt内容不同的视图，如图所示。我觉得有两个好处，一是在这个视图上有计时器，能知道你讲了多长时间，二是能看到ppt的注释部分。另外一个工具就是带激光的翻页器。它使你能够站在任何一个你觉得舒服的地方讲解，&lt;img title="翻页器" src="http://www.china-brand.net/files/200801/product/25/1199331118.gif" alt="" width="183" height="207" align="right" /&gt;试着走到学员中间去讲解，是一个不错的方式，这样能让学员听的更清楚，而且也能让你容易融入到学员中。如果你也想使用这个工具的话，记得在电脑包中记得带一个没有拆封的备用电池。我的翻页器，如果使用激光指示过多的话比较费电，所以我一般都多带一节电池。&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;课程考核篇&lt;/strong&gt;&lt;br /&gt;中国人都比较重视考试，考试的压力能很好的驱动学员的学习。在上两个培训中都有考核的部分，一个是ITIL V3的官方认证考试；另一个是考核是我设计的。为了配合Amway的培训考核需求需要，由于这个培训是不提供试卷考试的，我就设计了一个对Lab结果的评估作为考试内容。所以学员在最后一天把lab的结果导出成一个文件中交给我，我从课程的几个方面来评估他们的结果，给出一个具体的分数。&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;反馈篇&lt;/strong&gt;&lt;br /&gt;在课程进行的过程中，可以向学员，特别是用户方培训的负责人征求反馈意见，及时了解学员的接受程度和期望。通过这些反馈信息，对后面的课程进行方式和内容做合理的调整。从而保证最终学员和用户对课程的满意。对于讲师来说，课程各个内容的质量可以看做是KPI，而用户的反馈和最终认可就可以看做是CSF了。说白了作为讲师而言，咱不能让人觉得白花了钱。&lt;br /&gt;&lt;br

src="http://www.blueloop.net/images/itil-v3.gif" alt="" width="380" height="380" /&gt;&lt;br /&gt;&lt;br /&gt;上周给“中国人寿”做了ITIL V3 Foundation Training， 这是一个定制的企业内训，包括3天的理论学习，一天的‘BSM机场模拟沙盘演练’，最后一天进行ITIL V3 Foundation 认证考试。总的来说培训的效果还是非常不错的，学员基本上都能够理解和掌握ITIL v3的基本理论；在随堂的模拟考试后，能够针对一些题和我做非常深入的讨论。BSM机场模拟沙盘演练对于这群基本上比较年轻的学员来说成了一个非常热烈的培训环节，培训教室温度和气氛都比较热，一轮游戏跑下来以后，有些人就已经是满脸通红了；可见沟通也是一件力气活 :) 从学员们填写的反馈表的结果显示，他们对我的平均满意度是 4.35；呵呵这证明经过多日来的备课准备和以前的项目积累还是比较有效的，相信下次能够比这做的更好。&lt;a name='more'&gt;&lt;/a&gt;&lt;br /&gt;&lt;br /&gt;那么：什么人是需要参加ITIL V3培训的？我觉得IT部门的所有相关人员，都是有必要参加ITIL v3的基础培训，部分流程核心人员和管理人员需要继续参加更高级的培训。除非你认为：不需要应用ITIL作为IT服务管理的理论，而是应用的&lt;a href="http://forum.martinliu.cn/topic.php?id=8" target="_blank"&gt;其他方法论&lt;/a&gt;总之ITIL作为当今的“good practice”，通常它还是非常推荐一种武装思想的必备武器。&lt;br /&gt;&lt;br /&gt;ITIL培训还应该是整个实施过程中的一部不可缺少的部分，不同规格和内容的培训需要在不同阶段提交给组织的各个层面。有时候一些组织结构或者管理方法的调整和改进，一方面需要高层领导的大力关注和重视；更重要的是保证这个改进和改革的步伐能持续不断的推进下去。&lt;br /&gt;&lt;br /&gt;关于ITIL理论的持续性学习，其实企业内部也可以自己组织，可以对当前运作的或即将实施的特定的流程，进行回顾。主要是把定制和客户化之后的流程、角色、PKI，CFI等概念和涉及的流程工作说明做进一步深化。培训的组织可以是不举一个的，process owner应该和service manager一起运作和制定这些培训，确保企业内相关流程的有效性和效率。&lt;br /&gt;&lt;br /&gt;相信企业运用了更多的ITIL之后，还可以总结出更多自己的经验。初级阶段应该是缓慢上升的过程，当ITSM达到一定的成熟度后，在应用其他未实施流程，应该会更快。 今天还发现了一个不错的ITIL Blog ，分享一下 &lt;a href="http://itservicemngmt.blogspot.com/"

&lt;/strong&gt;OTRS和OpenNMS发布了新的集成手册  &lt;a href="http://www.opennms.org/index.php/OTRS_Integration"&gt;http://www.opennms.org/index.php/OTRS_Integration&lt;/a&gt; 这个Web Service的接口应该能做方便的集成了，没有试过，总之OpenNMS+OTRS应该是不错的组合，黄金搭档送给你，到~~&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;The SIRIOS 2.2 modules for OTRS 2.3 are released &lt;/strong&gt;SIRIOS 2.2模块发布了。我一直以为&lt;a href="http://www.otrs.com/en/produkte/sirios/" target="_blank"&gt;SIROS&lt;/a&gt;是非开源的项目，今天才知道它也是开源的哦，有空试试看。这个是专门为安全管理定制的，主要是去管理企业的安全事件。&lt;br /&gt;&lt;br /&gt;自从2008-08-05   &lt;strong&gt;OTRS 2.3.1 (Bora Bora) &lt;/strong&gt;发布之后，又发布了两个版本，2.3.2  和 2.3.3，这两个版本都是2.3.1的bug修复版，功能上没有增加。&lt;br /&gt;&lt;br /&gt;OTRS 2.3 中重大的改变如下：&lt;br /&gt;&lt;br /&gt;&lt;a name='more'&gt;&lt;/a&gt;&lt;br /&gt;&lt;br /&gt;# "Performance, Performance, Performance!"  系统性能提高&lt;br /&gt;* Data base- &amp;amp; code-improvements increase lead to a general performance gain of up to 20%.&lt;br /&gt;* The support of an indexed full text search has been added. The feature is disabled per default because additional disc space is needed. The expected performance gain is 50%.&lt;br /&gt;* Reduced reloads by using AJAX technology&lt;br /&gt;* Instead of an ongoing recalculating of the escalation time during the run time, it is only recalculated when it changes due to an event in OTRS. It is then being stored in the ticket object which allows a direct access of external reporting tools to the data base as well as a more efficient reporting on escalations. This will also lead into a substantial performance improvement.&lt;br /&gt;&lt;br /&gt;# Search Functionality 搜索功能&lt;br /&gt;* Support of logical expressions: ticket-, customer- and FAQ- search supports logical expressions, utilizing the AND, OR and ! operators as well as structuring expressions with parentheses.&lt;br /&gt;* Search for ticket numbers by using the Browser OpenSearch feature (OpenSearch format).&lt;br /&gt;* Search for ticket titles in the agent ticket search form and in the generic agent.&lt;br /&gt;* Search for ticket close time in the agent ticket search form and in the generic agent.&lt;br /&gt;&lt;br /&gt;# Ticket Zoom &amp;amp; Ticket Move 工单伸缩和移动&lt;br /&gt;* Expand/Collapse of articles: the article view can be expanded to display all articles at once.

This is a stable, production release that incorporates nearly three years of development.&lt;br /&gt;&lt;br /&gt;以上算是OpenNMS的广告语大家看看就是，需要注意的是一个企业级的产品实施费用是从很低的门槛一直到企业级的花费的。和其他的企业级解决方案的实施没有区别，差异在于，一个不同的许可证类型，此为开源许可证是也。&lt;br /&gt;&lt;br /&gt;The last production version, 1.2.0, was aimed to compete squarely with Hewlett-Packard's OpenView Network Node Manager product. This release builds upon that work to expand the reach of OpenNMS to other parts of the OpenView family as well as to provide an open source alternative to products such as Tivoli's Netcool.&lt;br /&gt;&lt;br /&gt;以上是OpenNMS的精神所在：OpenNMS一直在叫嚣这和OpenView, NetCool较量；这足以说明了它的勇气，和发展方向，它的创始人Tarus从一个人单枪匹马开始，到现在有一般人inhouse开发这个产品，自己全世界出差，如果说没有实现和商业产品的抗衡的话，我个人觉得他起码实现了一个所有开源参与者的梦想“为需要自己的人工作，为自己工作”&lt;br /&gt;&lt;br /&gt;OpenNMS 1.6.0 sports a redesigned user interface, a number of scalability improvements and increased integration with other products. OpenNMS now runs on Windows, in addition to most flavors of Linux, Solaris and Mac OS X.&lt;br /&gt;&lt;br /&gt;上面说的是新版的用户界面重新设计了，目前我还没有时间安装，回头装好了一定上图片，新版的稳定性得到提高并增加了和其他产品的集成。现在OpenNMS也能在Windows上运行了，在我看这是早晚的是，它是个纯Java的应用，移植不是什么难事，不过我不推荐在windows上完开源的产品，有点不伦不类的感觉，而且从原生态的Linux环境中才哪呢个够获取开源的全部优势。&lt;br /&gt;&lt;br /&gt;One of the major additions to the platform is the Alarms subsystem. OpenNMS can receive events from a number of sources, such as SNMP traps, syslog, TL/1, and custom scripts. A key can be configured for each event that will allow it to be turned into an alarm. Thus if a device is generating multiple, identical events, their number will be reduced into just a single alarm. This greatly reduces the amount of event "noise" that operators see.&lt;br /&gt;&lt;br /&gt;上面说告警子系统现在是增强了。OpenNMS能收到像是snmp trap，syslog， TL/1和自定义脚本发来的告警事件。某种键值能被设置，让一个事件能被出发成一个警报。报警事件经过了压制和降噪处理，较少了重复报的数量。&lt;br /&gt;&lt;br /&gt;In addition, automated actions can be performed on alarms. For example, events that signal problem resolution, or "up" alarms, can be matched with "down" alarms to automatically clear them. Event workflow can be built into the system by using these automations to manage the alarm list, thus freeing up the operators to focus on the most important issues.&lt;br /&gt;&lt;br /&gt;另外，对于一个警报来说，可以和一个自动化的动作配合，例如某些up事件能去清除对应的down事件。&lt;br /&gt;&lt;br /&gt;While OpenNMS contains a robust automated discovery system, when managing tens of thousands of nodes it is often preferred to allow an external system to determine what OpenNMS is to monitor. Thus OpenNMS 1.6.0 contains a new "model importer" feature that allows node, interface and service information to be imported directly into the system using data in an XML format. One company uses this method to manage over 70,000 devices with a single instance of OpenNMS.&lt;br /&gt;&lt;br /&gt;同时OpenNMS现在的自动发现系统非常强大哦，档管理一万个节点的时候，OpenNMS往往倾向于使用一个外部的系统来决定什么是需要OpenNMS监控的。在1.6中包括这样一个新功能‘模型导入’，他能把xml格式的节点和端口数据自己导入到OpenNMS系统中。曾经一个公司用这个方法管理这7万个节点，都在一套OpenNMS系统内，好家伙~~也就是说这个功能有了之后，你就可以不用一个节点的去发现了，往往有些机器发现的那会正好不在线，那就漏掉很多的机器了。&lt;br /&gt;Data collection saw many improvements as well. With the proper hardware, OpenNMS is able to collect over one million data points every five minutes. This data can be from SNMP (versions 1, 2c and 3), JMX, HTTP, or NSClient. The collected data can be exported via the web user interface. Reports showing the highest and lowest values for a particular set of data points (Top N Reports) can also be created, and 1.6.0 contains a vastly improved thresholding system. Thresholds can be generated on individual data points, combinations of data points, as well as a "relative change" such as when a value shows a sudden increase or decrease.&lt;br /&gt;&lt;br /&gt;数据的采集方面也有很多增强。利用一个合适的硬件，OpenNMS能够每5分钟把超过一百万的数据采集点采集一遍，要是采集稳定的话，这还是比较快的了。被采集的数据点可以使来自 snmp v1,2,3, JMX, http, nsclient。 采集来的数据能通过web界面到处了。这还是不错的功能，能有可能做一些系统之外的自定义报表了。自带的报表功能能够定制TopN的报表。OpenNMS现在的阀值管理系统也得到了增强。能为某一个数据点设置，也能为一组数据采集点，同时有了对 "relative change"的管理，也就是某个数据忽高忽低的管理，也即是某些瞬间的异常增的很高或降的很低。&lt;br /&gt;&lt;br /&gt;OpenNMS was originally designed for network service monitoring, and that functionality has been increased as well. New monitors for such things as Windows services are now available, as well as more advanced synthetic transactions. The Page Sequence Monitor was created to monitor a complete web-based transaction, while the Mail Transport Monitor determines the full round-trip availability of a mail service.&lt;br /&gt;&lt;br /&gt;OpenNMS天生是监控网络的。新增了很多monitor，例如windows服务监控，模拟交易监控。页面序列监控器用了监控一些列的web交易处理行为，还能通过Mail Transport Monitor 来确定邮件服务的可用性。&lt;br /&gt;&lt;br /&gt;Probably the biggest change was the development of distributed monitoring. Using a small Java webstart application installed on a remote system, OpenNMS is able to monitor service availability from the point of view of the remote system. Combined with the Page Sequence Monitor one can measure the user's experience when visiting a website from various remote locations.&lt;br /&gt;&lt;br /&gt;最大的变更在这个版本中是‘分布式监控’，使用一个小的安装在远处的一个主机上的Java Webstat应用，opennms能过过这个监控服务点看到远程的系统上采集的数据。结合页面序列监控功能，它可以实现这样的功能：在南北方，网通电信的网络中找四个点安装这个程序后，模拟从不同网络位置监控某个web网站上一系列功能页面的可用性。这就是所谓的模拟交易管理，是Web应用管理方面中当下不可缺少的环节。&lt;br /&gt;&lt;br /&gt;As OpenNMS was designed as a platform, there are numerous ways for external applications, both open and proprietary, to integrate with it. There is a new Trouble Ticketing API that allows for two-way communication between OpenNMS and a number of external ticketing systems such as Jira, Concursive (CentricCRM) and OTRS.&lt;br /&gt;像opennms这样的平台，可以提供给开源或者商业外部系统的接口。通过这些api的双向接口，你可以把报警事件送到外部的工单管理系统(事件管理流程平台)中，例如 Jira, Concursive (CentricCRM) and OTRS.、&lt;br /&gt;&lt;br /&gt;These are just a few of the new features available in 1.6.0.

&lt;li&gt;&lt;strong&gt;对service的重新定义&lt;br /&gt;&lt;/strong&gt;&lt;/li&gt;&lt;br /&gt; &lt;li&gt;&lt;strong&gt;对Service management &lt;/strong&gt;&lt;strong&gt;的重新定义 &lt;/strong&gt;&lt;/li&gt;&lt;br /&gt; &lt;li&gt;&lt;strong&gt;更强调&lt;/strong&gt;&lt;strong&gt;processes&lt;/strong&gt;&lt;strong&gt;是&lt;/strong&gt;&lt;strong&gt;闭环系统&lt;/strong&gt;&lt;/li&gt;&lt;br /&gt; &lt;li&gt;&lt;strong&gt;ITIL从此进入Good practice时代&lt;/strong&gt;&lt;/li&gt;&lt;br /&gt; &lt;li&gt;&lt;strong&gt;Generic Roles概念 ： process owner, service owner, process manager&lt;/strong&gt;&lt;/li&gt;&lt;br /&gt;&lt;/ol&gt;</description><thr:total xmlns:thr="http://purl.org/syndication/thread/1.0">0</thr:total><author>noreply@blogger.com (test)</author></item><item><title>It seems Twitter is using Amazona S3</title><link>http://lzheng.blogspot.com/2008/11/it-seems-twitter-is-using-amazona-s3.html</link><category>amazonaws</category><category>Cloud Computing</category><category>twitter</category><pubDate>Tue, 4 Nov 2008 09:17:00 +0800</pubDate><guid isPermaLink="false">tag:blogger.com,1999:blog-2270677862205877381.post-7915723615098401243</guid><description>I had changed background image of &lt;a href="http://twitter.com/zliu" target="_blank"&gt;Twitter&lt;/a&gt;&lt;br /&gt;&lt;br /&gt;Today I can not find this image on my laptop, so I have to save it back form my Twitter page.&lt;br /&gt;&lt;br /&gt;There is the URL of that image.  &lt;img class="alignnone" src="http://s3.amazonaws.com/twitter_production/profile_background_images/3002355/index_bg.gif" alt="" width="398" height="367" /&gt;&lt;br /&gt;&lt;br /&gt;http://s3.amazonaws.com/twitter_production/profile_background_images/3002355/index_bg.gif&lt;br /&gt;&lt;br /&gt;Now I realized colud computing is not too far away.</description><thr:total xmlns:thr="http://purl.org/syndication/thread/1.0">0</thr:total><author>noreply@blogger.com (test)</author></item><item><title>Some old stuff for sharing</title><link>http://lzheng.blogspot.com/2008/10/some-old-stuff-for-sharing.html</link><category>cacti</category><category>OpenNMS</category><pubDate>Wed, 29 Oct 2008 09:19:00 +0800</pubDate><guid isPermaLink="false">tag:blogger.com,1999:blog-2270677862205877381.post-1145936752739057249</guid><description>I think the following open source software resources could be helpful to you.&lt;br /&gt;&lt;br /&gt;本页面上是我认为可能对您有用的资源连接，目的是让您能以最小的时间和精力代价来体验开源软件。使用一个虚拟应用可能是一个比较方便的途径；有些开源应用做的非常体贴用户，软件提供ISO文件下载，通过这个ISO文件甚至能一键安装，在一个物理和虚拟的硬件上试用这个软件了。&lt;br /&gt;&lt;h3&gt;Virtual Appliances / 虚拟应用&lt;/h3&gt;&lt;br /&gt;&lt;ul&gt;&lt;br /&gt;
