  • vRealize Operation Manager Installation Pending on install.sh

    in ,

    If your company implemented firewall and blocked public NTP server, you may see installation of vRealize Operation Manager pending on ./install.sh on console. That’s because the installer tries to negotiate with NTP server www.iana.org. The firewall blocked the traffic. VMware TAM Manager Shan told me  there are two options on firewall to block traffic: REJECT…

  • Report Virtual Machines Powered Off More Than X Days in vROps

    in ,

    I got a request few weeks ago. Reporting virtual machines that powered off more than 3 days. I didn’t find out-of-box report in  vROps can do that. I had to create customized one. Following is how I did.

  • 在vROps中报表n天以前创建的快照

    in , ,

    有很多种方法可以用来做虚拟机快照报表。比如PowerCLI、VRTools、甚至vSphere Client本身也可以。今天我会分享如何使用vRealize Operations Manager (vROps) 6.x做自定义天数以前创建的虚拟机快照的报表。用vROps做表表的好处是可以通过计划任务自动以邮件形式发送报表，并提供PDF和CSV两种格式的表。 我在网上找到了一篇文章谈到如何用vROps实现类似报表。但要求修改vROps的规则，这可能会影响到vROps的全局计算模型。如果你的团队们需要为各自的报表设置不同的条件怎么办？

  • Report snapshots older than X days in vROps

    in , ,

    There are several ways to reporting snapshots. You can use PowerCLI, VRTools, or even vSphere Client itself. Today I will show you how to reporting by vRealize Operations Manager (vROps) 6.x. The benefit of  vROps reports is you can schedule it by sending email with PDF & CSV reports. I found a post discuss how to…

  • vRealize Operations Management Pack for Cisco UCS Review

    in , ,

    Cisco UCS blade system is the best blade system I used so far. Whatever the hardware, software or support is perfect. I recommend leverage the system for primary system of virtualization. UCS blade system architecture is different with HP. I feel it more likes a network system. Fabric Interconnect (FI) modules exchange data between uplinks…

  • vRealize Operations Manager 6之Cisco UCS性能监控组件介绍

    in , ,

    思科UCS刀片系列是我至今用过最好的刀片系统。无论是硬件、软件还是技术支持都堪称完美。个人推荐在大型虚拟化机房里把思科UCS作为主要设备。思科UCS刀片系统的架构和惠普的完全不同，感觉更像是个网络设备。Fabric Interconnect (FI)模块负责上联口和内部各组件之间的数据交换、IOM负责各刀箱数据路由。架构看起来很复杂，但是在管理大型数据中心时非常强大。说到大型数据中心，比如有 上百个刀箱和刀片服务器，数据要经过FI、IOM、刀片等，问题可能发生在任何层面，大型虚拟化数据中心很难找到问题的根源。UCS Manager有提供类似思科网络交换机一样的计数器功能，可以显示每一个端口的计数情况，但是这个监控工具不会告诉你什么时间、在哪个层面发生了问题 。在测试NetApp存储性能监控组件之前我有幸测试了vRealize Operations Manager 6的Cisco UCS性能监控组件。该组建同样由Blue Medora开发。以下简单介绍一下，只是我的个人观点 。

  • vRealize Opertion Manager 6之NetApp存储性能监控组件介绍

    in , , ,

    vRealize Operation Manager 6 （又叫vROps）是vCenter Operation Manager的全新版本，我从vCenter Operation Manager还是1.0时就开始使用了，很喜欢自我学习和动态阀值这两个功能。但是这款产品只能监控虚拟层面，如果可以监控存储层面就完美了。在比较大的vSphere环境中虚拟机是共享ESXi数据存储（datastore）的，如果少数虚拟机产生很高的IO，可能会影响到其他处于同一个存储上的虚拟机。想象一下，如果你有100个LUN跑在一个NetApp存储上，300个虚拟机在使用这100个LUN，某日用户说他们的虚拟机很慢，但是他们并没有跑什么应用，这时候就会比较难判断到底是哪儿出了问题，因为虚拟机可能共享同一个数据存储（datastore），数据存储存建于LUN上，LUN 可能来自某个聚合（Aggregate），并且多个LUN可能来自同一个物理磁盘。vCenter Operation Manager 在5.x时代有提供一款NetApp存储监控组件，但问题是很难把vSphere的数据存储（Datastore）和NetApp存储的设备关联起来。

  • NetApp Management Package for vRealize Operation Manager 6

    in , ,

    vRealize Operation Manager 6 (aka vROps) is new generation of vCenter Operation Manager. I started to use vCenter Operation Manager since version 1.0. I like the idea of self-learning and dynamic threshold. But the product only monitors virtualization layer. It would be perfect if it’s able to monitor under layer storage. In large vSphere environment,…

  • 新建的Super Metric不显示

    in ,

    今天在vRealize Operation Manager 6.0创建了几个super metric，主要用来计算ESXi主机的物理链路吞吐量。结果发现这些super metric只是出现在部分主机里。估计是有什么bug。快速解决的办法是重启一下vROps vApp。

  • New Created Super Metric Doesn’t Appear for Objects

    in ,

    Today I created few super metrics on vRealize Operation Manager 6.0 to calculate throughput of physical links on ESXi host. The super metrics just present to part of the selected hosts. I guess it’s some kind of minor bug. A reboot of vROps vApp can works around it. Just heads up.
