你好的朋友们，我是新来的，很高兴认识您，希望您能为我提供帮助。我正在客户使用两种情况。一个我们在其Linux KVM基于kvm的虚拟机上有一个Nutanix，另一个我们具有运行VMware的常见X86服务器。objetive可以比较解决方案并确定最好的方法。（我们希望Nutanix最好是最好的！）它们在这两个上运行的应用程序都是3台虚拟机上的JBOSS系统。（应用程序，DB和一个Apache前端。）我使用Jmeter创建了一个录制测试，在该测试中，用户在Web界面中做了很多步骤（例如，搜索特定的人，单击菜单等）。该测试在X86服务器和VMware上运行良好，但是在Nutanix上，在150个用户之后，我总是开始：启动：0完成：0：0。而且CPU使用率也高于其他方案。几乎是双重的。我在虚拟机中添加了更多的CPU和RAM，但它不起作用。我也在非GUI模式下跑步，删除了听众，在“ MaxNewSize”中添加了更多内存，但似乎没有任何作用。您能告诉我是否还有其他事情可以解决此问题？

    您是否在“付费” Nutanix（例如NX，XC或HX系列平台）上运行此操作？还是Nutanix社区版？



    如果这是一个付费平台，请提交支持票，我们可以为您提供解决方案和绩效团队。这是我们针对此类应用程序的卓越中心，它们可以帮助调试出什么问题的详细问题，因此您不必做任何猜测。我们可以通过性能跟踪进行A | B测试，并确切找出瓶颈在哪里。之后，我们可以在此处愉快地发布该案例的细节，以供其他人遵循。



    如果这是Nutanix社区版，请告诉我们，我们可以潜入其中。

    \n

    \nIf this is a paid platform, please submit a support ticket, and we can get our solutions and performance team engaged for you. That is our center of excellence for apps like these, and they can help debug what's going wrong in detail, so that you dont have to do any guessing. We can run A|B testing with performance tracing, and find out exactly where the bottleneck is. After that, we can happily post the details of that case here for others to follow.

    \n

    \nIf this is Nutanix community edition, let us know and we can dive in.","quoteUsername":"Jon","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    - 很高兴能帮助你。



    一个想法，我敢肯定，您会被问到这一点，NX-3050在模型中有点旧，通常运行Sandy Bridge（Intel E5 V1）或Ivy Bridge（Intel E5 V2）。

    \nOne thought, and I'm sure you'll get asked this, NX-3050 is a bit older of a model, usually running Sandy Bridge (Intel E5 v1) or Ivy Bridge (Intel E5 v2).

    嗨，佩德罗，



    如果您可以，请让我们知道乔恩问的问题的答案以及您在集群上运行的AHV和NOS的版本。在苹果比较的苹果中，在性能方面，它们之间的区别不应太大。



    亲切的问候，



    迈克尔

    \n

    \nIf you could please let us know the answers to the questions that Jon asked and also the version of AHV and NOS that you have running on the cluster. In an apples for apples comparison there should not be much difference between them in terms of performance.

    佩德罗，很高兴提供帮助。



    是否在两个平台上的VM相同配置，您可以在每个VM（Web，App，DB）上在VCPU/MEM/存储配置上共享一些详细信息



    您提到了高CPU利用率，您正在使用哪种工具，并且它是具有高CPU利用率的特定VM吗？



    几件事要检查

    1.检查/验证VM是否在Nutanix群集中的不同节点上运行

    2.验证数据库未遇到任何暂停问题的峰值负载，僵局，阻止会话

    3.如果您可以在nutanix环境上运行“ rvtools”并上传/粘贴VM配置选项卡，这将很有帮助

    \n

    \nare the VM's same config on both the platforms, can you share some details on vCPU\/Mem\/Storage config for each VM (Web, App, DB)

    \n

    \nyou mentioned the high CPU utilization, what tool are you using and was it a particular VM having high CPU utilization ?

    \n

    \nCouple of things to check

    \n1. Check\/validate if the VMs are running on different nodes in the Nutanix cluster

    \n2. Verify during the peak load that database didnt run into any out of space issue, deadlocks, blocking sessions

    \n3. If you can run \"RVTools\" on the Nutanix environment and upload\/paste the VM config tab that would be helpful","quoteUsername":"murali-sriram","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

It doesn't generate IOPS too. I suppose it is because the application stops or gets too slow during the test, but I am not sure.



    - 具有高CPU使用率的VM是应用程序VM。-我正在使用工具Apache Jmeter 2.13来运行测试（在这种情况下，录制测试）。-VM的确在不同的节点上运行（前端和应用程序在一个中节点和数据库位于另一个节点中）仍在尝试使rvtools工作。将尽快发布信息。

    至少，我们希望将您的集群升级到最新的NOS和最新的AHV构建和重新测试。



    我们还希望在您正在运行的比较测试的Cisco/Dell Gear上获得确切的规格。



    升级到最新的NOS和AHV构建后，您可以在进行测试时可以运行一些性能跟踪脚本，这将捕获系统内部的所有内容。

    \nWe'll also want to get exact specifications on the Cisco\/Dell gear you are running comparison tests on.

    \nAfter you upgrade to the latest NOS and AHV builds, there are some performance tracing scripts that you can run while you do your tests, which will capture everything going on inside the system.","quoteUsername":"Jon","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    感谢您提供的详细信息，从问题的描述和当前的设置中，您指出的IOPS降至零，我怀疑您的JBOSS实例的JVM上的内存不足，并且您的垃圾收集正在消费所有CPU上的所有CPU应用层VM。

    当问题发生时，您可以检查JBOSS日志和JVM的大小吗？
