当怪异变得怪异时。性能故障排除。

绩效问题通常始于管理员查看统计数据，挠头的背面并说“等等，什么？”的场景开始。

这个问题可以以多种方式表现出来，主要的斗争是找到同时经历问题的环境实体，并逐层查看环境。无论瓶颈都位于网络上，计算还是存储层，解决性能问题始终是一项乏味且耗时的任务。

这就是为什么Nutanix发表一篇文章（或两篇）来帮助您进行该过程的原因。在哪里寻找，寻找什么以及如何解释数字。

技术TOPX：ESXI性能故障排除

Performance issues usually begin with the scene of an administrator looking at statistics, scratching the back of the head and saying \u2018Wait, what?\u2019<\/p>

The issue can manifest itself in so many ways and the main struggle is to find the entities of the environment that experience issues at the same time and look at the environment layer by layer. Whether the bottleneck lies on the network, compute or storage layer, troubleshooting performance issue is always a tedious and time-consuming task.<\/p>

That is why Nutanix published an article (or two) to help you with the process. Where to look, what to look for and how to interpret the numbers.<\/p>

@gabrielpaganabarcan您的意思是关于存储性能故障排除的文章吗？

我认为，如果您能够将其缩小到存储层，那么在Nutanix环境中，我希望看到一个特定的节点挣扎，该节点应该使您能够隔离主要贡献者，从而制定进一步的动作计划。另外，如果可以看到范围内的性能问题，我将查看问题的时间模式，并试图将其与可能的计划任务匹配。否则，群集可能不会应对负载。

我找不到有关存储性能故障排除的任何特定KB文章。您是否在环境中看到一个特定的问题？

@GabrielPaganAbarcan<\/user-mention> do you mean an article on troubleshooting storage performance?<\/p>

I think if you are able to narrow it down to storage layer then in a Nutanix environment I would expect to see a particular node struggling which should allow you to isolate the main contributor and thus develop a further plan of actions. Alternatively, if the performance issue is seen cluster-wide I would look at the time patterns of the issue spiking and attempt to match it to a possibly scheduled task. Otherwise, it is possible that the cluster is not coping with the load.<\/p>

\u00a0<\/p>

I was not able to find any particular KB article on troubleshooting storage performance. Is there a particular issue that you are seeing within your environment?<\/p>","quoteUsername":"Alona","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
