棱镜中的CVM记忆使用量高

你好 -

在一个8节点群集上的Prism中，我们在健康状况下获得了一个警报，显示了8个CVM中的3个cvms，其内存使用量为 @ 100％，如图所示，大约一周（在Prism中）。但是，这些CVM在vCenter中看起来不错。在高水平上，CVM的访客MEM％约为40％或更少。

想法？

谢谢。

    \nIn Prism on an 8-node cluster, we are getting an alert under Health showing 3 of 8 CVMs that their Memory Usage are @ 100%, for about a week now as shown in the graph (in Prism). However, those CVMs seem fine in vCenter. At a high level, Guest Mem % for the CVMs are around 40% or less.
    \n
    \nThoughts?

    嗨，rvillarin，您能否从显示高内存使用量的CVM之一中获取以下命令的输出：＃CAT /PROC /MEMINFOWE会检查这是否是担心的原因。

    您的群集正在运行什么版本？我遇到了类似的问题，即健康检查会启动有关CVM高内存使用量并获得“卡住”的黄色状态 - CVM内存使用情况会恢复并保持降低，但警报可能会触发几天。

    群集正在运行4.0.1.1。

    它仍在棱镜中显示警报已有数周。

    这是CAT /PROC /MEMINFO的输出：

    \nIt's still showing the alert in Prism for weeks now.

    \nHere's the output of cat \/proc\/meminfo:

    感谢rvillarin。就像我们必须更多地研究群集状态和使用内存的过程一样。最好让您与我们的支持团队一起研究一个案件。现在，您在此CVM上有大约5％的自由记忆，这有点担心分解。
