你好,

在一个8节点集群的Prism中，我们在“运行状况”下收到一个警报，显示8个cvm中的3个的内存使用率为@ 100%，这大约持续了一周，如图(在Prism中)所示。然而，这些cvm在vCenter中似乎很好。在较高的级别上，cvm的Guest Mem %大约为40%或更少。

想法吗?

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?

    # cat /proc/meminfoWe将会检查这是否是一个值得担心的原因。

    您的集群运行的版本是什么?我也遇到过类似的问题，健康检查会因为CVM内存使用率高而变成黄色状态，并“卡住”——CVM内存使用率会下降并保持在低位，但警报可能会持续几天。

    集群运行状态为4.0.1.1。

    棱镜城的警报已经显示了好几周了。

    以下是cat /proc/meminfo的输出:

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

    谢谢rvillarin。似乎我们必须进一步挖掘集群状态和占用内存的进程。你最好和我们的支持团队一起立案调查。到目前为止，你在这个CVM上有大约5%的空闲内存，这有点令人担心，尽管这并不意味着某些东西会崩溃。
