当内存百分比过高时，此规则将生成警报。

摘要

当特定进程消耗的内存过高时，此规则将生成警报。

注意:请注意，如果此规则的阈值与“进程监视: 运行状态收集”规则的相应阈值不同，则可能导致警报与进程运行状态之间不一致。

为了避免生成过多的警报，使用了规则的最小阈值。最小阈值的默认值为 7%。可通过重写在操作管理控制台中针对规则将阈值更改为任何值，但如果将其更改为低于 7% 的值，则默认情况下，有效阈值将为 7%。

用户可通过在适当代理和适当密钥上创建 MinimalMemoryPercentageThreshold 注册表 DWORD (32 位) 值来更改最小阈值。有效阈值将等于两个值的最大值: 通过操作管理控制台的默认/重写阈值和在注册表中设置的最小阈值。

以下注册表项用于最小阈值:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Operations Manager\3.0\Modules\Global\BaseOSProcessMonitoring
