process.resourceUsage()
-
返回:<Object> 当前进程的资源使用情况。所有这些值都来自返回

调用。¥Returns: <Object> the resource usage for the current process. All of these values come from the
uv_getrusage
call which returns auv_rusage_t
struct.-

majorPageFault
<integer> 映射到ru_majflt
,这是进程的主要页面错误数,请参阅 这篇文章了解更多详情。Windows 不支持此字段。¥
majorPageFault
<integer> maps toru_majflt
which is the number of major page faults for the process, see this article for more details. This field is not supported on Windows. -

swappedOut
<integer> maps toru_nswap
but is not supported by any platform. -
fsRead
<integer> 映射到ru_inblock
,这是文件系统必须执行输入的次数。¥

but is not supported by any platform. -
voluntaryContextSwitches
<integer> 映射到ru_nvcsw
,这是由于进程在其时间片完成之前(通常是为了等待资源可用)自愿放弃处理器而导致 CPU 上下文切换的次数。Windows 不支持此字段。¥
voluntaryContextSwitches
<integer> maps toru_nvcsw
which is the number of times a CPU context switch resulted due to a process voluntarily giving up the processor before its time slice was completed (usually to await availability of a resource). This field is not supported on Windows. -
involuntaryContextSwitches
<integer> 映射到ru_nivcsw
,这是由于较高优先级进程变得可运行或因为当前进程超出其时间片而导致 CPU 上下文切换的次数。Windows 不支持此字段。¥
involuntaryContextSwitches
<integer> maps toru_nivcsw
which is the number of times a CPU context switch resulted due to a higher priority process becoming runnable or because the current process exceeded its time slice. This field is not supported on Windows.
