console.log(process.resourceUsage());
Added in: v12.6.0
- Returns: <Object> the resource usage for the current process. All of these
values come from the
uv_getrusage
call which returns
a uv_rusage_t
struct.
userCPUTime
<integer> maps to ru_utime
computed in microseconds.
It is the same value as process.cpuUsage().user
.
systemCPUTime
<integer> maps to ru_stime
computed in microseconds.
It is the same value as process.cpuUsage().system
.
maxRSS
<integer> maps to ru_maxrss
which is the maximum resident set
size used in kilobytes.
sharedMemorySize
<integer> maps to ru_ixrss
but is not supported by
any platform.
unsharedDataSize
<integer> maps to ru_idrss
but is not supported by
any platform.
unsharedStackSize
<integer> maps to ru_isrss
but is not supported by
any platform.
minorPageFault
<integer> maps to ru_minflt
which is the number of
minor page faults for the process, see
this article for more details.
majorPageFault
<integer> maps to ru_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 to ru_nswap
but is not supported by any
platform.
fsRead
<integer> maps to ru_inblock
which is the number of times the
file system had to perform input.
fsWrite
<integer> maps to ru_oublock
which is the number of times the
file system had to perform output.
ipcSent
<integer> maps to ru_msgsnd
but is not supported by any
platform.
ipcReceived
<integer> maps to ru_msgrcv
but is not supported by any
platform.
signalsCount
<integer> maps to ru_nsignals
but is not supported by any
platform.
voluntaryContextSwitches
<integer> maps to ru_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> maps to ru_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.
