lintel::ProcessResourceData Struct Reference

#include <ProcessResourceReader.h>

Public Attributes
std::chrono::steady_clock::time_point	sampleTime = std::chrono::steady_clock::now()
std::optional< uint64_t >	cpuTicksTotal
std::chrono::seconds	uptime = std::chrono::seconds(0)
std::optional< double >	cpuPercent
std::optional< uint64_t >	memoryBytes
bool	valid = false

Detailed Description

Process resource snapshot read from the operating system (Linux /proc or macOS libproc). Values are optional / deltas so that only successfully read values are reported; missing values are never faked as zero.

Member Data Documentation

cpuPercent

std::optional<double> lintel::ProcessResourceData::cpuPercent

CPU usage in percent over the sampling delta, if two samples are available.

cpuTicksTotal

std::optional<uint64_t> lintel::ProcessResourceData::cpuTicksTotal

Cumulative process CPU time in clock ticks at sampling time.

memoryBytes

std::optional<uint64_t> lintel::ProcessResourceData::memoryBytes

Resident memory usage in bytes.

sampleTime

std::chrono::steady_clock::time_point lintel::ProcessResourceData::sampleTime = std::chrono::steady_clock::now()

Wall-clock sample timestamp used to compute elapsed time for a CPU delta.

uptime

std::chrono::seconds lintel::ProcessResourceData::uptime = std::chrono::seconds(0)

Process uptime.

valid

bool lintel::ProcessResourceData::valid = false

True if any field could be read successfully on this platform.
