GetInfoForPid fetches and parses the process information of the process identified by pid from /proc/[PID]/stat.

GetPIDState returns the state of a given PID It will return ErrProcNotExist if the process was not found.

GetProcCPUPercentage returns the percentage of total CPU time consumed by the process during the period between the given samples.

GetProcMemPercentage returns process memory usage as a percent of total memory usage.

GetSelfPid returns the process we're running as.

ListStates is a wrapper that returns a list of processess with only the basic PID info filled out.

Dead state, on linux this is both "x" and "X".

DiskSleep is uninterruptible disk sleep.

ErrProcNotExist indicates that a process was not found.

Idle state.

CPUTicks is a formatting wrapper for `tick` metric values.

CPUTotal is the struct for cpu.total metrics.

IncludeTopConfig is the configuration for the "top N processes filtering" feature.

MemBytePct is the formatting struct for wrapping pct/byte metrics.

NonFatalErr is returned when there was an error collecting metrics, however the metrics already gathered and returned are still valid.

ProcsTrack is a thread-safe wrapper for a process Stat object's internal map of processes.

Stats stores the stats of processes on the host.

PidState are the constants for various PID states.

ProcCallback is a function that FetchPid* methods can call at various points to do OS-agnostic processing.
