Functions ¶
func ApplyProcInterrupts ¶
ApplyProcInterrupts applies the given cpuset to the given irq number.
func GetCPUInfo ¶
GetCPUInfo returns the CPUInfo of the host.
func GetIPVSStats ¶
GetIPVSStats returns the IPVSStats of the host.
func GetNetDev ¶
func GetNetDev() (map[string]procfs.NetDevLine, error)
GetNetDev returns the net dev of the host.
func GetNetSoftnetStat ¶
func GetNetSoftnetStat() ([]procfs.SoftnetStat, error)
GetNetSoftnetStat returns the net softnet stat of the host.
func GetNetStat ¶
GetNetStat returns the net stat of the host.
func GetNetTCP6 ¶
GetNetTCP6 returns the net TCP6 of the host.
func GetNetUDP6 ¶
GetNetUDP6 returns the net UDP6 of the host.
func GetPSIStatsForResource ¶
GetPSIStatsForResource returns the psi stats for the given resource.
func GetPidCgroups ¶
GetPidCgroups returns the cgroups of the given pid.
func GetPidCmdline ¶
GetPidCmdline returns the cmdline of the given pid.
func GetPidComm ¶
GetPidComm returns the comm of the given pid.
func GetProcInterrupts ¶
func GetProcInterrupts() (procfs.Interrupts, error)
GetProcInterrupts returns the proc interrupts of the host.
func GetProcMounts ¶
GetProcMounts returns the mounts of the given pid.
func GetProcStat ¶
GetProcStat returns the Stat of the host.
func GetSchedStat ¶
GetSchedStat returns the sched stat of the host.
func GetSoftirqs ¶
GetSoftirqs returns the softirqs of the host.
func GetTaskSchedWait ¶
https://docs.kernel.org/scheduler/sched-stats.html#proc-pid-schedstat schedwait unit: nanosecond
func NewProcFSManager ¶
func NewProcFSManager() *manager
NewProcFSManager return a manager for procfs
func ReadFileNoStat ¶
ReadFileNoStat uses io.ReadAll to read contents of entire file. This is similar to os.ReadFile but without the call to os.Stat, because many files in /proc and /sys report incorrect file sizes (either 0 or 4096). Reads a max file size of 1024kB. For files larger than this, a scanner should be used.
