Functions ¶
Types ¶
type IOCountersStat ¶
type IOCountersStat struct { ReadCount uint64 `json:"readCount"` WriteCount uint64 `json:"writeCount"` ReadBytes uint64 `json:"readBytes"` WriteBytes uint64 `json:"writeBytes"` }
func (IOCountersStat) String ¶
func (i IOCountersStat) String() string
type MemoryInfoExStat ¶
type MemoryInfoExStat struct { RSS uint64 `json:"rss"` // bytes VMS uint64 `json:"vms"` // bytes Text uint64 `json:"text"` // bytes Lib uint64 `json:"lib"` // bytes Data uint64 `json:"data"` // bytes Dirty uint64 `json:"dirty"` // bytes }
MemoryInfoExStat is different between OSes
func (MemoryInfoExStat) String ¶
func (m MemoryInfoExStat) String() string
type MemoryInfoStat ¶
type MemoryInfoStat struct { RSS uint64 `json:"rss"` // bytes VMS uint64 `json:"vms"` // bytes Swap uint64 `json:"swap"` // bytes }
func (MemoryInfoStat) String ¶
func (m MemoryInfoStat) String() string
type MemoryMapsStat ¶
type MemoryMapsStat struct { Path string `json:"path"` Rss uint64 `json:"rss"` Size uint64 `json:"size"` Pss uint64 `json:"pss"` PrivateClean uint64 `json:"privateClean"` PrivateDirty uint64 `json:"privateDirty"` Referenced uint64 `json:"referenced"` Anonymous uint64 `json:"anonymous"` Swap uint64 `json:"swap"` }
func (MemoryMapsStat) String ¶
func (m MemoryMapsStat) String() string
type NumCtxSwitchesStat ¶
type NumCtxSwitchesStat struct { Voluntary int64 `json:"voluntary"` Involuntary int64 `json:"involuntary"` }
func (NumCtxSwitchesStat) String ¶
func (p NumCtxSwitchesStat) String() string
type OpenFilesStat ¶
func (OpenFilesStat) String ¶
func (o OpenFilesStat) String() string
type Process ¶
type Process struct { Pid int32 `json:"pid"` // contains filtered or unexported fields }
func NewProcess ¶
NewProcess creates a new Process instance, it only stores the pid and checks that the process exists. Other method on Process can be used to get more information about the process. An error will be returned if the process does not exist.
func (*Process) CPUAffinity ¶
func (*Process) Cmdline ¶
Cmdline returns the command line arguments of the process as a string with each argument separated by 0x20 ascii character.
func (*Process) CmdlineSlice ¶
CmdlineSlice returns the command line arguments of the process as a slice with each element being an argument.
func (*Process) Connections ¶
func (p *Process) Connections() ([]net.ConnectionStat, error)
func (*Process) CreateTime ¶
func (*Process) IOCounters ¶
func (p *Process) IOCounters() (*IOCountersStat, error)
func (*Process) MemoryInfo ¶
func (p *Process) MemoryInfo() (*MemoryInfoStat, error)
func (*Process) MemoryInfoEx ¶
func (p *Process) MemoryInfoEx() (*MemoryInfoExStat, error)
func (*Process) MemoryMaps ¶
func (p *Process) MemoryMaps(grouped bool) (*[]MemoryMapsStat, error)
MemoryMaps get memory maps from /proc/(pid)/smaps
func (*Process) MemoryPercent ¶
MemoryPercent returns how many percent of the total RAM this process uses
func (*Process) NetIOCounters ¶
func (p *Process) NetIOCounters(pernic bool) ([]net.IOCountersStat, error)
func (*Process) NumCtxSwitches ¶
func (p *Process) NumCtxSwitches() (*NumCtxSwitchesStat, error)
func (*Process) NumThreads ¶
func (*Process) OpenFiles ¶
func (p *Process) OpenFiles() ([]OpenFilesStat, error)
func (*Process) Percent ¶
If interval is 0, return difference from last call(non-blocking). If interval > 0, wait interval sec and return diffrence between start and end.
func (*Process) Rlimit ¶
func (p *Process) Rlimit() ([]RlimitStat, error)
type RlimitStat ¶
type RlimitStat struct { Resource int32 `json:"resource"` Soft int32 `json:"soft"` Hard int32 `json:"hard"` }
func (RlimitStat) String ¶
func (r RlimitStat) String() string
