Constructor Detail

AggregateProcessInfo

public AggregateProcessInfo(long pid)

Creates an aggregate process info object that will aggregate data related to the process with the given pid and all its child processes.

Parameters:

pid - the parent pid whose data, along with its children process data, will be aggregated

Method Detail

refresh

public void refresh()
             throws SystemInfoException

Description copied from class: ProcessInfo

Takes a fresh snapshot of non static properties of the underlying process. This method internally serializes calls so that it maintains a consistent view of the various Sigar call results.

Overrides:

refresh in class ProcessInfo

Throws:

SystemInfoException

getAggregateTime

public AggregateProcessInfo.AggregateProcTime getAggregateTime()

getAggregateMemory

public AggregateProcessInfo.AggregateProcMem getAggregateMemory()

getAggregateCpu

public AggregateProcessInfo.AggregateProcCpu getAggregateCpu()

getAggregateFileDescriptor

public AggregateProcessInfo.AggregateProcFd getAggregateFileDescriptor()

toString

public String toString()

Overrides:

toString in class ProcessInfo
