                             long profilingTimestamp)

Constructs a new instance summary profiling event.

Parameters:

profilingInterval - the interval of time this profiling event covers in milliseconds

ioWaitCPU - the percentage of time the CPU(s) spent in state IOWAIT during the profiling interval

idleCPU - the percentage of time the CPU(s) spent in state IDLE during the profiling interval

userCPU - the percentage of time the CPU(s) spent in state USER during the profiling interval

systemCPU - the percentage of time the CPU(s) spent in state SYSTEM during the profiling interval

hardIrqCPU - the percentage of time the CPU(s) spent in state HARD_IRQ during the profiling interval

softIrqCPU - the percentage of time the CPU(s) spent in state SOFT_IRQ during the profiling interval

totalMemory - the total amount of this instance's main memory in bytes

freeMemory - the free amount of this instance's main memory in bytes

bufferedMemory - the amount of main memory the instance uses for file buffers

cachedMemory - the amount of main memory the instance uses as cache memory

cachedSwapMemory - The amount of main memory the instance uses for cached swaps

receivedBytes - the number of bytes received via network during the profiling interval

transmittedBytes - the number of bytes transmitted via network during the profiling interval

jobID - the ID of this job this profiling event belongs to

timestamp - the time stamp of this profiling event's creation

profilingTimestamp - the time stamp relative to the beginning of the job's execution
