Profiler

Profiling class for updated information on process status

class DIRAC.Core.Utilities.Profiler.Profiler(pid=None)

Bases: object

Class for profiling both general stats about a machine and individual processes. Every instance of this class is associated to a single process by using its PID. Calls to the different methods of the class will return the current state of the process.

__init__(pid=None)

Parameters:: pid (str) – PID of the process to be profiled

cpuPercentage(**kwargs)

cpuUsageSystem(**kwargs)

cpuUsageUser(**kwargs)

getAllProcessData(withChildren=False, withTerminatedChildren=False): Returns data available about a process

memoryUsage(**kwargs)

numThreads(**kwargs)

pid(): Returns the process PID

runningTime(**kwargs)

status(**kwargs)

vSizeUsage(**kwargs)

DIRAC.Core.Utilities.Profiler.checkInvocation(func): Decorator for invoking psutil methods
