pysys.process.monitorimpl¶

Contains implementations of the pysys.process.monitor.BaseProcessMonitor interface.

DEFAULT_PROCESS_MONITOR¶

pysys.process.monitorimpl.DEFAULT_PROCESS_MONITOR = <class 'pysys.process.monitorimpl.UnixProcessMonitor'>¶: Specifies the default BaseProcessMonitor subclass to be used for monitoring OS-level process information on the current platform.

WindowsProcessMonitor¶

class pysys.process.monitorimpl.WindowsProcessMonitor(owner, process, interval, handlers, **pmargs)[source]¶

Bases: pysys.process.monitor.BaseProcessMonitor

Windows implementation of a process monitor.

Uses the GetProcessMemoryInfo, and GetProcessTimes APIs. The UserTime and KernelTime are summed together to calculate the CPU utilization for this process.

_timer_ns()[source]¶: Return a monotonically incrementing clock value in nanoseconds (1000**3) that can be used to calculate performance results.

UnixProcessMonitor¶

class pysys.process.monitorimpl.UnixProcessMonitor(owner, process, interval, handlers, **pmargs)[source]¶

Bases: pysys.process.monitor.BaseProcessMonitor

Unix implementation of a process monitor.

Uses the ps command line tool, reading columns pcpu, rss and vsz.
