Subclass should override this function. Args: columns: A list of require columns, e.g., ['pid', 'pss']. pid: If not None, returns only the information of the process with the pid.` IsApplicationRunning(self, application) LaunchApplication(self, application, parameters=None, elevate_privilege=False) RunCommand(self, args) Methods inherited from telemetry.internal.platform.desktop_platform_backend.DesktopPlatformBackend: FlushSystemCacheForDirectory(self, directory) GetDeviceTypeName(self) Methods inherited from telemetry.internal.platform.linux_based_platform_backend.LinuxBasedPlatformBackend: GetClockTicks(*args, **kwargs) `Returns the number of clock ticks per second. The proper way is to call os.sysconf('SC_CLK_TCK') but that is not easy to do on Android/CrOS. In practice, nearly all Linux machines have a USER_HZ of 100, so just return that.` GetCpuStats(self, pid) GetCpuTimestamp(self) GetMemoryStats(self, pid) GetSystemCommitCharge(self) `# Get the commit charge in kB.` GetSystemTotalPhysicalMemory(*args, **kwargs) Static methods inherited from telemetry.internal.platform.linux_based_platform_backend.LinuxBasedPlatformBackend: ParseCStateSample(sample) `Parse a single c-state residency sample. Args: sample: A sample of c-state residency times to be parsed. Organized as a dictionary mapping CPU name to a string containing all c-state names, the times in each state, the latency of each state, and the time at which the sample was taken all separated by newlines. Ex: {'cpu0': 'C0 C1 5000 2000 20 30 1406673171'} Returns: Dictionary associating a c-state with a time.` Methods inherited from telemetry.internal.platform.platform_backend.PlatformBackend: CanCaptureVideo(self) CanMonitorNetworkData(self) CanMonitorThermalThrottling(self) CanTakeScreenshot(self) CooperativelyShutdown(self, proc, app_name) `Cooperatively shut down the given process from subprocess.Popen. Currently this is only implemented on Windows. See crbug.com/424024 for background on why it was added. Args: proc: a process object returned from subprocess.Popen. app_name: on Windows, is the prefix of the application's window class name that should be searched for. This helps ensure that only the application's windows are closed. Returns True if it is believed the attempt succeeded.` DidCreateBrowser(self, browser, browser_backend) DidStartBrowser(self, browser, browser_backend) FlushDnsCache(self) GetNetworkData(self, browser) GetRemotePort(self, port) InitPlatformBackend(self) IsCooperativeShutdownSupported(self) `Indicates whether CooperativelyShutdown, below, is supported.
