-
queryCurrentFreq
public long[] queryCurrentFreq()Description copied from class:AbstractCentralProcessor
Get processor current frequency.- Specified by:
queryCurrentFreq
in classAbstractCentralProcessor
- Returns:

in classAbstractCentralProcessor
- Returns:
- The max frequency.
-
queryMaxFreq2
private static long queryMaxFreq2() -
getSystemLoadAverage
public double[] getSystemLoadAverage(int nelem) Description copied from interface:CentralProcessor
Returns the system load average for the number of elements specified, up to 3, representing 1, 5, and 15 minutes. The system load average is the sum of the number of runnable entities queued to the available processors and the number of runnable entities running on the available processors averaged over a period of time.This method is designed to provide a hint about the system load and may be queried frequently.
The way in which the load average is calculated is operating system specific but is typically a damped time-dependent average. Linux includes processes waiting for system resources such as disks, while macOS and Unix consider only processes waiting for CPU.
Windows does not provide a load average. Users may set the configuration property
oshi.os.windows.loadaverage
totrue
to start a daemon thread which will provide a similar metric.The load average may be unavailable on some platforms (e.g., Windows without the above configuration). If the load average is not available, a negative value is returned.
- Parameters:
nelem
- Number of elements to return.- Returns:
- an array of the system load averages for 1, 5, and 15 minutes with the size of the array specified by nelem; or negative values if not available.
-
queryProcessorCpuLoadTicks
public long[][] queryProcessorCpuLoadTicks()Description copied from class:AbstractCentralProcessor
Get the processor CPU load ticks- Specified by:
queryProcessorCpuLoadTicks
in classAbstractCentralProcessor
- Returns:
- The processor CPU load ticks
-
queryProcessorCpuLoadTicks2
private static long[][] queryProcessorCpuLoadTicks2(int processorCount) -
getProcessorID
Fetches the ProcessorID by encoding the stepping, model, family, and feature flags.- Parameters:
stepping
- The steppingmodel
- The modelfamily
- The family- Returns:
- The Processor ID string
-
queryContextSwitches
public long queryContextSwitches()Description copied from class:AbstractCentralProcessor
Get number of context switches- Specified by:
queryContextSwitches
in classAbstractCentralProcessor
- Returns:
- The context switches
-
queryContextSwitches2
private static long queryContextSwitches2() -
queryInterrupts
public long queryInterrupts()Description copied from class:AbstractCentralProcessor
Get number of interrupts- Specified by:
queryInterrupts
in classAbstractCentralProcessor
- Returns:
- The interrupts
-
queryInterrupts2
private static long queryInterrupts2()
