Method Detail

create

public static OperatingSystemInfo create()

getName

public String getName()

Retrieves the name of the operating system. For Linux, this method simply returns "Linux"; method getDistributionName() can then be utilized to retrieve the distribution name and version.

Returns:

the name of the operating system.

See Also:

OperatingSystemMXBean.getName()

getVersion

public String getVersion()

Retrieves the version of the operating system. For Linux, kernel version is returned.

Returns:

the version of the operating system.

See Also:

OperatingSystemMXBean.getVersion()

getDistributionName

public String getDistributionName()

Retrieves the name of the operating system distribution. Currently, this method only supports Linux distributions. For instance, for a Debian 8, it may return "Debian GNU/Linux 8 (jessie)".

Returns:

the name of the operating system distribution.

getArchitecture

public String getArchitecture()

Retrieves the operating system architecture.

Returns:

the operating system architecture.

See Also:

OperatingSystemMXBean.getArch()

getNumberOfLogicalProcessors

public int getNumberOfLogicalProcessors()

Retrieves the number of logical processors. Logical processors are individual cores, summed up for all sockets and, possibly, multiplied by a factor of two whenever Intel's hyper-threading technology is in play.

Returns:

the number of logical processors.

See Also:

OperatingSystemMXBean.getAvailableProcessors()

getPhysicalMemorySizeInBytes

public long getPhysicalMemorySizeInBytes()

Retrieves the physical memory (RAM) size in bytes.

Returns:

the physical memory (RAM) size in bytes.

See Also:

OperatingSystemMXBean.getTotalPhysicalMemorySize()

getSwapSpaceSizeInBytes

public long getSwapSpaceSizeInBytes()

Retrieves the swap space size in bytes.

Returns:

the swap space size in bytes.

See Also:

OperatingSystemMXBean.getTotalSwapSpaceSize()

getDiskSpaceInBytesByRootPaths

public Map<String,Long> getDiskSpaceInBytesByRootPaths()

Retrieves the total disk space in bytes by root paths.

Returns:

a map of total disk space in bytes by root paths.
