Returns:

getSystemLoadAverage

double getSystemLoadAverage()

Returns the system load average; or a negative value if not available

Returns:

getUsedMemory

long getUsedMemory()

Returns the amount of used memory in bytes.

Returns:

getCommittedMemory

long getCommittedMemory()

Returns the amount of memory in bytes that is committed for the Java virtual machine to use.

Returns:

getMaxMemory

long getMaxMemory()

Returns the maximum amount of memory in bytes that can be used for memory management.

Returns:

getThreadCount

int getThreadCount()

Returns the current number of live threads including both daemon and non-daemon threads.

Returns:

getDaemonThreadCount

int getDaemonThreadCount()

Returns the current number of live daemon threads.

Returns:

getGcCollectionCount

long getGcCollectionCount()

Returns the total number of collections that have occurred.

Returns:
