Field Detail

ITERATION_PER_EXECUTION

public static final int ITERATION_PER_EXECUTION

The iteration count which indicates how often the metric generation is repeated per thread execution.

Constant Field Values

MS_COUNT_PER_YEAR

public static final long MS_COUNT_PER_YEAR

The milliseconds per year.

See Also:

Constant Field Values

THREAD_ID_GENERATOR

public static final AtomicInteger THREAD_ID_GENERATOR

Generator to generate the thread id's.

THREAD_ID

public static final ThreadLocal<Integer> THREAD_ID

The thread id which identifies the current thread.

START_TIME

public static final ThreadLocal<Long> START_TIME

The start time on which the thread should begin to generate metrics. Each thread has his own start time, which is calculated with his id and the milliseconds per year. That means each thread generated data in a different year.

INTERVAL

public static final long INTERVAL

The interval length in milliseconds.

See Also:

Constant Field Values

processEngineConfiguration

protected ProcessEngineConfigurationImpl processEngineConfiguration

The process engine configuration, which is used for the metric reporting.
