java.lang.Object
  com.yourkit.api.ProfilingModes

public class ProfilingModes
extends java.lang.Object

Defines constants to be passed to methods of Controller.

Field Summary

static long	ALLOCATION_RECORDING_ADAPTIVE Adaptively skip tracking of some object allocations, keeping overhead at some moderative level.
static long	ALLOCATION_RECORDING_ALL Record each object allocation.
static long	CPU_J2EE Profile J2EE.
static long	CPU_SAMPLING Records CPU times only.
static long	CPU_TRACING Records CPU times and method invocation counts.
static long	MONITOR_PROFILING Use to check if monitor profiling is running
static long	SNAPSHOT_HPROF Pass as parameter of Controller.captureSnapshot(long) to capture snapshot in HPROF format (it will including the heap dump only).
static long	SNAPSHOT_WITH_HEAP Pass as parameter of Controller.captureSnapshot(long) to capture snapshot with all the recorded information, including the heap dump.
static long	SNAPSHOT_WITHOUT_HEAP Pass as parameter of Controller.captureSnapshot(long) to capture snapshot with all the recorded information, but without the heap dump.

Field Detail

ALLOCATION_RECORDING_ALL

public static final long ALLOCATION_RECORDING_ALL

Record each object allocation. May add significant overhead; in most cases, ALLOCATION_RECORDING_ADAPTIVE is a better choice.

See Also:

Controller.startAllocationRecording(long)

ALLOCATION_RECORDING_ADAPTIVE

public static final long ALLOCATION_RECORDING_ADAPTIVE

Adaptively skip tracking of some object allocations, keeping overhead at some moderative level. Best choice for excessive garbage allocation profiling.

See Also:

Controller.startAllocationRecording(long)

CPU_SAMPLING

public static final long CPU_SAMPLING

Records CPU times only. This CPU profiling method has smallest overhead.

CPU_TRACING

public static final long CPU_TRACING

Records CPU times and method invocation counts. Overhead in general is bigger than of CPU_SAMPLING and depends on applied filters. Supported only if profiled application runs with Java 5 or newer.

See Also:

Controller.startCPUProfiling(long, String)

MONITOR_PROFILING

public static final long MONITOR_PROFILING

Use to check if monitor profiling is running

See Also:

Controller.getStatus()

CPU_J2EE

public static final long CPU_J2EE

Profile J2EE. Use in combination with other CPU profiling modes:
CPU_SAMPLING | CPU_J2EE or
CPU_TRACING | CPU_J2EE

See Also:

Controller.startCPUProfiling(long, String)

SNAPSHOT_WITHOUT_HEAP

public static final long SNAPSHOT_WITHOUT_HEAP

Pass as parameter of Controller.captureSnapshot(long) to capture snapshot with all the recorded information, but without the heap dump.

See Also:

Constant Field Values

SNAPSHOT_WITH_HEAP

public static final long SNAPSHOT_WITH_HEAP

Pass as parameter of Controller.captureSnapshot(long) to capture snapshot with all the recorded information, including the heap dump.

SNAPSHOT_HPROF

public static final long SNAPSHOT_HPROF

Pass as parameter of Controller.captureSnapshot(long) to capture snapshot in HPROF format (it will including the heap dump only).
