Description
Interface Summary | |
---|---|
AggregationValue | A value accumulated by an aggregating DTrace action such as count() or sum() . |
Consumer | Interface to the native DTrace library, each instance is a single DTrace consumer. |
ConsumerListener | Listener for data generated by a single DTrace Consumer . |
ExceptionHandler | User-defined application behavior after an exception terminates a running DTrace consumer. |
Record | A data record generated by DTrace. |
StackValueRecord | A value generated by the DTrace stack() , ustack() , or
jstack() action. |
SymbolValueRecord | A value generated by the DTrace mod() , func() , sym() , umod() , ufunc() or usym() action used
to lookup the symbol associated with an address in probe context. |
ValueRecord | A data record generated by DTrace that contains a single value. |
Class Summary | |
---|---|
Aggregate | A consistent snapshot of all aggregations requested by a single
Consumer . |
Aggregation | A snapshot of a DTrace aggregation. |
AggregationRecord | A single key-value pair in a DTrace aggregation. |

ConsumerAdapter | An abstract adapter class for getting events from a Consumer . |
ConsumerEvent | An event indicating a state change in a DTrace Consumer . |
CountValue | A long value aggregated by the DTrace count() action. |
DataEvent | An event used to pass probe data generated by a DTrace Consumer to interested listeners. |
Distribution | A frequency distribution aggregated by the DTrace quantize()
or lquantize() action. |
Distribution.Bucket | A range inclusive at both endpoints and a count of aggregated values that fall in that range. |
Drop | Detail about one or more records dropped by DTrace (not reported to
ConsumerListener.dataReceived() ) due to inadequte buffer space. |
DropEvent | Notification that DTrace has dropped data due to inadequate buffer space. |
Error | An error encountered in the native DTrace library while tracing probe data. |
ErrorEvent | Notification that DTrace has encountered an error. |
ExitRecord | A record indicating that the DTrace exit() action is about to
stop the source Consumer . |
Flow | Description of control flow across function boundaries including direction (entry or return) and depth in the call stack. |
InterfaceAttributes | Triplet of attributes consisting of two stability levels and a dependency class. |
KernelStackRecord | A value generated by the DTrace stack() action. |

sym() action used to lookup the symbol associated with a
kernel address. |
LinearDistribution | A linear frequency distribution aggregated by the DTrace lquantize() action. |
LocalConsumer | Interface to the native DTrace library, each instance is a single DTrace consumer. |
LogDistribution | A power-of-two logarithmic frequency distribution aggregated by the
DTrace quantize() action. |

ProbeDescription | A DTrace probe description consists of provider, module, function, and name. |
ProbeInfo | Probe stability information. |
ProcessEvent | Notification that the state of a target process designated by Consumer.createProcess(String command) or Consumer.grabProcess(int pid) has changed. |
ProcessState | State of a target process designated by Consumer.createProcess(String command) or Consumer.grabProcess(int pid) . |
Program | Identifies a compiled D program. |
Program.File | Identifies a compiled D program, specifically one that has been compiled from a file. |
ProgramInfo | Information about a Program including stability and matching
probe count. |
ScalarRecord | A traced D primitive generated by a DTrace action such as trace() or tracemem() , or else an element in a composite
value generated by DTrace. |
StackFrame | A single stack frame in a StackValueRecord . |
StddevValue | A long value aggregated by the DTrace stddev() action. |
SumValue | A long value aggregated by the DTrace sum() action. |
Tuple | Multi-element key to a value in an Aggregation . |
UserStackRecord | A value generated by the DTrace ustack() or jstack()
action. |
