* <p>
|

* The DTrace-specific annotations modify the attributes of a DTrace provider
|

* implementation when it is used by the tracing subsystem. The annotations are
|
||||
* added to a {@code com.sun.tracing} provider specification to control
|
||||

|

* <p>
|
||||
* Any other tracing subsystems supported by the system will ignore these
|
||||
* annotations.
|
||||
* <p>
|
||||
* DTrace probes have additional fields and stability attributes that are
|
||||
* not accounted for in the generic tracing package. If unspecified, the
|
||||
* default values are used for the stability and dependency attributes of
|
||||
* probes, as well as for the module and field names of the generated probes.
|
||||
* The values can be specified by adding the appropriate annotations to the
|
||||
* provider specification.
|
||||
* <p>
|
||||
* The {@code FunctionName} annotation is used to annotate the tracepoint
|
||||
* methods defined in the provider specification. The value of this annotation
|
||||
* is used as the {@code function} field in the generated DTrace probes. It
|
||||
* is typically set to the name of the enclosing function where the
|
||||
* tracepoint is triggered.
|
||||
* <p>
|
||||
* The {@code ModuleName} annotation is used to annotate the provider
|
||||
* specification itself and applies to all the probes in the provider. It
|
||||
* sets the value of the {@code module} field in the generated DTrace probes.
|
||||
* <p>
|
||||
* The remaining annotations, are also applied to the provider itself, and
|
||||
* are used to set the stability and dependency attributes of all probes in
|
||||
* that provider. Each probe field and the probe arguments can be
|
||||
* independently assigned interface attributes to control the stability
|
||||
* ratings of the probes.
|

/**
|
||||
* This package provides a mechanism for defining and
|
||||
* inserting tracepoints into Java-technology based applications, which
|
||||
* can then be monitored by the tracing tools available on the system.
|
||||
* <p>
|
||||
* To add tracepoints to a program, you must first decide where to place the
|
||||
* tracepoints, what the logical names are for these points, what information
|
||||
* will be available to the tracing mechanisms at each point, and decide upon
|
||||
* any logical grouping.
|
||||
* <p>
|
||||
* You add instrumentation to a program in three steps:
|
||||
* <ul>
|
||||
* <li>First, declare tracepoints by creating interfaces to define
|
||||
* them, and include these interfaces in the program definition.
|
||||
* The declared interfaces are standard Java technology-based
|
||||
* interfaces and are compiled with the program.</li>
|
||||
* <li>Second, add code in the application to create an instance of the
|
||||
* interface at some point during the initialization of the application,
|
||||
* using a factory class provided by the system. The reference to the
|
||||
* instance can be stored as a global static, or passed as context to all
|
||||
* the places where it is needed.</li>
|
||||
* <li>Finally, add the actual tracepoints to the desired locations in the
|
||||
* application by inserting a call to one of the methods defined in the
|
||||
* interface, via the factory-created reference.</li>
|
||||
* </ul>
|
||||
* <p>
|
||||
* The method calls representing the tracepoints have no logical
|
||||
* impact on the program. The side effect of the call is that any
|
||||
* activated tracing mechanisms will be notified that the tracepoint has
|
||||
* been hit, and will take whatever actions are appropriate (for example,
|
||||
* logging the tracepoint, or triggering a DTrace probe, etc.). In most
|
||||
* cases, the impact on performance of adding tracepoints to the application
|
||||
* will be minimal.
|
||||
* <p>
|
||||
* Each logical grouping of tracepoints should be defined in a common
|
||||
* interface, called a <i>provider</i>. An application can have one or many
|
||||
* providers. Each provider is independent and can be created whenever
|
||||
* it is appropriate for that provider, for example, when a subsytem is
|
||||
* initialized. Providers should be disposed of when they are no longer
|
||||
* needed, to free up any associated system resources. Each tracepoint
|
||||
* in a provider is represented by a method in that interface. These methods
|
||||
* are referred to as <i>probes</i>. The method signature determines the probe
|
||||
* parameters. A call to the method with the specified parameters triggers
|
||||
* the probe and makes its parameter values visible to any associated tracing
|
||||
* mechanism.
|
||||
* <p>
|
||||
* User-defined interfaces which represent providers must extend the
|
||||
* {@code Provider} interface. To activate the system-defined
|
||||
* tracing mechanisms, you must obtain an instance of the
|
||||
* {@code ProviderFactory} class, and pass the class of the provider to
|
||||
* the {@code createProvider()} method. The returned instance is then used to
|
||||
* trigger the probes later in the application.
|
||||
* <p>
|
||||
* In addition to triggering the probes, the provider instance can be used
|
||||
* to obtain direct references to the {@code Probe} objects, which can be used
|
||||
* directly for triggering, or can be queried to determine whether the probe is
|
||||
* currently being traced. The {@code Provider} interface also defines a
|
||||
* {@code Provider.dispose()} method which is used to free up any resources
|
||||
* that might be associated with that provider.
|
||||
* <p>
|
||||
* When a probe is triggered, any activated tracing system will be given
|
||||
* the provider name, the probe name, and the values of the probe arguments.
|
||||
* The tracing system is free to consume this data is whatever way is
|
||||
* appropriate.
|
||||
* By default, the provider name is the same as the class name of the interface
|
||||
* that defines the provider. Similarly, the probe name is
|
||||
* the name of the method that defines the probe. These default values
|
||||
* can be over-ridden by annotations. The provider definition can be
|
||||
* annotated with the {@code @ProviderName} annotation, whose value will
|
||||
* indicate the provider name that the tracing system will use. Similarly,
|
||||
* the {@code @ProbeName} annotation annotates a declared method and
|
||||
* indicates the probe name that should be used in the place of the
|
||||
* method name. These annotations can be used to define providers and
|
||||
* probes with the same name, in cases where the semantics of the Java language
|
||||
* may prevent this.
|
||||
* <p>
|
||||
* Here is a very small and simple usage example:
|
||||
* <p>
|
||||
*
|
||||
<PRE>
|
||||
import com.sun.tracing.Provider;
|
||||
import com.sun.tracing.ProviderFactory;
|
||||
|
||||
interface MyProvider extends Provider {
|
||||
void startProbe();
|
||||
void finishProbe(int value);
|
||||
}
|
||||
|
||||
public class MyApplication {
|
||||
public static void main(String argv[]) {
|
||||
ProviderFactory factory = ProviderFactory.getDefaultFactory();
|
||||
MyProvider trace = factory.createProvider(MyProvider.class);
|
||||
|
||||
trace.startProbe();
|
||||
int result = foo();
|
||||
trace.finishProbe(result);
|
||||
|
||||
trace.dispose();
|
||||
}
|
||||
}
|
||||
</PRE>
|
||||
* <p>
|
||||
* The Java Development Kit (JDK) currently only includes one system-defined
|
||||
* tracing framework: DTrace. DTrace is enabled automatically whenever an
|
||||
* application is run on a system and a JDK release that supports it. When
|
||||
* DTrace is enabled, probes are made available for listing and matching by
|
||||
* DTrace scripts as soon as the provider is created. At the tracepoint, an
|
||||
* associated DTrace script is informed of the creation of the provider, and
|
||||
* it takes whatever action it is designed to take. Tracepoints in the
|
||||
* program have the following DTrace probe names:<br>
|
||||
* {@code <provider><pid>:<module>:<function>:<probe>}
|
||||
* Where:
|
||||
* <ul>
|
||||
* <li>{@code <provider>} the provider name as specified by the application</li>
|
||||
* <li>{@code <pid>} the operating system process ID</li>
|
||||
* <li>{@code <module>} undefined, unless specified by the application</li>
|
||||
* <li>{@code <function>} undefined, unless specified by the application</li>
|
||||
* <li>{@code <probe>} the probe name as specified by the application</li>
|
||||
* </ul>
|
||||
* <p>
|
||||
* The {@code com.sun.tracing.dtrace} package contains additional
|
||||
* annotations that can be used to control the names used for the
|
||||
* <code>module</code> and <code>function</code> fields, as well as annotations
|
||||
* that can be added to the provider to control probe stability and dependency
|
||||
* attributes.
|
||||
* <p>
|
||||
* Integer, float and string probe parameters are made available to DTrace
|
||||
* using
|
||||
* the built-in argument variables, {@code arg0 ... arg_n}. Integer-types
|
||||
* are passed by value (boxed values are unboxed), floating-point types are
|
||||
* passed as encoded integer
|
||||
* arguments, and {@code java.lang.String} objects are converted
|
||||
* to UTF8 strings, so they can be read into the DTrace script using the
|
||||
* {@code copyinstr()} intrinsic. Non-string and non-boxed primitive
|
||||
* reference arguments are only
|
||||
* placeholders and have no value.
|
||||
* <p>
|
||||
* Using the example above, with a theoretical process ID of 123, these are
|
||||
* the probes that can be traced from DTrace:
|
||||
<PRE>
|
||||
MyProvider123:::startProbe
|
||||
MyProvider123:::finishProbe
|
||||
</PRE>
|
||||
* When {@code finishProbe} executes, {@code arg0} will contain the
|
||||
* value of {@code result}.
|
||||
* <p>
|
||||
* The DTrace tracing mechanism is enabled for all providers, apart from in the
|
||||
* following circumstances:
|
||||
* <ul>
|
||||
* <li>DTrace is not supported on the underlying system.</li>
|
||||
* <li>The property {@code com.sun.tracing.dtrace} is set to "disable".</li>
|
||||
* <li>The RuntimePermission {@code com.sun.tracing.dtrace.createProvider}
|
||||
* is denied to the process.</li>

* This package contains internal common code for implementing tracing

* frameworks, and defined a number of existing frameworks.
|

* <p>
|
||||
* There are four tracing frameworks currently defined. The "Null" and
|
||||
* "Multiplex" frameworks are used internally as part of the implementation.
|
||||
* The "DTrace" framework is the prime consumer framework at the moment,
|
||||
* while the "PrintStream" framework is a functional, but hidden, framework
|
||||
* which can be used to track probe firings. All but the "DTrace" framework
|
||||
* are defined in this package. The "DTrace" framework is implemented in the
|
||||
* {@code sun.tracing.dtrace} package.
|
||||
* <p>
|
||||
* This package also contains the {@code ProviderSkeleton} class, which
|
||||
* holds most of the common code needed for implementing frameworks.
|
||||
* <p>
|
||||
* The "Null" framework is used when there are no other active frameworks.
|
||||
* It accomplishes absolutely nothing and is merely a placeholder so that
|
||||
* the application can call the tracing routines without error.
|
||||
* <p>
|
||||
* The "Multiplex" framework is used when there are multiple active frameworks.
|
||||
* It is initialized with the framework factories and create providers and
|
||||
* probes that dispatch to each active framework in turn.
|
||||
* <p>
|
||||
* The "PrintStream" framework is currently a debugging framework which
|
||||
* dispatches trace calls to a user-defined PrintStream class, defined by
|
||||
* a property. It may some day be opened up to general use.
|
||||
* <p>
|
||||
* See the {@code sun.tracing.dtrace} and {@code com.sun.tracing.dtrace}
|
||||
* packages for information on the "DTrace" framework.
