Basic collector

The basic collector demonstrates the creation of a subscriber and prints of the data received from various streams. In order to obtain the data from an application instrumented with XPTI, the following steps must be performed.

  1. Set the environment variable that indicates that tracing has been enabled.

    This is defined by the variable XPTI_TRACE_ENABLE. The possible values taken by this environment variable are:

    To enable: XPTI_TRACE_ENABLE=1 or XPTI_TRACE_ENABLE=true

    To disable: XPTI_TRACE_ENABLE=0 or XPTI_TRACE_ENABLE=false

  2. Set the environment variable that points to the XPTI framework dispatcher so the stub library can dynamically load it and dispatch the calls to the dispatcher. XPTI_FRAMEWORK_DISPATCHER=/path/to/libxptifw.[so,dll,dylib]

  3. Set the environment variable that points to the subscriber, which in this case is libbasic_collector.[so,dll,dylib].

    XPTI_SUBSCRIBERS=/path/to/libxpti_basic_collector.[so,dll,dylib]

For more detail on the framework, the tests that are provided and their usage, please consult the XPTI Framework library documentation.
