NAME         top

       babeltrace2-sink.text.details - Babeltrace 2's detailed plain text
       sink component class

DESCRIPTION         top

       A Babeltrace 2 sink.text.details component deterministically prints
       the messages it consumes, with all the possible details, to the
       standard output.

                       | sink.text.details |
                       |                   +--> Detailed messages to the
           Messages -->@ in                |    standard output

       See babeltrace2-intro(7) to learn more about the Babeltrace 2 project
       and its core concepts.

       The purpose of a sink.text.details component is to always print the
       same text for the same sequence of consumed messages, whatever the
       build configuration of the Babeltrace 2 project. This can be helpful
       for testing, debugging, and support.

       The output format is optimized for human reading, with colors when
       the terminal supports it. You can control how the component prints
       color codes with the color parameter.

       To achieve a reproducible output, a sink.text.details component sorts
       the members of all unordered sets before it prints them. For example,
       the component sorts enumeration field class mappings by label and,
       for each mapping, sorts the contained ranges.

       In normal mode, each message has at least three lines, the three
       first being:

        1. Timing information (cycles and nanoseconds since origin).


               [102,423,274,041,829 cycles, 1,441,852,841,550,867,846 ns from origin]

        2. Unique stream identifier.

           To be able to follow a specific trace object (the name and UUID
           properties of a trace object are optional), the component assigns
           a unique numeric ID to the trace object when it first encounters
           it in a stream beginning message.


               {Trace 1, Stream class ID 0, Stream ID 2}

        3. Message type and basic information.


               Packet beginning:

               Event `lttng_ust_statedump:build_id` (Class ID 2):

       What follows depend on the specific message type. The component
       prints all the available properties and fields in a human-readable,
       structured format.

       When a sink.text.details component consumes a stream beginning or an
       event message, it can print a metadata block for all the metadata
       objects which it did not print yet. You can use the with-metadata
       parameter to disable this.

       You can hide specific properties with the with-stream-class-name,
       with-stream-name, with-time, with-trace-name, and with-uuid

       To make the component hide many message details and print a single
       message per line, you can enable the compact mode with the compact


       color=(never | auto | always) [optional string]
           Force the terminal color support, one of:

           auto (default)
               Only emit terminal color codes when the standard output and
               error streams are connected to a color-capable terminal.

               Never emit terminal color codes.

               Always emit terminal color codes.

           The BABELTRACE_TERM_COLOR environment variable overrides this

       compact=yes [optional boolean]
           Enable compact mode.

           In compact mode, the component prints one line per message,
           omitting many details about messages. This is useful if you only
           need the time, type, and very basic information of messages.

           In compact mode, the component still prints the full metadata
           blocks. You can remove such blocks with the with-metadata

       with-metadata=no [optional boolean]
           Do not print metadata blocks.

       with-stream-class-name=no [optional boolean]
           Do not print stream class names.

       with-stream-name=no [optional boolean]
           Do not print stream names.

       with-time=no [optional boolean]
           Do not print timing information.

       with-trace-name=no [optional boolean]
           Do not print trace names.

       with-uuid=no [optional boolean]
           Do not print UUIDs.

           Single input port.


           Execute the command line CMDLINE, as parsed like a UNIX 98 shell,
           when any part of the Babeltrace 2 project unexpectedly aborts.

           The application only aborts when the executed command returns,
           ignoring its exit status.

           This environment variable is ignored when the application has the
           setuid or the setgid access right flag set.

           Force the terminal color support for the babeltrace2(1) program
           and the project’s plugins.

           The available values are:

               Only emit terminal color codes when the standard output and
               error streams are connected to a color-capable terminal.

               Never emit terminal color codes.

               Always emit terminal color codes.

           Set to 0 to emit SGR (see
           <>) codes 90 to 97
           for bright colors instead of bold (SGR code 1) and standard color
           codes (SGR codes 30 to 37).
