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 parameter.


       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

               Never emit terminal color codes.

               Always emit terminal color codes.

           The BABELTRACE_TERM_COLOR environment variable overrides this

       compact=VAL [optional boolean]
           If VAL is true, then 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

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

           Default: false.

       with-metadata=VAL [optional boolean]
           If VAL is false, then do not print metadata blocks.

           Default: true.

       with-stream-class-name=VAL [optional boolean]
           If VAL is false, then do not print stream class names.

           Default: true.

       with-stream-name=VAL [optional boolean]
           If VAL is false, then do not print stream names.

           Default: true.

       with-time=VAL [optional boolean]
           If VAL is false, then do not print timing information.

           Default: true.

       with-trace-name=VAL [optional boolean]
           If VAL is false, then do not print trace names.

           Default: true.

       with-uuid=VAL [optional boolean]
           If VAL is false, then do not print UUIDs.

           Default: true.

           The available values are:

               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).
