NAME

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

DESCRIPTION

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).

    Example:

    [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.

    Example:

    {Trace 1, Stream class ID 0, Stream ID 2}
  3. Message type and basic information.

    Examples:

    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 parameters.

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.

INITIALIZATION PARAMETERS

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

Never emit terminal color codes.

always

Always emit terminal color codes.

The BABELTRACE_TERM_COLOR environment variable overrides this parameter.

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 parameter.

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.

ENVIRONMENT VARIABLES

BABELTRACE_TERM_COLOR=(AUTO | NEVER | ALWAYS)
