Babeltrace 2 library
BABELTRACE_EXEC_ON_ABORT=CMDLINE
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.
BABELTRACE_TERM_COLOR=(AUTO | NEVER | ALWAYS)
Force the terminal color support for the babeltrace2(1)
program and the project's plugins.
The available values are:
AUTO
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.
BABELTRACE_TERM_COLOR_BRIGHT_MEANS_BOLD=0
Set to 0 to emit SGR (see
<https://en.wikipedia.org/wiki/ANSI_escape_code>) codes 90 to
97 for bright colors instead of bold (SGR code 1) and
standard color codes (SGR codes 30 to 37).
BABELTRACE_PLUGIN_PATH=PATHS
Set the list of directories, in order, in which dynamic
plugins can be found before other directories are considered
to PATHS (colon-separated, or semicolon on Windows).
LIBBABELTRACE2_DISABLE_PYTHON_PLUGINS=1
Disable the loading of any Babeltrace 2 Python plugin.
LIBBABELTRACE2_INIT_LOG_LEVEL=LVL
Force the Babeltrace 2 library's initial log level to be LVL.
If this environment variable is set, it overrides the log
level set by the --log-level option for the Babeltrace 2
library logger.
The available values for LVL are:
NONE, N
Logging is disabled.
FATAL, F
Severe errors that lead the execution to abort
immediately.
This level should be enabled in production.
ERROR, E
Errors that might still allow the execution to continue.
Usually, once one or more errors are reported at this
level, the application, plugin, or library won't perform
any more useful task, but it should still exit cleanly.
This level should be enabled in production.
WARN, WARNING, W
Unexpected situations which still allow the execution to
continue.
This level should be enabled in production.
INFO, I
Informational messages that highlight progress or
important states of the application, plugins, or library.
This level can be enabled in production.
DEBUG, D
Debugging information, with a higher level of details
than the TRACE level.
This level should NOT be enabled in production.
TRACE, T
Low-level debugging context information.
This level should NOT be enabled in production.
LIBBABELTRACE2_NO_DLCLOSE=1
Make the Babeltrace 2 library leave any dynamically loaded
modules (plugins and plugin providers) open at exit. This can
be useful for debugging purposes.
LIBBABELTRACE2_PLUGIN_PROVIDER_DIR=DIR
Set the directory from which the Babeltrace 2 library
dynamically loads plugin provider shared objects to DIR.
If this environment variable is set, it overrides the default
plugin provider directory.
Babeltrace 2 Python bindings
BABELTRACE_PYTHON_BT2_LOG_LEVEL=LVL
Force the Babeltrace 2 Python bindings log level to be LVL.
If this environment variable is set, it overrides the log
level set by the --log-level option for the Python bindings
logger.
The available values for LVL are:
NONE, N
Logging is disabled.
FATAL, F
Severe errors that lead the execution to abort
immediately.
This level should be enabled in production.
ERROR, E
Errors that might still allow the execution to continue.
Usually, once one or more errors are reported at this
level, the application, plugin, or library won't perform
any more useful task, but it should still exit cleanly.
This level should be enabled in production.
WARN, WARNING, W
Unexpected situations which still allow the execution to
continue.
This level should be enabled in production.
INFO, I
Informational messages that highlight progress or
important states of the application, plugins, or library.
This level can be enabled in production.
DEBUG, D
Debugging information, with a higher level of details
than the TRACE level.
This level should NOT be enabled in production.
TRACE, T
Low-level debugging context information.
This level should NOT be enabled in production.
CLI
BABELTRACE_CLI_LOG_LEVEL=LVL
Force babeltrace2 CLI's log level to be LVL.
If this environment variable is set, it overrides the log
level set by the --log-level option for the CLI logger.
The available values for LVL are:
NONE, N
Logging is disabled.
FATAL, F
Severe errors that lead the execution to abort
immediately.
This level should be enabled in production.
ERROR, E
Errors that might still allow the execution to continue.
Usually, once one or more errors are reported at this
level, the application, plugin, or library won't perform
any more useful task, but it should still exit cleanly.
This level should be enabled in production.
WARN, WARNING, W
Unexpected situations which still allow the execution to
continue.
This level should be enabled in production.
INFO, I
Informational messages that highlight progress or
important states of the application, plugins, or library.
This level can be enabled in production.
DEBUG, D
Debugging information, with a higher level of details
than the TRACE level.
This level should NOT be enabled in production.
TRACE, T
Low-level debugging context information.
This level should NOT be enabled in production.
BABELTRACE_CLI_WARN_COMMAND_NAME_DIRECTORY_CLASH=0
Disable the warning message which babeltrace2-convert(1)
prints when you convert a trace with a relative path that's
also the name of a babeltrace2 command.
BABELTRACE_DEBUG=1
Legacy variable: equivalent to setting the --log-level option
to TRACE.
BABELTRACE_VERBOSE=1
Legacy variable: equivalent to setting the --log-level option
to INFO.
