ENVIRONMENT VARIABLES

48   Babeltrace 2 library
49       BABELTRACE_EXEC_ON_ABORT=CMDLINE
50           Execute the command line CMDLINE, as parsed like a UNIX 98 shell,
51           when any part of the Babeltrace 2 project unexpectedly aborts.
52
53           The application only aborts when the executed command returns,
54           ignoring its exit status.
55
56           This environment variable is ignored when the application has the
57           setuid or the setgid access right flag set.
58
59       BABELTRACE_TERM_COLOR=(AUTO | NEVER | ALWAYS)
60           Force the terminal color support for the babeltrace2(1) program and
61           the project’s plugins.
62
63           The available values are:
64
65           AUTO
66               Only emit terminal color codes when the standard output and
67               error streams are connected to a color-capable terminal.
68
69           NEVER
70               Never emit terminal color codes.
71
72           ALWAYS
73               Always emit terminal color codes.
74
75       BABELTRACE_TERM_COLOR_BRIGHT_MEANS_BOLD=0
76           Set to 0 to emit SGR (see
77           <https://en.wikipedia.org/wiki/ANSI_escape_code>) codes 90 to 97
78           for bright colors instead of bold (SGR code 1) and standard color
79           codes (SGR codes 30 to 37).
80
81       BABELTRACE_PLUGIN_PATH=PATHS
82           Set the list of directories, in order, in which dynamic plugins can
83           be found before other directories are considered to PATHS
84           (colon-separated, or semicolon on Windows).
85
86       LIBBABELTRACE2_DISABLE_PYTHON_PLUGINS=1
87           Disable the loading of any Babeltrace 2 Python plugin.
88
89       LIBBABELTRACE2_INIT_LOG_LEVEL=LVL
90           Force the Babeltrace 2 library’s initial log level to be LVL.
91
92           If this environment variable is set, it overrides the log level set
93           by the --log-level option for the Babeltrace 2 library logger.
94
95           The available values for LVL are:
96
97           NONE, N
98               Logging is disabled.
99
100           FATAL, F
101               Severe errors that lead the execution to abort immediately.
102
103               This level should be enabled in production.
104
105           ERROR, E
106               Errors that might still allow the execution to continue.
107
108               Usually, once one or more errors are reported at this level,
109               the application, plugin, or library won’t perform any more
110               useful task, but it should still exit cleanly.
111
112               This level should be enabled in production.
113
114           WARN, WARNING, W
115               Unexpected situations which still allow the execution to
116               continue.
117
118               This level should be enabled in production.
119
120           INFO, I
121               Informational messages that highlight progress or important
122               states of the application, plugins, or library.
123
124               This level can be enabled in production.
125
126           DEBUG, D
127               Debugging information, with a higher level of details than the
128               TRACE level.
129
130               This level should NOT be enabled in production.
131
132           TRACE, T
133               Low-level debugging context information.
134
135               This level should NOT be enabled in production.
136
137       LIBBABELTRACE2_NO_DLCLOSE=1
138           Make the Babeltrace 2 library leave any dynamically loaded modules
139           (plugins and plugin providers) open at exit. This can be useful for
140           debugging purposes.
141
142       LIBBABELTRACE2_PLUGIN_PROVIDER_DIR=DIR
143           Set the directory from which the Babeltrace 2 library dynamically
144           loads plugin provider shared objects to DIR.
145
146           If this environment variable is set, it overrides the default
147           plugin provider directory.
148
149   Babeltrace 2 Python bindings
150       BABELTRACE_PYTHON_BT2_LOG_LEVEL=LVL
151           Force the Babeltrace 2 Python bindings log level to be LVL.
152
153           If this environment variable is set, it overrides the log level set
154           by the --log-level option for the Python bindings logger.
155
156           The available values for LVL are:
157
158           NONE, N
159               Logging is disabled.
160
161           FATAL, F
162               Severe errors that lead the execution to abort immediately.

165
166           ERROR, E
167               Errors that might still allow the execution to continue.
168
169               Usually, once one or more errors are reported at this level,
170               the application, plugin, or library won’t perform any more
171               useful task, but it should still exit cleanly.
172
173               This level should be enabled in production.
174
175           WARN, WARNING, W

177               continue.

180
181           INFO, I
182               Informational messages that highlight progress or important
183               states of the application, plugins, or library.
184
185               This level can be enabled in production.
186
187           DEBUG, D
188               Debugging information, with a higher level of details than the

199       BABELTRACE_CLI_LOG_LEVEL=LVL
200           Force babeltrace2 CLI’s log level to be LVL.

203           by the --log-level option for the CLI logger.
204
205           The available values for LVL are:

219               the application, plugin, or library won’t perform any more
220               useful task, but it should still exit cleanly.

248           Disable the warning message which babeltrace2-convert(1) prints

251
252       BABELTRACE_DEBUG=1
