General options are described in lttng(1).
-s SESSION, --session=SESSION
Manage the metadata generation of the tracing session named
SESSION instead of the current tracing session.
Program information-h, --help
Show command help.
This option, like lttng-help(1), attempts to launch /usr/bin/man
to view the command’s man page. The path to the man pager can be
overridden by the LTTNG_MAN_BIN_PATH environment variable.
List available command options.
The lttng metadata regenerate command can only be used on kernel and
user space tracing sessions (using per-user buffering), in non-live
See lttng-enable-channel(1) for more information about buffering
schemes and lttng-create(1) for more information about the different
tracing session modes.
Set to 1 to abort the process after the first error is
Overrides the $HOME environment variable. Useful when the user
running the commands has a non-writable home directory.

may be found.
Full session daemon binary path.
The --sessiond-path option has precedence over this environment
Note that the lttng-create(1) command can spawn an LTTng session
daemon automatically if none is running. See lttng-sessiond(8) for
the environment variables influencing the execution of the session
User LTTng runtime configuration.
This is where the per-user current tracing session is stored

information about tracing sessions.
Default output directory of LTTng traces. This can be overridden
with the --output option of the lttng-create(1) command.
User LTTng runtime and configuration directory.
Default location of saved user tracing sessions (see
lttng-save(1) and lttng-load(1)).
System-wide location of saved tracing sessions (see lttng-save(1)
Note$LTTNG_HOME defaults to $HOME when not explicitly set.

Also thanks to the Ericsson teams working on tracing which helped us
greatly with detailed bug reports and unusual test cases.
