[lttng-dev] [PATCH lttng-tools v3 1/6] Rename the "metadata regenerate" command to "regenerate metadata"
Julien Desfossez
jdesfossez at efficios.com
Tue Jul 5 14:54:33 UTC 2016
Prepare the deprecation of the "metadata regenerate" command since we
need to regenerate the statedump as well, so it is more convenient to
have one command to regenerate various session's attributes.

DESCRIPTION
-----------
-The `lttng metadata` command manages a tracing session's metadata
-generation options.
-
-As of this version, only the `regenerate` command's action is available.
-Regenerating a tracing session's metadata can be used to

-
-This command is meant to be used to resample the wall-clock time
-following a major

-correction. As such, a system booting with an incorrect wall time can be
-traced before its wall time is NTP-corrected. Regenerating the tracing
-session's metadata ensures that trace viewers can accurately determine
-the events time relative to Unix Epoch.
+WARNING: This command is **deprecated**; it has been replaced by the *lttng
+regenerate metadata* command (see man:lttng-regenerate(1)).

+DESCRIPTION
+-----------
+The `lttng regenerate` command manages a tracing session's data regeneration
+options.
+
+As of this version, only the `metadata` command's action is available.
+Regenerating a tracing session's metadata can be used to
+resample the offset between the system's monotonic clock and
+the wall-clock time.
+
+This command is meant to be used to resample the wall-clock time
+following a major

+ Manage the metadata generation of the tracing session named 'SESSION'

+
+
+LIMITATIONS
+-----------
+The `lttng regenerate metadata` command can only be used on kernel and
+user space tracing sessions (using per-user buffering), in non-live
+mode.
+
+See man:lttng-enable-channel(1) for more information about
+buffering schemes and man:lttng-create(1) for more information
+about the different tracing session modes.
