--list-options Simple listing of options
-o, --output PATH Specify output path for traces
--no-output Traces will not be outputted
--snapshot Set the session in snapshot mode.
Created in no-output mode and uses the URL,
if one, as the default snapshot output.
Every channel will be set in overwrite mode
and with mmap output (splice not supported).
Extended Options:
Using these options, each API call can be controlled individually.
-U, --set-url=URL Set URL destination of the trace data.
It is persistent for the session lifetime.
This will set both data and control URL.
You can change it with the enable-consumer cmd
-C, --ctrl-url=URL Set control path URL. (Must use -D also)
-D, --data-url=URL Set data path URL. (Must use -C also)
Please refer to the man page (lttng(1)) for more information on network
streaming mechanisms and explanation of the control and data port
You must have a running remote lttng-relayd for network streaming
URL format is has followed:
proto://[HOST|IP][:PORT1[:PORT2]][/TRACE_PATH]
Supported protocols are (proto):
> file://...
Local filesystem full path.
> net[6]://...
This will use the default network transport layer which is
TCP for both control (PORT1) and data port (PORT2).
The default ports are respectively 5342 and 5343.
> tcp[6]://...
Can only be used with -C and -D together
NOTE: IPv6 address MUST be enclosed in brackets '[]' (rfc2732)
Examples:
# lttng create -U net://192.168.1.42
Uses TCP and default ports for the given destination.
# lttng create -U net6://[fe80::f66d:4ff:fe53:d220]
Uses TCP, default ports and IPv6.
# lttng create s1 -U net://myhost.com:3229
Set the consumer to the remote HOST on port 3229 for control.

Event options:
--tracepoint Tracepoint event (default)
- userspace tracer supports wildcards at end of string.
Don't forget to quote to deal with bash expansion.
e.g.:
"*"
"app_component:na*"
--probe (addr | symbol | symbol+offset)
Dynamic probe.
Addr and offset can be octal (0NNN...),
decimal (NNN...) or hexadecimal (0xNNN...)
--function (addr | symbol | symbol+offset)
Dynamic function entry/return probe.
--syscall System call event
--loglevel name
Tracepoint loglevel range from 0 to loglevel
--loglevel-only name
Tracepoint loglevel (only this loglevel)
The loglevel or loglevel-only options should be
combined with a tracepoint name or tracepoint
wildcard.
Available loglevels:
(higher value is more verbose)
TRACE_EMERG = 0
TRACE_ALERT = 1
TRACE_CRIT = 2
TRACE_ERR = 3
TRACE_WARNING = 4
TRACE_NOTICE = 5
TRACE_INFO = 6
TRACE_DEBUG_SYSTEM = 7
TRACE_DEBUG_PROGRAM = 8
TRACE_DEBUG_PROCESS = 9
TRACE_DEBUG_MODULE = 10
TRACE_DEBUG_UNIT = 11
TRACE_DEBUG_FUNCTION = 12
TRACE_DEBUG_LINE = 13
TRACE_DEBUG = 14
(shortcuts such as "system" are allowed)
-f, --filter 'expression'
Filter expression on event fields and context.
Event recording depends on evaluation.
Only specify on first activation of
a given event within a session.
Filter only allowed when enabling
events within a session before tracing
is started. If the filter fails to link
with the event within the traced domain,
the event will be discarded. Currently,
filter is only implemented for the user-space
tracer.
Expression examples:.
'intfield > 500 && intfield < 503'
'(strfield == "test" || intfield != 10) && intfield > 33'
'doublefield > 1.1 && intfield < 5.3'
Wildcards are allowed at the end of strings:
'seqfield1 == "te*"'
In string literals, the escape character is '\'.
Use '\*' for the '*' character, and '\\' for
the '\' character. Wildcard match any sequence of,
characters including an empty sub-string (match 0 or
more characters).
Context information can be used for filtering. The
examples below show usage of context filtering on
process name (with a wildcard), process ID range, and
unique thread ID for filtering. The process and
thread ID of running applications can be found under
columns "PID" and "LWP" of the "ps -eLf" command.
'$ctx.procname == "demo*"'
'$ctx.vpid >= 4433 && $ctx.vpid < 4455'
'$ctx.vtid == 1234'

spawn_viewer view_trace usage: lttng view [SESSION_NAME] [OPTIONS]
By default, the babeltrace viewer will be used for text viewing
Where SESSION_NAME is an optional session name. If not specified, lttng will
get it from the configuration file (.lttngrc).
-t, --trace-path PATH Trace directory path for the viewer
-e, --viewer CMD Specify viewer and/or options to use
This will completely override the default viewers so
please make sure to specify the full command. The trace
directory path of the session will be appended at the end
to the arguments
DEBUG1 [%ld/%ld]: Using %s viewer (in %s() at commands/view.c:258)

usage: lttng snapshot [OPTION] ACTION
Actions:
add-output [-m ] [-s ] [-n ] | -C -D
Setup and add an snapshot output for a session.
del-output ID | NAME [-s ]
Delete an output for a session using the ID.
list-output [-s ]
List the output of a session.
record [-m ] [-s ] [-n ] [ | -C -D ]
Snapshot a session's buffer(s) for all domains. If an URL is
specified, it is used instead of a previously added output.
Specifying only a name or/a size will override the current output value.
For instance, you can record a snapshot with a custom maximum size
or with a different name.
-s, --session NAME Apply to session name
-n, --name NAME Name of the output or snapshot
-m, --max-size SIZE Maximum bytes size of the snapshot {+k,+M,+G}
-C, --ctrl-url URL Set control path URL. (Must use -D also)
-D, --data-url URL Set data path URL. (Must use -C also)
