-lttng-tools command line interface
-
-(Note: as of June 8th, 2011, this document is at [RFC] stage.)
-
-This document describes the "lttng" command line interface.
-
-Authors:
-David Goulet <david.goulet@polymtl.ca>
-Mathieu Desnoyers <mathieu.desnoyers@efficios.com>
-
-We plan to go for a git-alike UI:
-
- lttng command [options]
-
-Where command can be one of the following, and the options are
-per-command:
-
-(note: in this description, options between [ ] are optional)
-
-* Basic options
-
- -v, --verbose # Verbose mode
- -q, --quiet # Quiet mode
- --help # Show help
- --group NAME # Unix tracing group name. (default: tracing)
- --no-sessiond # Don't spawn a session daemon
- --sessiond-path # Session daemon full path
- help/--help/-h # list LTTng commands
-
-* List interfaces:
-
-lttng list [--help] # show list options
-lttng list --events # list all available instrumentation
-lttng list --kernel # list kernel instrumentation
-lttng list --pid n # list userspace app instrumentation by pid
-lttng list command_name # list userspace app instrumentation by command
-lttng list --app # list traceable user-space applications/pids
-lttng list --sessions # list tracing sessions
-
-* Show version
-
-lttng version [--help] # show lttng-tools version and version options
-lttng version --kernel # show kernel lttng version
-lttng version --pid n # show kernel lttng version
-lttng version command_name # show lttng versions for app by command
-
-* Tracing session control
-
-lttng create [--session] name # create a tracing session (default name provided)
- [--output path] # optionally specify the output path
-
----> This command prints
- "Working directory of created session is /path/to/name. Change your"
- "current working directory to interact with this session."
-
----> All the following commands use the current working directory
- .lttng/config file to keep track of the session on which actions
- should be applied.
-
-lttng destroy [--session] name # teardown a tracing session
-lttng start [--session] name # start tracing for a session
-lttng stop [--session] name # stop tracing for a session
-
-
-(note in manpage (warning) about --all and cmd_name:
-"WARNING: this may noticeably slow down your system!")
-lttng add-channel name --kernel [options]
-lttng add-channel name --userspace [--all/--pid n/cmd_name] [options]
- available options:
- --discard (default)
- --overwrite
- --subbuf_size
- --num_subbuf
- --switch_timer_interval
- --read_timer_interval
-
-lttng config --kernel --channel name
-lttng config --channel name [--all/--pid n/cmd_name]
-
-(note: no channel name specified creates a "default" channel)
-lttng add-event name --kernel [--channel name]
-lttng add-event name --userspace [--channel name] [--all/--pid n/cmd_name]
- available options, either:
- --tracepoint (default)
- --marker
- --kprobe address
- --function
- (support list of names: name1,name2,name3... all with the same
- options)
-lttng enable-event name --kernel [--channel name]
-lttng disable-event name --kernel [--channel name]
-lttng enable-event name --userspace [--channel name] [--all/--pid n/cmd_name]
-lttng disable-event name --userspace [--channel name] [--all/--pid n/cmd_name]
-
-lttng add-context name --kernel [--event name] [--channel name] --type context_type [context options]
-lttng add-context name --userspace [--event name] [--channel name] [--all/--pid n/cmd_name] --type context_type [context options]
-
