lttng-stop(1) ============= NAME ---- lttng-stop - Stop LTTng tracers SYNOPSIS -------- [verse] *lttng* ['linkgenoptions:(GENERAL OPTIONS)'] *stop* [option:--no-wait] ['SESSION'] DESCRIPTION ----------- The `lttng stop` command stops the various LTTng tracers for a given active tracing session. Stopping the LTTng tracers has the effect that all enabled event rules within enabled channels cannot make event sources _emit_ trace events anymore. A tracing session with no running tracers is said to be _inactive_. Inactive tracing sessions can be set active using the man:lttng-start(1) command. If 'SESSION' is omitted, the LTTng tracers are stopped for the current tracing session (see man:lttng-create(1) for more information about the current tracing session). Otherwise, they are stopped for the existing tracing session named 'SESSION'. `lttng list` outputs all the existing tracing sessions (see man:lttng-list(1)). By default, the `lttng stop` command ensures that the tracing session's trace data is valid before returning to the prompt. With the option:--no-wait option, the command finishes immediately, hence a local trace might not be valid when the command is done. In this case, there is no way to know when the trace becomes valid. include::common-cmd-options-head.txt[] option:-n, option:--no-wait:: Do not ensure that the chosen tracing session's trace data is valid before returning to the prompt. include::common-cmd-help-options.txt[] include::common-cmd-footer.txt[] SEE ALSO -------- man:lttng-start(1), man:lttng(1)
