# lttng-disable-rotation

## NAME



           lttng-disable-rotation - Unset a tracing session's rotation
           schedule
    


## SYNOPSIS



           **lttng**[_GENERAL OPTIONS_] **disable-rotation**(**--timer** | **--size**)
                 [**--session** =_SESSION_]
    


## DESCRIPTION



           The **lttng disable-rotation** command unsets a rotation schedule for
           the current tracing session, or for the tracing session named
           _SESSION_ if provided, previously set with the
           lttng-enable-rotation(1) command.
    


## OPTIONS



           General options are described in lttng(1).
    
       **Rotation schedule condition**
           One of:
    
           **--size**
               Unset the rotation schedule previously set with the **--size**
               option of the lttng-enable-rotation(1) command.
    
           **--timer**
               Unset the rotation schedule previously set with the **--timer**
               option of the lttng-enable-rotation(1) command.
    
       **Target**
           **-s** _SESSION_ , **--session** =_SESSION_
               Unset a rotation schedule in 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-options**
               List available command options.
    


## LIMITATIONS



           The **lttng enable-rotation** command only works when:
    
           •   The tracing session is created in normal mode or in network
               streaming mode (see lttng-create(1)).
    
           •   No channel was created with a configured trace file count or
               size limit (see the **--tracefile-size** and **--tracefile-count**
               options in lttng-enable-channel(1)).
    
           For a given tracing session, LTTng only performs an automatic
           rotation when no other rotation is currently happening.
    


## ENVIRONMENT VARIABLES



           **LTTNG_ABORT_ON_ERROR**
               Set to 1 to abort the process after the first error is
               encountered.
    
           **LTTNG_HOME**
               Overrides the **$HOME** environment variable. Useful when the user
               running the commands has a non-writable home directory.
    
           **LTTNG_MAN_BIN_PATH**
               Absolute path to the man pager to use for viewing help
               information about LTTng commands (using lttng-help(1) or **lttng**
               **COMMAND --help**).
    
           **LTTNG_SESSION_CONFIG_XSD_PATH**
               Path in which the **session.xsd** session configuration XML schema
               may be found.
    
           **LTTNG_SESSIOND_PATH**
               Full session daemon binary path.
    
               The **--sessiond-path** option has precedence over this
               environment variable.
    
           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
           daemon.
    


## FILES



           **$LTTNG_HOME/.lttngrc**
               User LTTng runtime configuration.
    
               This is where the per-user current tracing session is stored
               between executions of lttng(1). The current tracing session
               can be set with lttng-set-session(1). See lttng-create(1) for
               more information about tracing sessions.
    
           **$LTTNG_HOME/lttng-traces**
               Default output directory of LTTng traces. This can be
               overridden with the **--output** option of the lttng-create(1)
               command.
    
           **$LTTNG_HOME/.lttng**
               User LTTng runtime and configuration directory.
    
           **$LTTNG_HOME/.lttng/sessions**
               Default location of saved user tracing sessions (see
               lttng-save(1) and lttng-load(1)).
    
           **/usr/local/etc/lttng/sessions**
               System-wide location of saved tracing sessions (see
               lttng-save(1) and lttng-load(1)).
    
               **Note**
    
               **$LTTNG_HOME** defaults to **$HOME** when not explicitly set.
