DESCRIPTION

The lttng disable-rotation command unsets a rotation schedule, previously set with the lttng-enable-rotation(1) command, for:

With the --session=SESSION option

The recording session named SESSION.

Without the --session option

The current recording session (see lttng-concepts(7) to learn more about the current recording session).

See lttng-concepts(7) to learn more about the recording session rotation and trace chunk concepts.

See the “EXAMPLES” section below for usage examples.

See lttng(1) for GENERAL OPTIONS.

Rotation schedule condition

--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.

Recording target

-s SESSION, --session=SESSION

Unset a rotation schedule for the recording session named SESSION instead of the current recording session.

Program information

-h, --help

This option attempts to launch /usr/bin/man to view this manual page. Override the manual pager path with the LTTNG_MAN_BIN_PATH environment variable.

EXIT STATUS

0

Success

1

Command error

2

Undefined command

3

4

Command warning (something went wrong during the command)

ENVIRONMENT

LTTNG_ABORT_ON_ERROR

Set to 1 to abort the process after the first error is encountered.

LTTNG_HOME

Path to the LTTng home directory.

Defaults to $HOME.

Useful when the Unix user running the commands has a non-writable home directory.

LTTNG_MAN_BIN_PATH

Absolute path to the manual pager to use to read the LTTng command-line help (with lttng-help(1) or with the --help option) instead of /usr/bin/man.

LTTNG_SESSION_CONFIG_XSD_PATH

Path to the directory containing the session.xsd recording session configuration XML schema.

LTTNG_SESSIOND_PATH

Absolute path to the LTTng session daemon binary (see lttng-sessiond(8)) to spawn from the lttng-create(1) command.

The --sessiond-path general option overrides this environment variable.

FILES

$LTTNG_HOME/.lttngrc

Unix user’s LTTng runtime configuration.

This is where LTTng stores the name of the Unix user’s current recording session between executions of lttng(1). lttng-create(1) and lttng-set-session(1) set the current recording session.

$LTTNG_HOME/lttng-traces

Default output directory of LTTng traces in local and snapshot modes.

Override this path with the --output option of the lttng-create(1) command.

$LTTNG_HOME/.lttng

Unix user’s LTTng runtime and configuration directory.

$LTTNG_HOME/.lttng/sessions

Default directory containing the Unix user’s saved recording session configurations (see lttng-save(1) and lttng-load(1)).

/usr/local/etc/lttng/sessions

Directory containing the system-wide saved recording session configurations (see lttng-save(1) and lttng-load(1)).

Note

$LTTNG_HOME defaults to the value of the HOME environment variable.

EXAMPLES

Example 1. Unset the size-based rotation schedule of the current recording session.

See the --size option.

$ lttng disable-rotation --size

Example 2. Unset the periodic rotation schedule of a specific recording session.

See the --timer and --session options.

$ lttng disable-rotation --session=my-session --timer
