61           Absolute path to the manual pager to use to read the LTTng

63           instead of /usr/bin/man.

67           configuration XML schema.
68
69       LTTNG_SESSIOND_PATH
70           Absolute path to the LTTng session daemon binary (see lttng-
71           sessiond(8)) to spawn from the lttng-create(1) command.

74           variable.

FILES

77       $LTTNG_HOME/.lttngrc
78           Unix user’s LTTng runtime configuration.
79
80           This is where LTTng stores the name of the Unix user’s current
81           recording session between executions of lttng(1).  lttng-create(1)
82           and lttng-set-session(1) set the current recording session.
83
84       $LTTNG_HOME/lttng-traces
85           Default output directory of LTTng traces in local and snapshot
86           modes.
87
88           Override this path with the --output option of the lttng-create(1)
89           command.
90
91       $LTTNG_HOME/.lttng
92           Unix user’s LTTng runtime and configuration directory.
93
94       $LTTNG_HOME/.lttng/sessions
95           Default directory containing the Unix user’s saved recording
96           session configurations (see lttng-save(1) and lttng-load(1)).
97
98       /usr/local/etc/lttng/sessions
99           Directory containing the system-wide saved recording session
100           configurations (see lttng-save(1) and lttng-load(1)).

102       Note
103           $LTTNG_HOME defaults to the value of the HOME environment variable.
