To skip collecting output from =emqtt-bench=, simply pass ~--skip-tags

collect~ to the command above.

Also, one can pass ~-e emqtt_bench_lowmem_mode=True~ to use

=emqtt-bench='s low memory mode.

*** overlays

to run the "overlay files" step, put the files to be copied onto the

servers on =files/=, add the source and destination paths in

=tuning.yml= and execute the playbook passing the =-e emqx_beam_overlays=True=

flag.

ex:

#+BEGIN_SRC yaml

  # tuning.yml

        block:

        - name: overlay stat path

        # .....

      when: emqx_beam_overlays

      vars:

        overlays:

          - dest: "/usr/lib/emqx/lib/mnesia-4.19/ebin/mnesia_log.beam"

            src: "mnesia_log.beam"

          - dest: "/etc/emqx/emqx.conf"

            src: my-emqx.conf
