@clippy thanks, by setting the flag:
osqueryd --verbose --ephemeral --disable_database \
--disable_events false \
--disable_audit false \
--disable_logging false \
--config_path=/etc/osquery/osquery.conf \
and config the file_paths : /etc/%%
but the sql : select * from file_events, can got no result. i have tested touch and VI some files in /etc/.
