I think that I've seen others who setup a cron job and use the checkpointing
feature so that they do not miss anything. You can pipe its output into
logger. You probably also want to cut the first line which has the column
headers.
ausearch --start today --checkpoint /root/last-ausearch .chpt --format csv |
tail -n +2 | logger
On a central log server the input file can grow very big and
very fast.
Probably logrotate is needed to keep it in check.
What happen to the checkpointing feature when the file is rotated ?
How not to miss the last events from the old file and get the new events from the new file
?
Also, the latest syslog plugin can now do interpretation. I think its in
alpha-9 which dates back to Nov 04, 2019.
It really shouldn't be hard to copy and paste the code from ausearch into the
syslog plugin to log directly in that format. I wonder if anyone else would
find that useful?
It would be very useful indeed
