FWIW Not sure what you are looking for but I create a LOG file for each running of my CRON jobs. From CRONTAB -l# m h dom mon dow command
0 21 * * * /home/pi/pi_lib_backup.sh > pi_lib_backup_cron.log
0 22 * * * /home/pi/bkp_to_ehost.sh > bkp_to_ehost_cron.log
That won't capture any error messages. For those you need to append 2>&1 to each command as well.
I do it that way too.* I've not checked under Boolworm but under Bullseye and earlier even with EXTRA_OPTS="-L 1" all you get in syslog and/or the systemd journal is messages from the cron daemon not from the called process.
Your other option is to install an MTA** and let the cron daemon email you the command output.
