I have configured the cron by refering this link, yes I have successfully configured. now I can able to see newly created three cron logs file they are
magento.cron.log, it is logging like
Ran jobs by schedule.
setup.cron.log still now it is empty
update.cron.log, it is logging like
readiness check failed
in log file they just print message every minutes, I felt not much details present in the log.
my question is what is the use of cron and cron logs, is it helpful to debug?
please suggest neat and simple way to understand cron and cron logs?
