F5 cron job explanation

In F5 4200v with TMOS 11.4.0, can somebody explain the cron jobs that are running and what each cron job does? Any documentation will be very useful.

    Some of them may be standard linux jobs. Others are for rotating log files, and yet others may be to check certificate expiry status.

     

    You can read the scripts and see what they are doing. It is self-documenting.
