Estimated hard disk usage when deploying command authorization and accounting

[xili5]

Hi Expert,

My customer asked to deploy command authorization and accounting on ISE. Since input of every single command line would trigger logs, it is necessary to assign hard disk much bigger. So is there an useful method to evaluate the logs size, like 100 items consume 1K, something like that,  so that  I could know how much hard disks would be assigned to VM ISE and how to define tacacs log retention period.

br,

Xin

Thanks, Jason. The web link you provided is very useful for me.

If I define "retention period" as 90 days without repository enabled, does it mean the data prior to 90 days will be purged automatically by ISE?

Yes.
