Any idea as to how much log data your clients generate?
The first section "Management Server Log Settings" is just strictly events related to the SEPM. You can check these logs by going to Monitors >> Logs and set the Log type to System and for Log content there are 5 options. You can loko thru each one. These fill up pretty quickly though.
Client Log Settings can be another large amount of data, especially if you are logging firewall traffic logs.
Risk Log Settings may be the smallest amount of data, depending on how you use them but they could be pretty large as well.
Depending on the specs of your server and DB, performance may take a hit. Do you have an option to send to syslog? This would be ideal
