Syslog option for single node

Hi,

Is there any option in SolarWinds NPM that syslog for a single node overwrite after some time (e.g. after 1 hour) while syslog for all other node overwrite after 7 days??? Also how can we determine that the primary NPM server or db server can bear 50 syslogs per second for single node while syslog for remaining nodes are separate??

Regards,
