Events per seconds / Volume size - Syslog event subscription

Hi,

I've receive a request to send the Change Auditor events to a syslog collector...  But for planning purposes they are wondering the ingestion rate (EPS / Volume Size) for the CA events.  Is there a way I could generate a reports with the information : Number of events per seconds, Size (MB, GB) of data received by the Coordinator???

Thank you
Martin
