Show in HA result of daily synch

Hi all!
I have a home server with HA core installed, the server is also managing the daily backup of my storage files, using rsynch and a dedicated script file running daily.
Each time rsynch runs it save a file logging new file, delete file,…
I would like to modify the scrip in order to postprocess the log files and save a summary info (number of file copied, number deleted,…) in a format usefully to be showed by HA.

Have you some suggestions and ideas on how pass this data to HA? And how best format show them in HA?

Thanks a lot!
