Automatic export all logs and send by mail
#2

I need to constantly monitor about 80 objects and I thought the best way was to automatically export logs every month and send them by email.

The questions are:

is it possible to do it and if so how?

Is there enough memory in LM to hold the 30-day logs of 80 objects or is it better to use an external USB memory? Here, too, how can I do?

Thanks for your kind response
