How to ensure sufficient capacity on your HDD to withstand a network disconnection with the PI server for several days.
Thanks for posting on PISquare. I'm not entirely sure what your are asking so forgive me if my answer does not answer your question.
From the title of the post, I believe that you are asking what is the maximum amount of data the buffer can store. The maximum is based on the physical disk size where the buffer is storing the data before sending it over to the PI Server.
We can check the buffer capacity from the Buffer Manager which can be opened from the ICU>Tools>Buffering.
In the example above, I have space for 1008 days of data. This number is calculated based on the available free space on the drive, how many events are being sent per second and how much space each event takes up. This calculation continually updates so you can see how the buffer responds to high throughput periods and low throughput periods.
I hope this clarifies your question and if you have any additional questions, please don't hesitate to ask.
Thanks for your quick reply.
For now, I will use the buffer manager as suggested. From there I can draw some conclusions for the actual settings required per interface. This has helped me to the right track. If still questions remains, I will come back to you.
