Hello everyone,

I have a question regarding the buffer's handling of discarded data.

Some time ago, the hard disk capacity of the Historian server (Receiver) reached its limit, causing the buffer to start accumulating data on the Sender side. We went several days without noticing this issue until we discovered it and expanded the disk capacity of the Historian. Afterward, the buffer began transferring data immediately, and we managed to recover some of the lost data. However, the problem is that I didn't recover all the days... I lost roughly half of the data.

I believe what happened is that the buffer reached its limit and started discarding data. The issue is that I assumed the buffer would discard new data, but it actually discarded old data, resulting in the loss of older data while keeping the newest.

Is there any configuration available to adjust this behavior?

Thank you.
