HisTrend w/Scooters and Scale fails when file size over 2G per day

I sounds to me like you're just hitting the practical limits of LGH. You should seriously consider using AVEVA Historian here. It is already included under some commercial plans, but even if it isn't in your case, even the cheaper "Local" Edition will probably be an improvement. You can also try it with some limitations even without a license.

It can certainly scale better on the storage side, but the biggest benefit you might see is on retrieval: it supports "best fit" retrieval that is better suited to trending than returning all the detailed raw data, but can still represent the overall signal well. 

Hi, thank you for your reply.

I have a small suggestion. Since the current naming convention for .idx and .lgx files is YYMMDD00, could it be changed to YYMMDDHHmmss? For example, files generated in a day could be named like 240904080000.lgh, 240904090000.lgh, and 240904100000.lgh. This adjustment would resolve the issue.

Thank you.
