I was getting some bad numbers from Historian Store & Forward.
So, after some optimization on deadband and sample mode, I got my datapoints/sec really down.
How can I force Historian to delete old data? I had partitions by months and I just set it to days to try to force it to prune last month but I still see the table there.
After some time I saw in the logs that there was some data pruning:
But I still see some errors:
I also notice that Local Cache datapoints/sec are always lower than Database Storage datapoints/sec. I would expect the Database Storage to be higher. That way it would be able to log every data point, otherwise it makes sense that it’s dropping datapoints.
