SQL Collector Axiom issue

There is a dataset which is using SQL collector to get data.

The sample interval is about 10 mins for example.

In case the data is not updated due to error on data source error or something

SQL collector seems to have this issue on axiom flat-lining at last good value.

 If some tags are not getting updated, I think there should be no data,

but until it's flat-lining until it's updated with new values.

This flat line can be confusing, as users don't know whether it's not being updated for a long time

or whether they are just getting the same values over and over.

and this can result in events not properly working, as well.

Would there be any solution to make it 0 or no data? when it's not updated?

Thanks!
