Data Quality issue should be created in case of no incoming data

[XxChauhanxX]

In the current implementation if the Data flow stops at the Tempus broker then there is no alert for Data Quality (Frequency)

The Tag presence check should not be present since the frequency of Data points is checked based on the Tags, so a separate Tag presence check is not needed.

Use configured time window for frequency check instead of calculating it from the received data.
