Loss of individual data streams

I have an issue where one of my data streams will stop but not be detected by the 6 hour monitor and send a warning.

If you view my data for the Redowl01 site, on August 8th I lost the ADS-B UAT data till I did a power cycle on the Pi on August 11 and similarly lost the ADS-B MLAT data on the 24th till I power cycled on the 27th.

Just rebooting doesn’t seem to work. Is there a problem with the 978 UAT dongle?

Is there a way to modify the monitor to detect loss of a data stream rather than the whole output?
