We observed a systematic delay of about 35 s between the change of water level in a tank and the graphed representation in grafana : the changes appear to take place 35 s too late!

Note the master connection was active and was delivering older data (the queue was obviously not empty and the thread was trying to empty it at a reduced pace).

After rebooting the ardas system, the problem disappeared. We have to check the logs...

The messages annotations in grafana seemed to be placed at the right time!
