So, it is necessary to delete the timeseries not only at prometheus db side but also at prometheus client exporter side otherwise they will be recreated. I am supposing the prometheus client exporter saved only the last value for each metric (gauges, counter or others..) until it was not updated with a new set value while, actually all the values previously exposed persist on the prometheus client. Right?
