we have elastic 7.4 running since a couple of years. We have detected a very slow performance every day at around the same time (it's not exactly at the same time every day, but almost). The monitor shows a sudden high latency (see picture). The data time insertion is then so high, that provoques us a really significative delay, as it lastas for several hours. We rotated to a new index and this seemed to help, but we still have this issues... any clue?
Thank you very much!
