So I am running Prometheus on an Ubuntu server and started running it a while ago by just running
sudo ./prometheus
However, I wanted to append
--storage.tsdb.retention.time=1y
to the end of this command. How can I change the storage retention time of a running Prometheus process without stopping Prometheus from collecting metrics. It is very import that I change the retention time WITHOUT losing the metrics that Prometheus has already collected on this server. Please let me know anything that might help. Thank you.
