Do you really need long term? I hate throwing away data but realistically I never really need old performance data. Some stats data is worth keeping but you can extract a few important time series and store them elsewhere.
In any case, Prometheus is throwing away data if a scrap can’t be done. As clearly described on the website, prometheus is not a metrics system.
So influx and Prometheus are quite different.
Mistake in my previous message. I wanted to say that Prometheus is not a log system. Metrics could be lost in scraping issues. This is ok in some cases but you have to know that you can loose data.
