Hi everyone!
I'm doing a study about how much time we have in our prometheus instances.
First of all, I thought that prometheus memory grew because number
timeseries ingested. I thought like this because timeseries stay in
memory to recover informations more faster.
But I got timeseries from last 3 months and I found that my timeseries
ingested was grew little, like this graph and in the same time, I
needed to increase the memory ram and CPU of the our instances sometimes.
There was an interesting talk at the recent PromCon EU
(https://promcon.io/2022-munich/talks/why-is-it-so-big-analysing-the-m/)
which is available on YouTube, but basically the main memory usage is
generally due to the number of time series, with only a very minor usage
due to queries.
