10/28/2022, 4:41 PMIs there a way to ballpark the memory usage of the container based on the data retention, the number of dashboards etc...

10/28/2022, 4:47 PMI bumped the memory to 10G, and I see it is indeed using 3.7G at times.

10/28/2022, 4:53 PMprometheus’s memory utilization isn’t really influenced by the number of dashboards. It’s more about data cardinality - how many different elements is it collecting in a period of time. More nodes / pods / services / etc will push that up.
Basically, the larger your cluster, the more memory it will need.
