Thanks for your answers, @mierzwa and Ben @mierzwa, I have checked the robust perception blog post you have linked and it really seems like my Prometheus is using too much memory. I have only around 20k series, but with quite high cardinality over a long period of time. If we just look at a few hours or days the churn should be very low / zero and only increase when ever an API endpoint gets called the first time and so on.
@Ben, the Prometheus is using AWS EFS for storage and so the disk size should be unlimited. It sits currently at just 13 GB while resident size is at around 2 GB and virtual memory around 7 GB. The node Prometheus is running on has 8 GB of RAM. Now that you have mentioned storage, I have read quite some time ago that Prometheus does not officially support NFS and I think the AWS EFS volume is mounted via NFS into the node. --------------------------------------------------------- Here is the info I get from the Prometheus web interface: https://trallnag.htmlsave.net/ This links to a html document that I saved [email protected] schrieb am Montag, 26.
