so the rancher cluster itself wont need more than 3 nodes and around 4gi mem per node (8 to be super safe)
the prometheus stuff will take A LOT more memory
id recommend having a pool just for rancher, and a second pool dedicated just for monitoring

makes sense
thanks
I had all that on older computers on-premise with not enough IO/spindles to handle the needs of prometheus and the cluster itself. That was terrible 🙂

ah yeah
both rancher and prom are really i/o intensive depending on how you set them up
rancher loves to write little tiny logs for EVERYTHING haha

I run rancher-monitoring without any modifications and it uses on average 7G of RAM, spiking up to 15 or 20. That's with about 100 node cluster, with a few hundred containers running.
