We are planning to use ELK stack with beats for few of our applications & OS real time monitoring. Currently I am doing some POC. I couldn't find any documentation regarding sizing when considering to build a ELK cluster.
I am looking for a information like for 1000 servers data processing (metric beat & some other custom beats) what should be the size of ELK stack cluster.
CPU, Mem, Disk etc. calculation
along with Kernel parameter for RHEL 8.
