Hi, currently I have some ressources on an ESX server available for me: 68 Cores at 2.2GHz, 224 GB RAM. Hardware is distributed on 2 datacenters. My current Graylog setup on this machine: 4x Graylog with 8 cores and 24 GB RAM each, 2 on each datacenter 4x Opensearch with 8 cores and 32 GB RAM each. We started with 3 nodes for each GL and OS and added 2 nodes later on, as log rates increased over time… At the moment we consume about 40-60.000 Logs/s. Now I’m wondering, if this is the optimal setup, or would it be better to have e.g. 2 nodes each (1 on different sites), but with more CPU/RAM attached to each node? Or even a completely different setup? In the beginnuing I installed GL and OS by myself, but the newer installation methods suggest to use Docker. So I’m thinking about changing the setup to docker, too. With docker, would I have GL and OS on one host with two docker containers? Or better - just like now - GL and OS seperated on two machines (e.g. with only one container on each VM)? Thanks for every hint or thought! ---
