Your question is not much clear. Could you please elaborate more and also share the number of nodes in production with their Hardware details. Also share the Status window screen shot to understand about the application configuration.
I would like to know If we can add more then 1200 users in tableau server to access the portal or Is there any limit count for the users. So, The total number of Nodes in production are four nodes, Two are application nodes. Where, One is primary node and the other is application node. The rest two are worker nodes. Please find the screenshot for hardware,
