Master host CPU and RAM resources

You can create a multi-host or single-host deployment of Control Center, on real or virtual hosts.

Zenoss recommends that all production deployments include one Control Center master host and two or more delegate hosts. In this configuration, the master host runs in its own, separate resource pool, and runs only Control Center internal services. Delegate hosts run application services in other resource pools.

  • For multi-host deployments, the master host typically requires 4 real or virtual CPU cores and 16GB RAM. Very large multi-host deployments may require 8 CPU cores, but no additional RAM.
  • For single-host deployments, the master host requires a minimum of 8 real or virtual CPU cores and 64GB RAM. Actual CPU and RAM requirements depend on application load.
