Page Comparison

First there is no requirement difference between in the requirements for the virtual and hardware appliance.

The needed resource resources are  based on the amount of services, active checks and types of hosts. If you have a lot of SNMP hosts, you'll need more cpu CPU cores for executing the SNMP walks on those.

The one and only overview we have is as you already found this page: https://checkmk.com/product/appliances

Info

Let's give you some an example: Info With this snapin snap in you will be able to check the load of the fetcher and helper. At 70% we recommend increasing these values in the global settings. While you're increasing these values the CPU load and Memory consumption will grow. That's why we also recommend checking these graphs: Info You will find here more information about the fetcher and checker architecture here: https://blog.checkmk.com/checkmk-2.0-cmc https://checkmk.com/werk/11500 Note One Important information about the CheckerCheckers: The checkers shouldn't should not be higher than your cpu CPU core count!

Adjust the helper settings
