Hardware specifications with v1.6

Hi,

Based on your experience, what minimum hardware specifications do you recommend to monitor 50, 100 or 500 hosts?

Thank you

Hi, I can’t speak for all people but I would say it really depends on your scenario. The amount of hosts doesn’t say much about the size of you system because you can have 100 Hosts with only 100 services or 100 hosts with over 9000 services for example.

But to give you an idea what you might need you can use the hardware specs from the Checkmk hardware appliances.

But remember that they are running with the microcore of Checkmk that consumes much less CPU ressources.

Maybe more people can give some insights from their setups for comparison.

Thanks for your reply Norm.

The infrastructure to be monitored are linux and windows servers. An average of 20 services per host. These are the services that the agent discovers by default.

Do you plan to use the CRE or CEE version? The checkmk microcore and classic nagios core work different and also need different CPU and RAM sizing. Also the number of users who are accessing the installation could influence the sizing.
But at this small scale a system with 2 CPU cores and 4 GB RAM should be suitable.

Thanks for your reply Tosch.

The version is CRE and the number of simultaneous users does not exceed 10.

Other question, please:
Does the CRE need more CPU cores if the hosts are monitored with SNMP than with the agent?

Thanks!

Definitly yes. SNMP is more performance hungry generally and CRE/Nagios uses command line utilities to handle SNMP whereas in CEE/microcore this is handled inside the check helpers.

Hi,

For this amount, i suggest a 2vCPU, 4GB RAM, 100GB Disk but there is a very important thing. It dependens how many active checks you will have. This is a very big influence in the performance of the server.
