Hardware and software requirements - Debian 11 Raw 2.1

Debian 11

Hi, we want change our old checkMK 1.2.8.p9 in Centos to 2.1.0p9 in Debian.

We want know what the minimum hardware requirements are and what the dependencies are.

We have now 3500 Hosts and also more of 13K Services



SSD’s ?
how often are you planing to check the services, default settings?


The direct package dependencies can be found in the package information:

$ dpkg --info check-mk-raw-2.1.0p9_0.bullseye_amd64.deb | fgrep Depends:

Yes the disks are SSD.

The times we handle when monitoring are various.

From 5 min, 10 min, 1 hour, 24 hours.


Hi Martin.

Thanks for the info =)

Hi zorel,

3500 hosts and 13000 services? So the majority of your systems is ping only?
that requires very little resources and the whole instance is fairly small. I’d estimate that even 4 cpus + 4 gb ram would be enough. It’ll be difficult to find such a small x86 server nowadays so I guess you’ll be fine ;).


Hi Gstolz.

Thanks for you answer!

Currently most of the services we analyze are CPU, RAM, Disk, SWAP. But we also analyze services, checks through sh and pings.

Do you agregate more Ram


is that a question if so, what do you mean? can you rephrase it :)?
