Can I add an ip address range of hosts or do I have to add them one at a time? If I can add multiple hosts via ip address range, what version have this?

Thanks.

Hi @camundson and welcome to the forum.

You can use the bulk import function of Checkmk to import hosts. You cannot use a IP range but you can use a CSV file to do the same. Creating a CSV file for an IP range should be pretty easy.

The bulk import feature is a part of Checkmk for multiple years now so just use the latest and greatest version of Checkmk.

Here you can read more about the CSV file import:

Checkmk does not have any of these features, I think that is good as you should have an IPAM or CMDB where you have your hosts, Checkmk is a monitoring tool not your CMDB!

You should also not add hosts using IP, that is terrible.

On the other side Checkmk have a great API you can use to create hosts. There are also open source tools like CMDB syncer you can use to adapt to any existing CMDB with Python.

There is an auto detection feature that allows to create hosts based on “Network scans”. For best results, install the agent on all hosts that have to be detected and leave the agent in “open” setting (serving agent output on port 6556 to everyone requesting). Then run the network scan for each /24 subnet at once and hope for the best… It usually works.

Another possibility is just using the new auto registration feature. Roll out the prepared client packages on as many hosts as possible and have fun!

To answer @camundson 's question:

  • CSV Import is available in all editions
  • network scan (with all its limitations) is available in all editions (I think)
  • Auto-registration is only available in Checkmk Cloud Edition

There is a function that can create parent-hosts, based on ping. That is a complete different functionality (that normally does not work)
I’m not aware of any other feature, perhaps you can link to that feature?

Hi @Anders

@mschlenker is referring to this

You find it in the Folder Properties (I guess not where you would look for bulk ways to add hosts).
@theyken I guess we found another UX idiosyncrasy

Have a nice weekend,
