Comments and Reviews
Checkmk has a lot of features, but sadly since version 2.0 the raw version is no longer 100% free. It's limited to 25 hosts, so it is more freemium than free. If you don't reach this limit or you are willing to pay the enterprise solution it's still the first choice.
I have the raw version installed at home and have 60 hosts without any problem. Was on 2.0 and migrated to 2.1 recently.
Checkmk is easy to setup and operate
Suitable for both basic and complex monitoring. Rule-based configuration method is not familiar to most but offers flexibility esp when adding new hosts/services. Nagios users will find it very familiar
