How to choose
Which platforms does it need to run on?
Start with the operating systems and deployment styles in your environment. Options cover Linux, web, self-hosted, Windows, API and macOS.
Check the supported operating systems field before choosing, then confirm whether the product runs through a web interface, on your own servers or through an API.
Which server activity should it monitor?
Choose a tool that matches the signals you need, such as process or container monitoring, rather than relying on server health alone.
Use the comparison fields for monitoring method, process monitoring and container monitoring. Server auto-discovery can matter when new machines need to appear without manual setup.
What will the monitoring software cost?
Check the free plan, paid starting price, included hosts and trial terms together. Beszel, Cockpit Machines, eZ Server Monitor and Glances list free plans; Checkmk lists a free plan and paid service from €190 per month on an annual plan.
Paid examples include LogicMonitor from $16 per month and eG Enterprise from $100 per month. BizTalk360 and FrameFlow list pricing on request, with 30-day trials.
Do you need open-source code or a public API?
If you need to read or change the code, check the open-source mark and the licence for the tool you are considering. Beszel and eZ Server Monitor list open-source status.
For connections to other software, check the public API mark and the API field in the comparison.
