It's easy to use, it is very light weight (no heavy dependencies) so you can run in small VMs or containers without problems; You don't need any additional tools/daemons running as an agent of this tool - everything runs from within itself which makes things even simpler since there are no external services required at all! I like how simple yet powerful system health checker we have now with UnixHealthCheck compared eith other solutions out their currently available today such us Nagios / Cacti etc.; The pricing model could be better but still not too expensive considering what they offer here ; We used unixhealthcheck internally when developing our product by testing different environments before deploying them into production environment using Docker images.
