Use Cases and Deployment Scope
We currently use Checkmk to monitor all our IT infrastructure from vmware cluster and vms to our network switches and firewall. We use both Windows and Linux in our organization, the Checkmk agent is excellent in both environments. Checkmk allows us to avoid unexpected issues and downtime due to its in-depth monitoring of services. Also, the graphs and data are an excellent tool for management to show downtime and stats.
