Running check disk-usage	Checks disk usage is not too high - above 80%.
Running check eth0-ip	Checks that eth0 exists, is up and has an IP address.
Running check node-name	Validates hostname is correct.
Running check non-default-hostname	Checks the node is not using the default hostname (photon-machine).
Running check podnet-up	Checks that the pod network is working properly.
