This is the Host Monitor app, created by rFronteddu and maintained by cb218. It is a simple component designed to harvest host information such as Disk/VMemory/CPU status.
The app is designed to run in conjunction with the Testbed Monitor (https://github.com/rFronteddu/testbed-monitor) app, another utility created by rFronteddu.
Sensors are imported from the library https://github.com/shirou/gopsutil. Note that not all sensors produce results for every architecture. The Load Sensor, for example, only works in Linux.
The host monitor will look for a configuration file called hostmonitor.yaml.If no conf file is found, everything is active and statistics are delivered towards localhost.

If using a linux system, the host-monitor.service daemon can be used to build and run the program.
./setup-service.sh
On other systems, the program can be started manually after building.
go build main.go
./main
