Environment Monitor uses an attached sensor module to report various environmental readings to be recorded in metrics2.
The reported metrics are:
This monitor currently uses the DLP-TH1C sensor module which is connected to the host via USB. The //skolo/go/sensors package communicates with the DLP-TH1C over serial.
To run this locally a DLP-TH1C sensor module needs to be connected to your workstation. It can be run from the //skolo
directory as so:
$ go run go/environment_monitor_ansible/main.go \ -serial_device=/path/to/serial/device -metric_prefix=<prefix>
for example:
Here /dev/ttyACM0
is the sensor module device - yours will likely differ.
$ go run go/environment_monitor_ansible/main.go \ -serial_device=/dev/ttyACM0 -metric_prefix=testing_
The metrics, which take ~30 seconds to get their first reading, can be read by:
$ curl -s http://localhost:20000/metrics
There is also a sensor library tool in //skolo/go/sensors_tool
.
