The SPG9000 data exporter is a python application. It is provided here in the context of a Docker container running Python Slim, but the script can be adapted to run as a Linux service.
By default Flask runs on port 5000, but this can be mapped to any port on the computer running Docker.
Visit http://{docker ip}:{port}/metrics?api_key={api_key}&target={0.0.0.0} where {docker ip} is the IP address of the docker installation, {port} is the external port that is mapped to container port 5000, {api_key} is the configured API key on the Telestream SPG9000, and {0.0.0.0} is the IP of the Telestream SPG9000 to get metrics from.
