Generate Prometheus config.yml flile content using grafana bridge

You must add an individual scrape job to the Prometheus configuration file (prometheus.yaml) for each IBM Storage Scale performance data acquisition sensor that you want to expose to Prometheus. Grafana-Bridge can pre-generate the contents of the configuration file in yaml format based on the available cluster configuration data. As a prerequisite, you must have installed the PyYAML Python packages on the host running the IBM Storage Scale bridge for Grafana before starting it.

Check if the PyYAML package is already installed.

# pip list | grep PyYAML

If not, install it and restart the grafana-bridge service.

# pip install PyYAML

# systemctl restart grafana-bridge

Enter the prometheus.yml endpoint in the address bar of a browser using the Prometheus Exporter plugin port

http(s)://<gafana-bridge-ip>:<prometheus-exporter-port>/prometheus.yml

You can also retrieve the content of the prometheus.yml via Curl REST API call
