README

Data Source Syncer

This CLI tool acts as a cron job which remotely syncs data to a given Grafana Prometheus data source. This ensures that the Grafana data source has the following set correctly:

• The Prometheus server URL
• GET HTTP method
• The Prometheus type and version
• Authentication by refreshing a oAuth2 access token periodically

By regularly refreshing the oAuth2 access token, you can configure Grafana to directly query Google Cloud Monitoring (Managed Service for Prometheus).

Google access tokens have a lifetime of 1 hour. This script runs every 10 minutes to ensure you have an uninterrupted connection between Grafana and Google Cloud Monitoring.

For instructions, see the Google Cloud documentation for configuring Grafana to use Managed Service for Prometheus.
