One of my customers is using Grafana Cloud as a service, and they send a lot of metrics/DataSeries (remote_write) to the Prometheus instance that is hosted on Grafana Cloud. This made the price of Grafana Cloud service go high, without a real reason, since we’re not using all the metrics that are being sent in our dashboard.
I’ve created a CLI that appends to your current
prometheus.yml file rules, these rules
keep only the metrics that are used in Grafana dashboards.
