Grafana can query multiple prometheus data sources: https://www.robustperception.io/switching-between-prometheus-servers-in-grafana-using-data-source-variables
That requires the user to select the required data source from a drop-down. Alternatively, can also put promxy in front of the prometheus servers, and configure grafana to query promxy. All the prometheus servers will appear like one merged server. As another alternative option, you can use remote_write on your prometheus servers to write to VictoriaMetrics, and configure grafana to query the VictoriaMetrics instance (which appears to Grafana just like a prometheus server - indeed it has a somewhat extended version of PromQL). There are other options like Thanos, which may be a bit more involved to set up, but have other advantages (e.g. Thanos can do downsampling and long-term archiving to S3 storage) -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
