-We are running 1 Prometheus, 1 VictoriaMetrics and 1 Grafana server in each datacenter on baremetal servers, scraping 350+ targets (and 3k+ devices collected via SNMPCollector sending metrics directly to VM). Each prometheus is scraping all targets, so we have all metrics in both VictoriaMetrics instances. We are using Promxy to deduplicate metrics from both instances. Grafana has a LB infront, so if one DC has problems, we can still view all metrics from both DCs on the other Grafana instance.
