StatsD is easily integrated with Prometheus pull model — just substitute Brubeck with statsd_exporter and scrape it with Prometheus. I’d recommend looking into available remote storage options if you decide switching to Prometheus, since Prometheus’ local storage isn’t suited for large volumes of data and for big retentions. Take a look at VictoriaMetrics as long-term remote storage for Prometheus, since it is easy to operate and it speaks PromQL — Prometheus’ native query language.
