InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
2 and 3 You can use the GUI in grafana to build Prometheus queries in grafana. I also prefer push over pull. I found out Victoriametrics is a thing and let's you push data as if it was influxdbv1 and add it to grafana as a promtheus data source. I deploy everything via ansible and here is the link to the repo
