Central Database for DIstributed Setup

Hi, I am trying to setup distributed Checkmk for load balancing. The thing is I would like to have central database to collect all the metrics and then connect Grafana to this database. Influxdb is an option but wonder if there is another widely used solution.

We use Influxdb and it works well for us. Prometheus would be another option. Note that if you send the metrics via Telegraf first, you get several more options via output plugins: Telegraf output plugins | Telegraf 1.9 Documentation

Enterprise edition needed to store metrics on Influxdb? and also integrating Grafana graphs directly to Checkmk?(like replacing Pnp4nagios with Grafana.
