Grafana dashboard
Example Grafana dashboard
definition as JSON
or at grafana.com

Grafana and Prometheus example project
This repo contains example docker-compose.yml with blocky, prometheus (with configured scraper for blocky) and grafana with prometheus datasource.
MySQL / MariaDB
If database query logging is activated (see Query logging), you can use following Grafana Dashboard as JSON or at grafana.com
.
Please define the MySQL source in Grafana, which points to the database with blocky's log entries.
Postgres
