# Grafana Clickhouse Docker Log Aggregation
This demo project can aggregate logs from Docker containers and store them in Clickhouse. In the `dashboards` directory you can find dashboard examples for specific log format. `Logs + Structured via Query` is recommended because the other one is deprecated now.

**Note**: dashboards are tuned for structured logging (JSON log records).

Obviously, you'll need Docker:
1. `make migrate` (use `clickhouse-client` inside container and execute migration SQL directly if migrator doesn't work).
2. Navigate to `http://grafana.test` or `http://localhost:3000` (if you did not configure Traefik locally), use `admin:admin` as credentials.
3. Import `dashboards/Logs + Structured via Query.json` dashboard.
1. `make all`
2. Navigate to `http://grafana.test` or `http://localhost:3000`, use `admin:admin` as credentials.
3. Create your own dashboard or import those I provided (`dashboards/` directory). Replace data source UUID with correct one if needed.
4. Run any Docker project with structured JSON logs.
5. Done.
