Statistic and metric logging in TrinityCore is implemented using two projects, InfluxDB, a time-series data storage and Grafana, graph and dashboard builder for visualizing time series metrics.

Installing InfluxDB

1. Download and install InfluxDB from https://influxdata.com/downloads/#influxdb for your platform

   Nota
   Windows is not currently available officially but an older working version can be found at https://github.com/mvadu/influxdb/releases

2. Create an user and a database for TC using the Influx CLI

3. Login with username admin and password admin (defaults can be changed in Grafana's .ini files)
4. Go to Data Sources → + Add Data Source
   Name: Influx
   Type: InfluxDB
   Url: http://localhost:8086
   Access: Proxy
   Database: worldserver User: grafana Password: grafana
5. Go to Dashboards → Import and import each .json file in TrinityCore's /contrib/grafana

Configuring TrinityCore

1. Edit the worldserver.conf file
2. Set Metric.Enable = 1
3. Edit Metric.ConnectionInfo with connection details (e.g "127.0.0.1;8086;worldserver")
4. Start worldserver, the dashboard should now start receiving values

Adding new metrics

There are two kinds of metrics that can be logged: values and events.
