Adding new metrics
There are two kinds of metrics that can be logged: values and events.
Values correspond to measurements of a certain quantity, like number of online players or the update diff time.
Events are something that occurs in an instant of time, e.g, a player login, worldserver shutdown, etc.
To log new metrics, call TC_METRIC_EVENT or TC_METRIC_VALUE and add a new graph to the dashboard.
Examples
// Registering player logins: in WorldSession::HandlePlayerLogin(LoginQueryHolder* holder)
TC_METRIC_EVENT("player_events", "Login", pCurrChar->GetName()); // TC_METRIC_EVENT(category, title, description)
// Logging the update diff time: in World::Update(uint32 diff)
TC_METRIC_VALUE("update_time_diff", diff); // TC_METRIC_VALUE(category, value)
- category: Arbitrary string, table where the values and events are stored. By convention, event logs should be suffixed by "_events".
- title: Name of the event log.
- description: Additional info about a log event.
- value: A measurement, it can be a
