# Metric definitions
<a name="metric-definitions"></a>

System metrics are captured using the [Vert.x Metrics Service Provider Interface (SPI)](https://vertx.io/docs/vertx-dropwizard-metrics/java/#_the_metrics).

Auction metrics are captured both in general auction metrics as well as per-adapter metrics for bid-adapters that have been configured.

The full list of metrics with definitions can be viewed in the [prebid-server-java](https://github.com/prebid/prebid-server-java/blob/master/docs/metrics.md) GitHub repository.
