The following XDCR metrics can be queried by means of the REST APIs described in [Statistics](../rest-api/rest-statistics.md). > [!TIP] > * The x.y.z badge shows the Couchbase Server version the metric was added in. > * The type / unit badge shows shows the Prometheus [type](https://prometheus.io/docs/tutorials/understanding%5Fmetric%5Ftypes/) and [unit](https://prometheus.io/docs/practices/naming/#base-units) (if present). | xdcr\_binary\_filtered\_total7.2.1 counter Number of documents filtered that were binary documents | |
