-The `ibstat` collector reads either data through the `perfquery` command or the sysfs files below `/sys/class/infiniband/<device>`.
+The `ibstat` includes all devices that can be found below `/sys/class/infiniband/`
+and where any of the ports provides a `lid` file (`/sys/class/infiniband/<dev>/ports/<port>/lid`)
+The devices can be filtered with the `exclude_devices` option in the configuration.
+The collector reads data through the sysfs files below `/sys/class/infiniband/<device>`.
 
 Metrics:
 * `ib_recv`
 * `ib_xmit`
+* `ib_recv_pkts`
+* `ib_xmit_pkts`
 
 The collector adds a `device` tag to all metrics
