+
+Report validator block production information :
+
+- The number of blocks from each proposer in a given block range.
+- The block number of the last block proposed by each validator (if any within the given range).
+- All validators present in the last block of the range even if they didn’t propose a block.
+
+**Parameters**
+
+`fromBlockNumber` - Integer representing a block number or the string tag `earliest` as described in [Block Parameter](../Pantheon-API/Using-JSON-RPC-API.md#block-parameter). 
+
+`toBlockNumber` - Integer representing a block number or one of the string tags `latest` or `pending`, as described in [Block Parameter](../Pantheon-API/Using-JSON-RPC-API.md#block-parameter). (optional and default to `latest`)
+
+If no parameters are specified, only the last 100 blocks will be processed.
+
+**Returns**
+
+`result`:_object_ - List of validators with their metrics.
