in case you do not know beforehand which exact key to look for,
you could first extract all keys with Hash#keys and then
select from the resulting array of keys those that match:

1.9.3p194 :001 > data = {'BD51-5' => 611, 'TOTAL' => 1459071, 'BD51-10' 
=> 1182460}
  => {"BD51-5"=>611, "TOTAL"=>1459071, "BD51-10"=>1182460}
1.9.3p194 :002 > hosts = data.keys.select {|key| key =~ /BD/ }
  => ["BD51-5", "BD51-10"]
