Checkmk Werk 12995: Graph don't confuse metrics names that are like numbers for values

ID: 12995 Title: Graph don't confuse metrics names that are like numbers for values Component: Multisite Level: 1 Class: Bug fix Version: 2.1.0i1 Some users name in local checks metrics that represent Network subnets, by the subnet numbers, eg. "10.172". Although it could be considered a poor naming practice checkmk now manages to recognize them as metric names out of the performance data instead as values.
