Custom Dimensions (covered in this KB article) is one of the more powerful features of Kentik Detect because it enables you to add custom columns to the traffic flow records in your Kentik database, and to populate those custom fields based on a match for a given value in the ingested flow fields. You can use those columns for any number of purposes, including overlaying business information on top of network information so you can run powerful analytics based on the two sets of data.

We recently added the ability to create ranges when defining populators that match on Port and ASN. To define a port range for a populator, first go to Admin » Custom Dimensions and click on a listed dimension to open the Edit Dimension dialog. Choose the Populators tab, then click the Add Populator button, which opens the Add Populator dialog. On the IP Matching tab, define a range in the Port field as shown below. When you add the populator a match will result from any number in the range, not just a single value.
