Query String Grouping

Query String Grouping

Query String Grouping lets you integrate a large number of fields together.

Query String Grouping is specific to each profile, but works well in transformations as shown in this example:

1. Create the pairs you wish to bundle by adding a custom configuration file ( E:…\Dataset\Log Processing\SC Fields.cfg) and then adding the Transformation Type BuildNameValuePair as a parameter.

   2 = BuildNameValuePair:  
         Comments = Comment: 0 items 
         Condition = AndCondition: 0 items 
         Delimiter = string:  
         Input Columns = vector: 1 items 
           0 = Column:  
             Column Name = string: e100 
             Field Name = string: x-cust100 
             ...  
     (all the fields you wish to build)
             Name = string: Custom Events 
             Output = string: x-event-list       
   

2. Create a new file for extracting the condensed data into the fields you wish to use by adding a custom configuration file ( E:…\Dataset\Transformation\SC Fields Transformation.cfg) and then adding the Transformation Type ExtractNameValuePairs as a parameter.

   2 = ExtractNameValuePairs:  
         Comments = Comment: 0 items 
         Condition = AndCondition: 0 items 
         Delimiter = string:  
         Input Field = string: x-event-list 
         Name = string: Custom Events 
         Output Columns = vector: 1 items 
           0 = Column:  
             Column Name = string: e100 
             Field Name = string: x-cust100 
             ...  
     (all the fields you wish to extract) 
             Name = string: Custom Events 
             Output = string: x-event-list   
   

Other Uses

If you have many fields with custom evars, props, and variables, during log processing you can build a name value pair to combine fields in a report. For example, you can build named-value pairs into combined fields to reduce the tempDB file size.
