Viewing the debugging log
You can view the debugging log to see what is happening each step of the way with your data rule or rule set conditions and functions.
How to interpret the debugging log
You work through each step of the evaluation (consider each row to be equal to a step in the evaluation of the rule). In this way, you can isolate errors in your rule logic that are preventing successful rule evaluation.
For
a particular column in your data rule or rule set, you can see how IBM® InfoSphere® Information Analyzer views that data. In the following sample
debugging log, you can see the values for colA, colB, colC, and colD.
- If you apply a function, you can see that it returns a particular value, for example, uppercase(colA).
- When you apply a calculation, you can see the result for that specific record, for example, colC + colD).
- When a condition is evaluated, you can see whether the result returned is true or false.
- You can see whether the record was considered to have met the rule or not.
