Urchin Q and A: Processing Log Files with Different Formats

Question:

Can Urchin process a log file with two different line formats?

Answer:

The Primary and Secondary lines in the log format are intended to support ecommerce log files, where the secondary lines are related to the primary lines (e.g. secondary per-item logging associated the primary transaction record). It's not a mechanism that can be used for reading two different (and independent) types of log lines in the same log. There's no support in Urchin for doing the latter.
