Trace Analysis Patterns (Part 11)

Saturday, November 7th, 2009

Birds eye view of software traces makes it easier to see their coarse blocked structure:

where further finer structure is discernible and even nested blocks:

Some blocks of output can be seen when scrolling trace viewer output but if a viewer support zooming it is possible to get an overview and jump directly into a Characteristic Message Block, for example, debug messages of repeated attempts to query a database. If a viewer supports message coloring it also helps. Sometimes this technique is useful to ignore bulk messages and start the analysis around block boundaries.
