Trace Analysis Patterns (Part 57)

Relative Density pattern describes anomalies related to the semantically related pairs of trace messages, for example, “data arrival” and “data display”. Their statement densities can be put in a ratio (also called specific gravity) and compared between working and non-working scenarios. Because the total number of trace messages cancel each other we have just mutual ratio of two message types. In our hypothetical “data” example the increased ratio of “data arrival” to “data display” messages accounts for reported visual data loss and sluggish GUI.
